Forged Fittings

Forged fittings, unlike butt weld fittings, are utilized for connecting small diameter piping systems through branches, blinds, or routing. They are crafted through forging and machining processes and adhere to standards such as ASME B16.11, MSS-SP-83, SP95, SP97, and BS3799. Available in sizes ranging from 1/8″ to 4″, these fittings are typically made of carbon steel A105 or stainless steel SS316. Named for the forging process used in their production, they are robust options suitable for nominal bore pipes. Offered in both socket weld and threaded configurations, they are constructed from materials like A105 carbon steel, stainless steel, and nickel alloy, making them suitable for various pipe fitting applications. With pressure classes ranging from 2000# to 9000#, they are designed for demanding applications.

What Are Forged Fittings?

Forged fittings are used to connect. branch, blind, or route piping systems with small diameters. Unlike butt weld fiittings, which are made of pipes and plates, forged fittings are made of forging and machining. Also, forged fittings are available in accordance with the standards and specifications of ASME B16.11, MSS-SP-83, SP95, SP97, and BS3799. All of these forged fittings can be used to connect nominal bore pipes. Moreover, they are made of carbon steel A105 and stainless steel SS316. These forged fittings range in size from 1/8″ to 4″. Furthermore, these fittings got their name from the forging process used in their production. The raw material, which is steel alloy or carbon alloy, is heated and formed into a customizable shape during the manufacturing of these fittings.

Besides that, forged fittings are available in both socket weld and threaded configurations. Additionally, these forged fittings are constructed with A105 carbon steel, stainless steel, and even nickel alloy. And all of these raw materials are suitable for the production of pipe fittings. Additionally, forged fittings are heavier, thicker, and designed for use in more demanding applications. Hence, these pipe fittings have pressure classes of 2000#, 3000#, 6000#, and 9000#.

The Various Types of Forged Fittings

There are various types of forged fittings available on the market. For example, 90D elbow, 45D elbow, straight coupling, three-piece union, and three-way tee are among the fitting types. Besides that, end cap, end plug, hex nipple is also available.

Therefore, a three-way tee is arranged in a T shape with one inlet and two outlets. On the other hand, the forged fittings are useful for combining the flow from two channels to a single outlet. In this case, the reducer assists the system in significantly reducing the flow size to a smaller direction.

Manufacturing of Forged Pipe Fittings

Manufacturers adhere to specific standard procedures and norms when producing each marked pipe fitting. Therefore, every forged fitting has a permanent marking on the collar part with the required credentials. Also, the goal of this marking is to keep the user informed while identifying pipe fitting specifications. Other than that, it also allows for the smooth operation of purchase and selection procedures. Furthermore, every forged pipe fitting reflects various marks. For example, the manufacturer’s trademark, the country of origin, the standards, the size, the work pressure capacity, the material, and the pressure.

Characteristics of Forged Steel Fittings

Strong and long-lasting

Steel forged fittings have a higher overall strength and toughness than steel processed in other ways. Besides that, forged steel is less likely to shatter when in contact with other objects, making it ideal for items such as swords. This increased strength and durability is due to how the steel is forced into shape during the forging process — by pressing or hammering. In addition, this process stretches the grain of the steel, causing it to be aligned in one direction rather than being random. Also, the forging is cooled in water or oil after pressing or hammering. Therefore, the steel is stronger than if it had been cast by the end of the process.

The consistency of forgings

As forged steel fittings is a controlled and deliberate process, with each forging going through the same steps. Hence, it is usually possible to ensure a consistent material over the course of many different forgings. Cast steel, on the other hand, is more random in nature due to the processes used.

Size Restriction

It is more difficult to shape the metal during the forging process. This is because forging occurs while the steel is still solid, as opposed to casting, where the metal is reduced to its liquid form as part of the process. As the metallurgist working with the steel will have more difficulty changing the metal’s shape, the size and thickness of the steel that can be successfully forged are limited. Thus, the larger the metal section under consideration, the more difficult it is to forge.

No Comments on Butt Weld Fittings

Butt Weld Fittings

Butt weld fittings play a crucial role in piping systems by facilitating seamless connections between pipes or tubes. Unlike threaded or socket weld fittings, they are welded directly to the pipe end, ensuring a robust and leak-proof joint. Commonly used in industrial settings, such as oil and gas, chemical processing, and power generation, butt weld fittings come in diverse shapes and sizes to accommodate various requirements. Their design minimizes turbulence and pressure drop, enhancing the efficiency of fluid transportation systems. They offer reliability, structural integrity, and ease of installation, making them indispensable components in piping and fabrication projects.

What are Butt Weld Fittings?

Butt weld fittings are weldable pipe fittings that allow you to change the flow direction, branch off, reduce pipe size, or attach auxiliary equipment. Furthermore, butt weld fittings made of forged steel are manufactured in accordance with ANSI / ASME B16.9. Butt weld fittings are the most common type of welded pipe fitting, and their nominal pipe size and pipe schedule are specified. Besides that, butt weld fittings begin with seamless or welded pipe and are formed (via multiple processes) into the shapes of elbows, tees, and reducers, among other things. Butt weld fittings are more common in stainless steel because of the cost savings.

Also, butt weld fittings are known as welded pipe fittings. These fittings can provide certain advantages over socket weld and threaded fittings while using in stainless steel and carbon steel. Whereas socket weld fittings are only available up to a certain size, butt weld fittings are available in sizes ranging from 1/2 inch to 72 inch.

Types of Butt Weld Fittings

Butt weld 45° Elbow Fittings

45-degree elbow with a long radius (1.5 x Diameter) and a 45 degree change in fluid direction.

Butt weld 90° Elbow Fittings

90-degree steel pipe elbow with long radius (1.5 x Diameter).

Butt weld 180° return bend Fittings

More than a 90-degree elbow is referred to as a steel bend. For example, long radius and short radius 180-degree bends.

Other than that, butt weld elbow dimensions can be specified as diameter (in NPS) and thickness (in schedule 40 or schedule 80) according to ANSI. For instance, long radius 90-degree elbow 4 inch and thickness in schedule 40 or schedule 80.

Butt Weld Tee Fittings

The vacuum tubing on all three ports of butt weld tee fittings is the same diameter. Hence, tees are commonly used in vacuum piping systems to provide a 90-degree branch.

Butt Weld Reducer Fittings

Reducer is a pipeline component. It can reduce the size of the pipeline from large to small bore based on the inner diameter. Therefore, the length of the reduction is equal to the average of the smaller and larger pipe diameters. Moreover, you can also use the reducer as a diffuser or nozzle in this case.

Butt Weld Cap Fittings

To close off the end of a pipe, a cap will be applied. Hence, the end caps are used to seal or block off the end of a pipeline. Also, the end cap is welded to the relevant sized pipe within the pipeline that requires blocking off or sealing at the weld prep. Unlike a blind flange, which can be unbolted to allow access to the pipeline, the end cap is permanently attached once installed.

How are Butt Weld Fittings Made?

Hot forming would be used to create this type of pipe fitting. By that, it would entail bending the pipe and shaping it into a shape. After that, the manufacturer will cut the pipe to length and that pipe will be the starting material of this fitting. Then, this pipe would be heated and moulded into specific shapes using dies. Also, the heat treatment would be performed to achieve the desired mechanical properties and remove residual stresses.

The Advantages of Butt Weld Fittings

Inexpensive and simple to use.
It can reduce corrosion action and frictional resistance.
Welded joints offer more design flexibility and take up less space.
It is usually permanently leakproof for a welding fitting connection.
Butt weld fittings are continuous metal structure that connects a pipe and a fitting and has a high strength performance in a piping system.
The connection has a smooth inner surface and changes direction gradually. The pressure losses and turbulence for fluid transport will then be reduced.

What is the Difference Between Short Radius (SR) and Long Radius (LR)?

The terms SR45 elbow and LR45 elbow are frequently used. And the 45 or 90 refers to the bend angle for buttweld fitting to change the flow direction. Apart from that, a long radius elbow (LR 90 Elbow or LR 45 Elbow) has a pipe bend that is 1.5 times the pipe size. As a result, a 6-inch LR 90 has a bending radius that is 1.5 times the nominal pipe size. Also, a short radius elbow (SR45 or SR90) has a pipe bend equal to the size of the fitting. So, a 6″ SR 45 has a bending radius equal to the nominal pipe size of 6″.

SLIP ON FLANGE

No Comments on SLIP ON FLANGE

Slip On Flange

Slip on flange are also known as SO flange. It is widely known due to its low material cost and ease of installation. There are many different diameters as well as low-pressure models to choose between. Slip on flange, apart from welding neck flanges, lacks a neck to rest on the pipe, necessitating double welding. A slip-on flange is a type of flange that is designed to slip over the end of a pipe and then be welded in place. It has a slightly larger inside diameter than the outside diameter of the pipe it is intended to be used with. This allows the flange to slide over the pipe, and then the pipe and flange are welded together.

How Does A Slip On Flange Work?

Slip on flange are designed to fit over pipes and are slightly larger inside than pipe. They connect to the pipe via a fillet weld at the top and bottom of the flange. In addition, it is used to insert the pipe into the flange’s inner hole. It is because the flange’s inner diameter is slightly larger than the pipe’s outer diameter. Hence, the pipe and flange can be joined by lap welding at the top and bottom of the flange.

Accordingly, it lacks a weld bevel, hence it is a simple and excellent alternative to a weld neck, allowing the pipe to be adjusted in length relative to the flange’s position. Other than that, the flange’s bore will provide plenty of room for the matching pipe. By that, it provides enough working space for the welder and fabricator to connect.

Besides that, it is very common in low-pressure applications. Most of the flanges would have a hub that looks dimensionally similar to a raised face. If space is tight and also the application enables for a “ring style” slip on, it could be furnished without a hub. Even though the hub style seems to be more usual when referring to a slip on, a ring style slip on without a hub is still considered a slip on flange. In order to have a better connection, the flanges in higher pressure classes are frequently made with the height of a lap joint.

Types of Slip On Flanges

While slip-on flanges primarily serve the function of connecting pipes in a piping system, they come in various types to suit different needs and applications. Here are some common types of slip-on flanges:

Raised Face Slip-On Flange: This type of slip-on flange has a raised face around the bore hole, which serves as a mating surface for the gasket. The raised face helps create a tighter seal between the flange and the mating component, reducing the risk of leaks.
Flat Face Slip-On Flange: Unlike the raised face flange, a flat face slip-on flange has a flat surface without any raised area around the bore hole. It requires the use of a flat gasket and is typically used in applications where a raised face is not necessary or desired.
Ring Type Joint (RTJ) Slip-On Flange: RTJ slip-on flanges feature a groove machined into the flange face to accommodate a metal ring gasket. These flanges are commonly used in high-pressure and high-temperature applications where a reliable and leak-proof seal is required.
Male and Female Slip-On Flange: In this type, one flange has a raised face while the mating flange has a corresponding depression or female face. The raised face fits into the depression, providing a more secure fit and alignment between the flanges

No Comments on Blind Flange

Blind Flange

A blind flange is also known as a solid flange. Blind flange is primarily designed to cap off a line. It is also designed to cover a pipe or nozzle on a vessel that is not being utilised. In addition, a nozzle is normally a pipe that exits a container which is flanged. By that, it can be attached to valves or pipework. A nozzle is frequently blocked off from a blind flange for load tests in a plant or just because the customer doesn’t use all the nozzles that were provided on the tank. Other blind flanges are made of simple materials, need little machining in comparison to other flanges. Furthermore, blind flanges are weight more than most alternatives since they lack a bore. Other than that, we also offer custom machined parts to match up to slip-on and weld neck flanges. NPT threads in the middle and custom bore holes are common modifications. Blinds can also be provided with high hubs (most API 6BX blinds have high hubs as a requirement).

Where are Blind Flanges Most Commonly Used?

In general, the blind flange can have a raised face, a ring joint face, or a flat face. If it has a raised face, we would propose a standard ring gasket suitable for the servicing and/or test. The most common reason a flange may be flat faced is because it was not built to withstand the bending pressures that would come from using a ring gasket or raised face flange.

Also, the blind flange is being used to blank off the end of piping, valves, and pressure vessel openings, similar to a plug or cap. It can be made of cast iron, forgings, specific plates, or flat bars. Unlike a welded cap, the blind flange allows easy access to the inner of a vessel or pipe because it is bolted. Besides that, they are the most stressed of all standard flange types in addition to the internal pressure as well as bolt loading, especially in large sizes.

Benefits of choosing Blind Flanges

Blind flanges are crucial components in pipelines, offering several benefits:

Closure and Isolation: One of the primary functions of a blind flange is to seal off the end of a pipeline. This prevents the flow of fluids or gases through that particular section, allowing for maintenance, repairs, or inspections to be carried out downstream without affecting other parts of the pipeline.

Safety: By providing a secure closure, blind flanges enhance safety by minimizing the risk of leaks, spills, or accidents during maintenance activities or shutdowns. This is particularly important in industries dealing with hazardous materials or volatile substances.

Pressure Testing: Blind flanges are often used during pressure testing of pipelines. By closing off the end of the pipeline with a blind flange, pressure can be applied to the system to check for any leaks or weaknesses in the piping infrastructure before it is put into service.

Temporary Blockage: In situations where a section of the pipeline needs to be temporarily blocked off, such as for maintenance work or equipment installation, blind flanges can be quickly installed and removed as needed, providing a temporary blockage solution without the need for permanent modifications to the pipeline.

Flexibility and Versatility: Blind flanges come in various sizes, materials, and pressure ratings, making them versatile components suitable for a wide range of pipeline applications. They can be customized to meet specific project requirements, ensuring compatibility with different pipeline systems.

Corrosion Resistance: Depending on the material chosen for construction, blind flanges can offer excellent corrosion resistance, prolonging the service life of the pipeline and minimizing the need for frequent replacements or repairs.

Cost-Effectiveness: Compared to other closure methods, such as welding caps or plugs, blind flanges offer a cost-effective solution for pipeline closure and isolation. They can be easily installed and removed without requiring specialized equipment or labor-intensive procedures, reducing downtime and associated costs.

Standardization: Blind flanges are manufactured according to industry standards such as ASME B16.5 or API 605, ensuring compatibility and interchangeability with other pipeline components. This standardization simplifies procurement, installation, and maintenance processes, streamlining operations for pipeline operators.

Type of Instrument valve: Function and Basic

1. What is Instrument valve?

Instrument measurement shows up in applications that require valves. These applications include static pressure, isolation, differential pressure, Venting, liquid level, gauge pressure and instrument lines. In addition, at the end connection of valves, female NPT & Male NPT can be found.

2. Different type of Instrument valve

Hand Valve

The existing of hand valve control the amount of inlet steam nozzles to be used while operating. TESCOM Anderson Greenwood Instrumentation hand valves are suitable for all instrument isolation duties, helping provide bubble tight shut-off time after time. Also, with metal or soft seats for gas, vapor or liquid applications, rated up to 10,000 psig (690 barg), there is a hand valve for even the most severe service. It is available in standard or exotic materials.

No Comments on Difference between Seamless and Welded Pipe

Differences between Seamless pipe and Welded pipe

Seamless and Welded pipe are the most prominent comparison among different types of piping techniques. To differentiate Seamless and Welded pipe, many factors should take into accounts from Manufacturing process, Length and Size, Working Pressure and Corrosion Resistance, Material Availability and Lead Time until economy and testing.

Seamless Pipe VS Welded Pipe

1. Manufacturing Process

Seamless pipe are derived from large piece of solid cylindrical steel, known as billet which is then heated and stretched until it forms into a hallow tube with desired dimensions.
Welded Pipe are manufactured from a long-coiled strip, known as skelp which is then rolled by a bending machine until it formed into a tube with desired dimensions. Welding pipe available in a few types such as ERW, SSAW, LSAW, DSAW.

2. Length and size

Due to the difficulties in manufacturing process, Seamless pipe is relatively shorter. Generally, Seamless pipe is produces in nominal sizes from 1/8” to 36”
On the other way round, welded pipe does not have any length and size limitation. Hence, in terms of length and size availability, welded pipe is better.

3. Working Pressure and Corrosion Resistance

“Seamless” pipe which named as no seam (crease) or welded joint found, caused a higher working pressure compared to welded pipe. Absent of seam allowed seamless pipe to resist more pressure and load. Hence, corrosion resistance is higher.
Conversely, “Welded” pipe which consist of seam due to welding has 20% lower working pressure. Hence, resulting a lower corrosion resistance.

4. Material Availability and Lead Time

The manufacturing of seamless pipe required limited high strength material such as stainless steel, copper, carbon steel, titanium, Monel, Hastelloy, etc. Limited Materials and complex production process caused a longer lead time.
On the contrary, manufacturing of welded pipe made by long coiled strip which available in various different material. Hence, shorter delivery and lead time required.

5. Economy and Testing

Seamless pipe does not require weld integrity test. However, the complexity of manufacturing process had caused a high costing.
Conversely, welded pipe is more economic. It must be tested before use to build a piping system.
