All You Need to Know About the Types of Flanges

The primary purpose of the flanges is to help connect pipes, valves, and pumps. With a range of materials available and a variety of types and styles, you need to be aware of all the aspects and get adequate information beforehand in order to make the right choice. The most commonly available types of flanges that you can use in your industries are given below;

SLIP-ON FLANGES

Slip-n flanges are the type of flanges that are connected to the pipe or the fittings. The connections are made by getting it welded inside and outside. In other words, these flanges are ring-shaped structures placed over the pipe’s end. As the name suggests, these flanges are supposed to have a slipping property, which means they slip over a pipe. Following the same point, they are designed to have a larger bore size and the diameter of the outside pipe as well.

Benefits

  • They save a lot of safe because of their compact and slim shape.
  • They are the best-used options in liquid industries, with a low risk of leakage and spillage.
  • They are easily affordable.
  • They are used in low-pressure and temperature areas.
  • They are among the most popular and frequently used flanges types.

 

WELD NECK FLANGES

Other names for weld neck flanges are high high-neck flanges or tapered hub flanges. These flanges systems are designed in a way that they have a well-balanced neck that helps in transferring the tension of the pipe. The channel is also beneficial in reducing the overall pressure that otherwise would accumulate at the flange button and would result in distortions. Most customers prefer them because they are capable of functioning even at high temperatures.

Benefits

  • They help in distributing the mechanical stress of the pipe.
  • These flanges can tolerate extremely high temperature and pressure conditions.
  • You can easily connect them with either fittings or pipes.
  • They are approvingly resistant to corrosion and rust.
  • They reduce the overall friction and also offer minimal to no turbulence.

 

SOCKET WELD FLANGES

Socket weld flanges are the type of flanges that adjust the incoming pipe into the socket to great a fitting. The connections are made with the help of fillet weld on the exterior. They are mostly preferred in the situation when there is an issue with space management, as they can even fit perfectly and effortlessly and narrow spaces. They are not preferable to be used for something other than critical services.

Benefits

  • Their sleek and small design makes them an ideal choice for small pipes.
  • They offer double fatigue strength than the double-wedged flanges.
  • The risk of leakage is shallow.
  • Their static power is the same as the slip-on flanges system.
  • They are commonly used in areas of high pressure.

 

BLIND FLANGES

Blind flanges are the type of flanges that do not have a bore at the center of the flange system. Such kinds of flanges are used to terminate or seal the ends of pressure vessel openings, valves, and pipes. In short, they are helpful in stopping the flow of liquid. Because of the simple design, these flanges can be bolted and unbolted easily compared to the other flanges types.

Benefits

  • They have high mechanical stress-tolerating abilities and are known to strengthen the pipe system.
  • They are capable of sustaining high-pressure areas.
  • They are beneficial in sealing the opening of the nozzle effortlessly.
  • They can function well, even if located at greater distances from the work site.
  • They are easier to clean and inspect and thus can preserve a lot of time and money.

 

LAP JOINT FLANGES

Such flanges have a flat face and are always used in combination with a stub end. They are usually preferred to be used in expensive pipes and closely resemble the slip-on flanges, except for a few differences in the manufacturing design. They are highly affordable and help reduce the piping system’s overall cost as they minimize the need for expensive materials.

Benefits

  • They are fortunate to use, and they do not cost much money.
  • They help simplify and ease the bolting operations.
  • These flanges have freedom of movement around the pipe and can move quickly without restrictions.
  • They are easy to assemble, and the pipe can be removed easily at any time for cleaning purposes.

 

THREADED FLANGES

These flanges are also very much similar to slip-on flanges, but the only difference is that they have a tapered thread. This addition of tapered thread helps threaded flanges to get attached to the pipes without welding.

Benefits

  • They are ideal be used in pipes that have a small diameter.
  • They are used in low-pressure and low-temperature areas.
  • They are incredibly beneficial to be used in explosive places like gas stations and power plants.
  • There is no need to get the pipe welded to the flange, which saves a lot of time.
  • They are designed to withstand big shocks, vibrations, and pressure changes.

Gasket

Gasket

What is Gasket?

Flange gasket is intended to close the gap between two pipe sections. Gasket is also commonly referred to as an O-ring or washer. These objects often come in a variety of sizes and forms based on their intended use. Of course, flanged surfaces are used to join the majority of pipes. The joint between two pipes is not level or completely smooth. Instead, it has a flange, which flares out. Flange gasket is used for flanged surfaces like this one.

Gasket

How Flange Gasket Works?

Like the majority of other gaskets, flange gasket functions similarly. They produce a sealed mating surface when installed, preventing leakage of water or other liquids. Water or other liquids usually flow through pipes. Water or other liquids may seep out through this mating surface if two pipes are linked together. Flange gaskets seal the surface to stop this from happening.

When used alone, pipes typically do not provide a sealed mating surface. This is particularly valid for pipes with flanged surface. This is particularly valid for pipes with flanged surfaces. Water and liquids can easily escape through the fractures on flanged surfaces because they are flared. Installing a flanged gasket is an easy way to stop leaks. To ensure that water or other liquids stay inside the pipes. The bordered gasket will adapt to the shape of the flanged surface.

Flange Gasket

Type of gasket flange

Non-metallic, semi-metallic, and metal gaskets are the three main types of flange gaskets.

In low pressure, low temperature, and noncritical service applications, non-metallic flange gaskets are employed. To fit in the grooves of the flange face, these flange gaskets are constructed from a soft substance.

Based on the needs of the Product and Service, the Semi Metallic Flange Gasket or Composite Flange Gasket is a blend of metal and nonmetal components. The Spiral wound Flange Gasket, which is appropriate for a wide variety of temperature and pressure Classes, is the most commonly used. A metal outer ring is typically fashioned into a spiral winding with a filler of graphite or PTFE, along with stainless steel or another alloy, to seal the flanged connection when squeezed.

The Metal Flange Gasket, also known as the Ring Type Joint Flange Gasket, is an all-metal gasket used to seal joints made of carbon steel, stainless steel, or other exotic alloys. The RTJ Flange Gaskets are intended for use in demanding situations involving high pressure and high temperature. A rectangular or oval cut groove on the face of the mated flanges receives the RTJ Flange Gasket. These flange gaskets are pressed into the grooves when they are tightened, creating a reliable seal at the flanged connection.

Properties of a Gasket

The gasket material ought to be highly tensile, flexible, and low in density. Additionally, it should be durable and resistant to internal pressure and chemicals. Additionally, it must adhere well to both itself and whatever else it touches.

The appropriate gasket will prevent corrosion in addition to sealing. Consideration must be given to additional abrasion, vibration, impact, and temperature fluctuations.

Nevertheless, strength is the most crucial component in every gasket application. It must be strong enough to sustain pressure without breaking under typical circumstances. This is done so that it can perform its main duty of sealing tightly.

Gasket

Applications of a Gasket

There are various industrial applications for gaskets. Petrochemical, gas, machinery, and plumbing are some of the examples. In the workplace, gaskets in pumps, pipes, valves, and machinery are a few examples. The simplest approach to condense these is to consider the statement, “If it needs sealing and it does not move, it probably uses a gasket.”

Most people typically associate head gaskets with the metal or stainless steel gaskets used in automobiles. However, as you can see, there are many different types of gaskets.

Most frequently, they are passed off as something else, such as washers or O-rings. They all perform important tasks in a variety of applications.

slip on flange

How are Gaskets Tested?

Gasket goes through testing including hot compression tests as part of the evaluation procedure. This test establishes the maximum heat that the gasket can endure without material degradation or failure.

The next step is to inspect the sealant for any leaks and to look any other issues, such as pinholes or cracks. Before the product leaves the factory, professionals will undertake a thorough evaluation of it as the last step in the manufacturing process.

Type of Valves Used in Piping

Type of valves used in piping

Valve

What is a valve? 

A valve is a device that controls the flow of fluids by opening and closing. Any substance that can flow freely is considered a fluid in a scientific setting, and valve can utilised either liquids or gases. Also, it regulates the flow of fluid in hydraulic, pneumatic, irrigation, plumbing, and motor systems. The venerable pre-transistor vacuum tube is sometimes referred to as a valve. 

Moreover, the simplest valve is one-way flap devices that open with backflow pressure and permit flow in one direction and shut to stop flow in the opposite direction. In essence, this is how the heart’s valves function. Furthermore, it can operates manually or with a motor, and in addition to being powered by the physics of flow. They can also be powered by pressure or temperature. 

Other than that, levers, pedals, hand knobs, or wheels are commonly used to crank a screw-turned stem on manual valve. A valve may include geared mechanical inner workings that activate the valve ball or disc against its seat, which may contain a gasket. Also, it can control fluid to onw or more than four ports. 

The functions of a valve in piping systems.

Valve plays an important role in boosting process efficiency, improving quality control, and maintaining process safety and reliability. The primary consideration in valve selection is the valve’s desired function. It is also used in piping systems for a variety of reasons, including: 

  • Initiation or cessation of fluid flow.
  • Controlling flow rates in a pipe system.
  • Pressure regulation and fluid temperature in a pipe system. 
  • Redirecting flow from one path to another and restricting flow for system balance or to avoid over-pressurization.
  • Prevent fluid reverse flow
  • In the event of a system breakdown, the flow is halted. 
  • Improving safety in a pipe system by alleviating pressure or vacuum.

 

Type of Valves.

Different types of valves use in different sectors. These are the type of valves: 

i. Ball Valve

A spherical plug is used in ball valve. The spherical plug serves as a control element. It is commonly utilised in the chemical process industries. Moreover, it is utilised in situations where throttling and shutting down are essential. It has excellent flow properties. In addition, it is made up of a two-way globe with a ball that spins between robust seats. It is small, takes little maintenance, and does not require lubrication. Moreover, it is offered in three different patterns: venture, reduced, and full port. It can be closed or opened by turning the ball a quarter turn. And also, it does not provide adequate throttling. It is available in sizes ranging from 6mm to 900mm and it can withstand pressures of up to 500 kg/cm and temperatures of up to 300°C. 

Ball Valve
ii. Gate Valve

The gate valve operates through the reciprocating movement of a disc within its body. It can have either a single or double disc. It is used to turn off the power. The shut off of a twin disc valve is satisfactory. 

Besides that, the stem of a gate valve might be rising or non-rising. It come in a variety of diameters ranging from 12mm to 30mm and even larger. Also, it is lightweight, inexpensive, and has a low pressure drop. Hence, it provides accurate flow control. It also can withstand pressures of up to 20kg/cm2 and temperatures of up to 675°C. Cast iron, carbon steel, stainless steel, ductile iron, bronze, nickel alloys, and other materials are used to create gate valves. Gate valve of the rotating disc type with a quick action lever actuator

Gate valve
iii. Global Valve 

Global valve works via the reciprocating movement of a disc or plug. The disc or plug slides toward or away from the seat, either stopping or permitting fluid passage. The disc or plug is inserted into the valve seat. Therefore, it is detachable. Besides that, the pressure drop in the globe valve is significant. 

Global valve
iv. Check Valve

A check valve is used in piping systems to prevent backflow. The pressure of the fluid travelling through the pipeline causes the valve to open, Reverse flow prevents the fluid from flowing in the opposite direction by closing the valve. External control is not required for check valves. They operate automatically and hence lack an operating handle or stem. The most basic check valves have a one-way flap mechanism. 

Moreover, check valves are typically small, straightforward, and affordable. It is used in a variety of industrial applications, including feed water control systems, gas systems that combine various gases into a single gas stream, and fuel and oxidizer mixing systems. Also, they are frequently employed in household applications to avoid the mixing of a hygienic potable water supply with water from filthy systems. 

check valve
v. Needle Valve

A needle valve has a plug. The plug is tapered and fits snugly into the seat. Furthermore, the annular space between the tapered body of the plug and the seat controls the flow rate. It is also utilised for small, precise flows. The valve size ranges from 3mm to 25mm, and it can withstand temperatures and pressures of up to 260°C and 650 kg/cm respectively. 

Other than that, they are used to reduce pressure variations by controlling actuating air or hydraulic fluid. The needle valve can be made of bronze, brass, or stainless steel, among other materials.

vi. Butterfly Valve

The regulating element in a butterfly valve is a disc known as a blade, vane, or flapper, which rotates in a horizontal or vertical direction and permits fluid to flow, Throttling or on-off operation at modest pressure drop is possible with a butterfly valve. 

Besides that, it is inexpensive, simple to install, and prevents solids from accumulating. Also, butterfly valves can be screw-type or wafer-type. It can be operated manually, electrically, or automatically. Other than that, a butterfly valve of the water kind is depicted. It can be utilised for vacuum or pressure applications up to 80 kg/cm2. It is available in sizes ranging from 50mm to 900mm. The blade or flapper can be constructed or rubber, neoprene, or chloro sulphonated polyethylene and more.

vii. Safety Relief Valve 

The fundamental purpose of Safety Relief Valve is to protect people, property, and the environment. It is a safety device that protects a pressurised vessel or system from over-pressure if all other safety devices fail. It is intended to open and relieve excess pressure form vessels or equipment before closing and preventing additional fluid, gas, or steam discharge once normal conditions have been restored.

How are Valves in Piping Systems Classified?

Valve classification can be divided into various categories. They are classified according to function, working mechanism type, end connections, mechanical motion, construction material, pressure and temperature ratings, and port size. When selecting a valve, it is critical to analyse each of these classifications to ensure that the it is appropriate for the application. 

(A) Valve Function 

Valves are used in processes to perform a variety of purposes. They can be used to start and stop the flow as well as to adjust the flow and pressure. Also, they may be necessary to control the flow direction or to improve process safety. The types are classed based on flow control as isolation valves or regulation valves. 

       (I) Isolation valves

       Isolation valves are meant to either entirely limit or enable fluid flow without obstructing it. Hence, they should not used continuously in the partially open position because they may provide poor flow control or suffer wear damage over time.

       (II) Regulation valves 

         Regulation valves are used for precisely regulating pressure and fluid flow. They can be utilised in procedurres that require a partial open or closed state in a safe and efficient manner. 

           However, some valves can do both jobs, while others are only suggested for one. 

(B) Operating Mode 

Based on how they are manipulated, valves are classed as manual, actuated, or automatic.

        (I) Manual Valves

           Manual valves are usually actuated by hand using wheels, levers, pedals, knobs, or chains. They can be mechanically geared to change movement direction and/or improve operation speed or torque.

        (II) Actuated Valves

          Valves are frequently coupled to electric motors, pneumatic systems, hydraulic systems, or solenoids in high-precision or large scale applications to enable remote operation and automation of valve function. 

        (III) Automatic Valves 

           Some valves are actuated automatically when a certain flow condition is satisfied. During backflow, for example, check valves close without the need for external intervention. Similarly, when an over-pressure condition is identified, pressure release valves are engaged automatically. 

(C) End Connections 

Valves are joined to pipes by joints, which can be screwed, flanged, or welded. The following are some examples of common valves ends:  

  • Flanged end valves: A flange is a plate or ring at the end of a pipe or valve that forms a rim; two flanges are fastened together to form a connection. 
  • Screwed end valves: Screwed end valves feature threaded joints that are screwed to the end of a pipe or another fitting. 
  • Socket welded valves: The pipe is inserted and welded into a socket. 
  • Butt weld valves: The valves have beveled edges that correspond to a matching bevel on the pipe. 
  • Wafer type valves: The narrow valve body is located between two pipe flanges, with bolts around it. These valves are typically used on small-space systems.
(D) Mechanical Motion 

Valves are classed as Linear Motion Valves or Rotary Motion Valves based on the mechanical motion of the closing member. A linear motion valve is one in which the closing element of the valve moves in a straight line to allow or stop flow. A rotary motion valve is one in which the closing element rotates or moves in a circular path. 

Valves are also classed as multi-turn or quarter turn depending on how far the handle/wheel must be turned to completely open or close the valve. Rotary motion valves frequently require only a quarter turn (90°) of the stem to transition from completely open to fully closed.  

(E) Construction Material 

Depending on the intended temperature and pressure ratings, durability, and use, the valves body can be made of stainless steel, alloy steel, brass, cast iron, or plastics. To achieve the appropriate amount of seal and temperature/pressure ratings, the gasket, packaging, and valve seat are often composed of PTFE, ROM, FKM, PA, EPDM, or NBR. 

(F) Pressure-temperature ratings 

Valves can also be categorised based on their pressure and temperature specifications. These ratings describe the maximum permitted pressure and temperature levels that the valve may withstand safely.

Lap Joint Flange

Lap Joint Flange

Lap Joint Flange

The shape of a lap joint flange is similar to a slip on flange; it has a curved radius at the bore that can connect with a stub end fitting and slide over the pipe. The pipe is usually welded to the stub end so that it can freely rotate around the stub end. Lap joint flange and stub end assembly are primarily used in piping systems that must be dismantled frequently for inspection or routine maintenance. To reduce the overall cost of the connection, a stub end will often be made of a special material grade (nickel alloy), with the lap joint made of basic carbon or commodity stainless. Naturally, for uniformity, we recommend that both items be of the same grade. However, your application will determine what is best and/or necessary.

Advantages and Disadvantages 

The composite two-piece construction gives the lap joint flange two clear benefits when in operation. Imagine a lapped joint piping connection where all “wetted” sections must be made of a costly alloy (such as nickel, zirconium, tantalum, or titanium, etc.) to resist corrosion. The pricey, corrosion-resistant alloy can be used to create the stub end. Besides that, common carbon steels can be used to create the flange that serves as the backing flange. Therefore, it is less expensive than an entire alloy flange. On the other hand, it is not physically welded to the pipe. Hence, it may rotate easily to align bolt holes, making assembly and disassembly much simpler. Also, this make it easier to operate a piping system that must frequently be disassembled for inspection or standard maintenance. 

However, the use of the flange has several drawbacks. The flange bore’s internal surface and the stub ends’ external surface have produced fissures that can easily become contaminated. Moreover, the accumulated contaminants might be problematic and cause crevice corrosion. At the design temperature specified by ASME B31.3, the longitudinal strains brought on by pressure, weight, and thermal expansion may build up and surpass the fundamental allowed stress. As a result, it is often utilized in moderate service, where the strains placed on the flange connection by the pipe are minimal. It is because the material of the flange may differ from that of the stub end, galvanic corrosion may occur in some circumstances. 

Usage of Lap Joint Flange 

Typically, low pressure applications require for the usage of the flanges. Hence, it is not appropriate when the flange pair must support heavy weights, Moreover, it may be necessary for some pipes, such as a metal pipe that has previously been lined with plastic. 

Stub End – Key Fittings for Lap Joint Flange

A backing flange for a lap joint is always utilized with a stub end. Stub ends come in three main types: Type A, Type B, and Type C. 

Type A:

The typical lap joint support flange can be machined to accommodate the Type A stub end.

Type B:

The standard slip on flange is intended to be used with Type B stub ends. 

Type C:

The type C stub end can be utilized as either a slip on flange or a lap joint flange. 

Furthermore, stub end patterns can be extensive or short in length. Long pattern ends are also referred to as ASA Stub Ends. The shorter end is used with ANSI 300 and 600’s bigger flanges. They are frequently utilized in sizes ANSI 900 and higher. 

Lap Joint Flange

Differences Between Lap Joint flange and Slip On Flange 

In essence, a slip on flange is a ring that fitted over the pipe end. Additionally, the flange face must be far enough from the pipe’s end to allow for the application of a weld to the inner diameter. Moreover, the slip on flanges outside diameter can be welded to the backside of the flange. Slip on flanges cost less to make and are simpler to align than weld neck flanges. 

Besides that, slip on flange and lap joint flange are quite similar. Also, it almost seems identical from the outside which is the holes and sides of the lap joint flange. However, it has a curved radius on the reverse side to allow the lap joint stub end. On the other hand, the slip on flange can serve as the lap joint flange when type B or type C stub ends are utilized.

Threaded Flange

Threaded Flange

Threaded Flange

Threaded flange, also known as screwed flange, has a thread inside the flange bore that fits on the pipe with a matching male thread. This type of joint connection is quick and easy to use. However, threaded flange is not suitable for high pressure or temperature applications. Threaded flange is commonly used in utilities such as air and water. 

What is a Threaded Flange?

 

Threaded flange is similar to slip on flange except that the bore is threaded. It can be assembled without welding. This explains its use in low pressure services at normal atmospheric temperatures and in highly explosive areas where welding poses a risk. As the tapers approach the same diameter, the threads seal between the threaded flange and the pipe. In addition to the threaded connection,  a seal weld is sometimes used. 

Also, they are available in a variety of sized and materials. The thread must be concentric with the axis of the flange opening, and alignment variations (perpendicular to the flange face) must be not more than 5mm per metre. Threaded flanges are available in NPS 1/2 through NPS 24 sizes and pressure ratings of Class 150, 300, 400, 600, and 900. NPS 1/2 to NPS 2-1/2 are available in Class 1500 and Class 2500 sizes. 

Details of Threaded Flange
Connecting a pipe to the threaded flange
Key Characteristics of Threaded Flange 
 
  • No welding is required. 
  • Extremely good for small pipe sizes.
  • Larger load, especially when subjected to higher torque, should be avoided.
 
Uses of Threaded Flange 
 
  • Threaded flanges can be fitted to pipes of various sizes without welding. It is one of the main reasons why these flanges are so popular. 
  • It can be used in extremely high-pressure applications, particularly where post-weld heat treatment is not possible. 
  • It is ideal for piping with small diameters. 
  • Cost-effective and time-saving diameters. 
  • Threaded flanges are typically used in non-cyclic applications. 
  • The flanges can be used in applications where welding is dangerous. 
  • It can be used in potentially explosive environments. 
Details of Threaded Flange
Advantages & Disadvantages of Threaded Flange 
  • Advantages
    • The threaded flange joint does not require welding to be assembled. Also, a pipe with tapered threads on both ends can be easily assembled with the threaded flange. Because of this feature, the threaded flange is well-suited to extreme pressure services that operate at normal ambient temperatures. And also, in highly explosive areas where welding may pose a hazard.
  • Disadvantages
    • The disadvantages of threaded flanges are obvious as well. The crevices formed between the external and internal threads have the potential to easily capture and retain process fluid. This makes the threaded connection vulnerable to crevice corrosion. It occurs when process fluid penetrates the thread region and causes failure. Furthermore, threaded joints are also significant stress risers. A relatively small number of cycles of expansion and contraction or movement brought on by misalignment may cause the threaded flange to fail. This is because of tightening increases stress in the thread region.
    • Besides that, threaded steel flanges are typically limited to water or air services in sizes NPS 6 (DN 150) or smaller, with a design temperature of no more than 250 °F. They are also not suitable for high temperature, cyclic stress, or corrosive fluid conditions. The dimensional tolerances of threaded flanges are nearly identical to those of slip on flanges.

Socket Weld Flange

Socket Weld Flange

Socket Weld Flange

Socket weld flange is normally available with a raised face, a flat face, or an RTJ facing. When a raised face is required for socket weld flanges, the standard height for socket weld flanges under 400# is 1/16”. And the standard socket weld flange raised face height for 400# and higher socket weld pipe flanges is 1/4″.

Socket Weld Flange
What is a Socket Weld Flange?
 

Socket weld flange is commonly found on smaller diameter high pressure pipes. Inserting the pipe into the socket end and applying fillet weld around the top is how these pipe flanges are attached. This results in a smooth bore and improved flow of the fluid or gas inside the pipe. Furthermore, put on pipe flanges with hubs have published specifications ranging from 1/2” to 24”. Also, socket weld flange is available in a variety of material grades, specifications, and sizes.

Picture7
1 - Socket Weld Flange | 2 - Filled Weld | 3 - Pipe | X - Expansion Gap
Usage of Socket Weld Pipe
 

Pull back 1.6mm (1/16″) of the inserted pipe, put the pipe end into the socket weld flange until the pipe bottom touches the shoulder area, and then perform fillet welding. The goal is to weld a fillet to separate the flange from the pipes or fittings, leaving an expansion gap.

Features of Socket Weld Flange
 

A good fit of the pipe is made possible by the recess on the inside diameter of the socket weld flange, allowing for a smooth flow of liquid.

For smaller diameters and greater pressure/temperature settings, socket welding flanges are effective.

They are comparable to slip-on flanges, but they also have to state the schedule of the pipe they will be used with.

How Socket Weld Flange is Produced?
 

In order to prevent cracking faults brought on by thermal pressures during heating processes, the socket welding flange was initially employed for stainless steel superheaters. However, after years of development, it has become a regular application for all sorts of materials.

Types of Socket Welded Flange
 

Socket welded flanges, such as the raised face type and ring type joint type, are similar to other welding flange types (slip on, weld neck or blind flange).

Raised Face Type

A tiny piece of the RF Type RF socket weld flange projects from the face and surrounds the flange bore. This raised portion will house the gasket seat.

Ring Type Joint Type

There is an RTJ style groove on the raised face surface that you may fit a gasket ring in to improve sealing abilities.

Advantages of Socket Welded Flange
 
  • To reduce the possibility of leaking, socket weld flanges could take the place of threaded flanges.
  • Before welding, there is no need to bevel.
  • Outside of the pipe, welding work cannot enter the pipe bore.
  • Applications where interior welding operations are extremely challenging are advised to use it. Internal pockets are removed to the sock welding process. It is to prevent heat warpage and weld spatter damage to the flange face. 
  • It has a longer fatigue life and the same internal pressure as sliding on the flange.
 
 

Disadvantages of Socket Welded Flange

  • Socket welding needs more advanced welding abilities since the increasing space between the pipe and shoulder must be maintained at 1/16 inch during welding.
  • For anti-corrosive pipes like stainless steel pipes, the expansion gap increases the likelihood of crack flaws, therefore cracks between the pipe and flange will result in corrosive issues.
  • Socket Weld flange cannot be used in corrosive or radioactive environments. It is because of the risk of operating and maintenance issues associated with solid build-up at the junction. Hence, welding is used more frequently. It makes connections stronger and less susceptible to corrosion when it is done entirely through the pipe from the outside to the inside.
 
 

The Differences Between Socket Weld Flange & Slip On Flange

Slip On Flange

Socket weld flange is similar in shape to a slip-on flange; however, a socket-welded flange differs in having a shoulder at the inner bore.

Also, there is no shoulder at the inner bore for a slip-on flange.

Other than that, the static strength of a socket weld flange is the same as that of a slip-on flange, but its fatigue strength is 50% greater than that of a double-welded slip-on flange.

Weld Neck Flange

Weld neck flanges of Saliran Industrial Supplies Sdn Bhd

Weld Neck Flange

Weld neck flange is also known as a tapered hub flange or high-hub flange. Weld neck flange is a type of flange that can relocate stress to the pipes, resulting in a reduction in high-stress concentration at the flange’s bottom. There are two types of welding neck flanges: the first is used with wipes, while the second, longer type is used with process plants rather than pipes. Moreover, it is made up of a round fitting that extends beyond the circumference’s rim which allow the flanged to be attached to a bolted flange. Because of the structural valve, this design is far superior. And the flanges are easily identified by the long-tapered hub that gradually extends over to the wall thickness of a pipe or fitting.

Product Structure

 

Weld Neck Flanges are flanges that are designed to be buttwelded to a piping system. This type of flange includes numerous specifications. Besides that, the long-tapered hub serves as an important reinforcement in a variety of applications involving high pressure, sub-zero, and/or elevated temperatures. Also, under conditions of repeated bending caused by line expansion or other variable forces, the smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial.

It is also more expensive due to its long neck and the cost of people to connect the flange to the pipeline or fitting. However, it is preferred for high-stress applications. Moreover, the stresses are transmitted to the pipeline via the necks, or hubs. Furthermore, the gradual transition of thickness from the base of the hub to the wall thickness at the butt weld reinforces the flange.

Type of Weld Neck Flange

 

Weld neck flanges come in two shapes: one with a reducing neck, known as reducing weld neck flange, and one with an even diameter of a typical long neck, known as long neck weld flange.

i. Reducing Weld Neck Flange

As the name implies, it is a combination of a pipe reducer and a flange that can be welded directly to a smaller pipe.

ii. Long Weld Neck Flange
 

Long weld neck flanges are commonly found on vessel nozzles and equipment. Moreover, the flanges are made to fit the inside diameter of the pipe or fitting. Also, it is bored to match because it reduces the corrosion and turbulence that occurs inside the pipe.

Application of Weld Neck Flange

 

Welded neck flanges have a long-tapered hub and are frequently used in high-pressure applications. It is critical to specify the schedule pipe used when ordering a flange. This is due to the inside diameter of flange matching the inside diameter of your pipe. This flange’s buttweld joint with the pipe, combined with the tapered hub, makes it very resistant to dishing and a very sturdy connection. These flanges are ideal for extreme temperature fluctuations and environments where the flanges will be bent and handled frequently.

Advantages 

 

Weld neck flanges are appropriate for use in hostile environments with temperature, pressure, or other sources of stress. Also, this type of flange achieves resilience by sharing environmental stress with the pipe to which it is welded. Other than that, this flange has been used successfully at pressures as high as 5,000 psi.

On the other hand, its name from the flange’s neck, which is welded to the end of a piping system. Hence, it is intended to transfer stress to the pipe, reducing high stress concentrations at the flange’s base. By that, it is more expensive due to their design and engineering, as well as the increased material.

Carbon Steel Pipe

Carbon Steel pipes of Saliran Industrial Supplies Sdn Bhd

Carbon Steel Pipes

Carbon steel pipe is made of carbon steel which is an iron and carbon steel alloy that considered as a tough material. Carbon steel pipe is also the most widely used pipeline material for construction, structural, and liquid transmissions for water, oil, and gas. Hence, it is utilised in a wide range of heavy-duty industries. This including infrastructure, ships, distilleries, and chemical fertiliser equipment because of its strength and capacity to endure stress. Therefore, it must withstand the application’s pressure, temperature, and corrosion conditions. Furthermore, these requirements are met by using pipe manufactured in accordance with an ASTM or API standard. The standard grades of carbon steel pipe include API 5L Grade B, X42 to X70, ASTM A106 B, ASTM A53 B, ASTM A252 Grade 3, and ASTM A333 Grade 6, among others. 

Applications

 

Carbon steel pipes find numerous applications across various industries due to their strength, durability, and versatility. Here are some common applications:

Oil and Gas Industry: Carbon steel pipes are widely used in the oil and gas industry for transporting crude oil, natural gas, and petroleum products. They are preferred due to their ability to withstand high pressure and temperature conditions.

Water Transportation: Carbon steel pipes are extensively used for water transportation in municipal water supply systems, irrigation projects, and industrial water treatment plants. They offer corrosion resistance and can handle high flow rates.

Construction and Infrastructure: In construction projects, carbon steel pipes are used for structural support, piling, and underground utilities such as drainage systems and sewage lines. Their strength and durability make them suitable for heavy-duty applications.

HVAC Systems: Heating, ventilation, and air conditioning (HVAC) systems often utilize carbon steel pipes for distributing hot or cold water, steam, and air throughout buildings. These pipes offer thermal conductivity and are resistant to corrosion.

Industrial Applications: Carbon steel pipes are crucial in various industrial processes such as manufacturing, chemical processing, and power generation. They are used for conveying fluids, gases, and solids in piping systems within factories and plants.

Benefits 

 
Safe & Long lasting

Carbon steel pipe is both safe and long-lasting. It is an ideal material for structural applications. It is because it is shock resistant and unaffected by harsh environmental conditions such as pressure or extreme weather.

Cost-effective

Because of carbon steel’s incredible strength, carbon steel pipe can be made thinner and with less material while still transporting large volumes. As a result, it is a cost-effective material. 

Environmentally friendly

Furthermore, carbon steel is not only less expensive, but it is also recyclable. Hence, it is environmentally friendly and cost-effective.

Flexibility

Moreover, it is a versatile material because it is simple to manufacture. Therefore, it can be made in various thicknesses and sizes. Also, It is simple to cut and bend to fit wherever it is required.

Grade of steel used

 

Carbon steel pipe comes in a variety of grades and strengths, as well as wall thicknesses. As we have seen, the allowable stress is used to determine the required wall thickness. Hence, the allowable stress is determined by both the material’s metallurgy and the manufacturing method.

 
ASTM & API

Other than that, the various ASTM and API piping specifications provide guidelines for both metallurgy and manufacturing method. For example, ASTM Specifications A-53 and A-106, as well as API Standard 5L, are the most widely used piping specifications for process lines. 

Schedules

Also, the primary wall thicknesses used are defined by schedules, such as Schedule 40, and weights, such as STD. In Grades A and B, ASTM A53 and ASTM A106 pipe are fabricated SMLS or seamed by electric resistance welding. However, tensile strength is higher in grades B. Besides that, ASTM A106 is available in three grades, A, B, and C, in descending order of tensile strength.

Manufacturing Methods

 

There are numerous methods for producing carbon steel pipes, and each one results in a pipe with a unique set of properties. Strength, wall thickness, corrosion resistance, and restrictions on temperature and pressure are a few of these qualities. For instance, pipes with the same wall thickness but different manufacturing processes may have varying strengths and pressure limits.

Seamless pipe is created by piercing a solid, near-molten steel rod, known as a billet, with a mandrel, resulting in a pipe with no seams or joints. Figure 1.0 depicts the manufacturing process of seamless pipe.

Butt-welded pipe is made by passing hot steel plate through shapers, which roll it into a hollow circular shape. Forcing the two ends of the plate together will result in a fused joint or seam. Figure 2.0 shows the steel plate as it begins the process of forming a butt-welded pipe.

Spiral-welded pipe is the least common of the three methods. The spiral-welded pipe is made by twisting metal strips into a spiral shape, similar to a barber’s pole, and then welding the edges together to form a seam. Because of its thin walls, this type of pipe is limited to low-pressure piping systems. Figure 3.0 depicts spiral-welded pipe prior to welding.

Stainless Steel Pipe

Stainless steel pipe, composed of a nickel and chromium alloy, is commonly utilized in fluid or gas transportation systems due to its corrosion resistance, particularly against oxidation, making it suitable for high-temperature and chemical environments. Typically manufactured through welding or extrusion processes, welded pipes involve shaping steel and welding seams, while extrusion forms seamless products by heating steel rods and piercing them. Although often used interchangeably, “pipe” and “tube” have distinct measurements and purposes: pipes are measured by interior diameter for fluid and gas conveyance, while tubes, measured by outside diameter and wall thickness, are utilized in structural components and part construction.

Types of Stainless Steel Pipe

 
  • Seamless Pipe

A seamless pipe is one that contains no seams or weld joints. Because of the metal, it can withstand high levels of pressure as well as high temperatures. It is also used in numerous oil and gas applications. In addition, it is used in the mechanical and engineering industries. As a result, seamless pipes are extremely versatile, and they are always thoroughly inspected to ensure material quality.

  • Welded Pipe

Welded pipes can be found in almost any industry due to their versatility. They outperform in terms of corrosion resistance but not pressure resistance. Welded pipes, on the other hand, are far more cost-effective than most other piping methods. Because of the materials used and their lightweight nature, it may also provide the best value for money.

  • Flanges

Pipe flanges are another critical component of your overall piping setup. Slip-ons, blinds, lap joints, threaded, and semis are among the many styles available. To ensure dependability, these pipe flanges are made of durable and sturdy materials. They also make pipe flanges from high-quality materials.

  • Spectacle Blinds

People will usually use spectacle blinds, spades, and spacers  for temporary or long-term solutions that is allowed for the isolation of piping sections. If a piece of machinery or a section of piping needs to be inspected, spectacle blinds will be used to isolate a specific section of the piping. They will also maintain the overall system during the process. It is recommended that you rigorously test the dependability of your spectacle blinds to stay safe because it is such an important role that is critical to your safety. Because each case is different, it is advised that you consult with a professional before investing large sums of money in spectacle blinds.

Characteristics of Stainless Steel Pipe

  • Corrosion Resistance 

Almost all stainless steel pipes on the market are iron-based alloys with at least 10.5 percent chromium content. When chromium is present in an alloy, it forms a self-healing or protective oxide layer. Furthermore, the formation of an oxide layer contributes to the corrosion resistance of stainless steel pipes. Intact corrosion resistance can be achieved regardless of fabrication method due to the self-healing properties of the oxide layer. Even if the stainless steel pipe surface is damaged or cut, it can self-heal and has a high corrosion resistance. 

  • Work Intensification

One of the most significant benefits of work hardening stainless steel pipe grades is that it significantly increases and improves metal strength while also assisting in cold working. Aside from that, the combination of annealing and cold working stages is simple to use in order to provide adequate strength to fabricated components. Besides that, stainless steel pipe can self-heal and has a high corrosion resistance even if the pipe surface is damaged or cut. 

  • Strength and Formability

The strength of stainless steel pipe varies according to grade. In comparison to mild strength, strength remains somewhat constant in soft conditions. Austenitic steel, which is softer, has a high elongation and ductility. As a result, after a lengthy series of semi-fabrication, it can be cold worked to produce a finished product. Furthermore, toughness and strength must be effectively combined to achieve the desired result.

Ferritic stainless steel pipes are also extremely ductile and strong. Following heat treatment produces hardness and high strength in martensitic steel pipes.

  • Ductility

The percent elongation is responsible for ductility when performing a tensile test. The elongation of austenitic stainless steel is very high. The elongation of austenitic stainless steel is very high. Due to its high work hardening and ductility rates, austenitic stainless steel can form and work in a variety of processes, including deep drawing.

  • High Strength

Stainless steel pipe has a higher tensile strength than mild steel. Duplex stainless steel is generally stronger than austenitic steel. As a result, martensitic and precipitation hardening grades have the highest tensile strength. Furthermore, these grade types are twice as strong as other grades.

  • Magnetic Response

Magnetic response generally attracts stainless steel. Austenitic grades are purely nonmagnetic, though cold working can induce it in a few austenitic grades. Non-magnetic grades, on the other hand, such as 316 and 310, can be cold worked.

Types of Industry where Stainless Steel Pipe is Used

i. Oil and Gas

Technology is critical in the oil and gas industries. As the depths at which we search for oil have increased, so has the demand for corrosion-resistant piping. Hence, there will be more strain putting on the duplex and super duplex stainless steel pipes that we use. Corrosive environments can be extremely harmful. Besides that, if the damage is not repaired, the pipes will easily burst, rendering them unusable for deeper depths. Therefore, it is critical to have strong pipes in the oil and gas industry. 

ii. Nuclear Power

It is difficult to extract useful energy from atomic nuclei. Because of cooling requirements, the majority of today’s nuclear reactors are located near the coast. As a result, it will use much of the water to cool these reactors comes from the sea. And it must be corrosion resistant. Stainless steel pipe is critical in the nuclear power industry. This is because of its capable of resisting corrosion caused by seawater.

iii. LNG                                                                                                                      Liquefied natural gas (LNG) is natural gas that has been cooled to -260 degrees Fahrenheit. So, it can be safely transported to meet the growing demand for natural gas. Also, natural gas is not always feasible or cost-effective to transport via pipelines. So, it is instead transported in liquid form via cryogenic sea vessels and road tankers. As a result, having the proper piping in place to provide safe and cost-effective LNG transport to hard-to-reach areas of the country or the world is critical.

Benefits of Stainless Steel Pipe

Stainless steel is a highly adaptable material that can be used in a variety of indoor and outdoor applications. Using stainless steel pipe for your project has several benefits, including:

  • Lightweight
  • Durable
  • Long-lasting Capable of handling high flow rates
  • Simple to machine
  • Scratch resistance
  • Simple to clean
  • Low-maintenance
  • Outstanding corrosion resistance
  • Recyclable and eco-friendly material
