What is a welded pipe?
A welded pipe is made of long ribbon steel known as “skelp”. Skelp is cut into a flat rectangular sheet with a specific length. The rectangular sheet is then undergoing the ERW process where a rolling machine curls the long side towards one another. A cylinder is formed as a high-frequency voltage pass through the cylinder, resulting in it melting and fusing together. Welded pipes are customized to meet an extensive range of application requirements such as material grades and pressure.

Different of stainless steel welded pipe and carbon steel welded pipe
Stainless steel welded pipes and carbon steel welded pipes differ primarily in their composition, corrosion resistance, and intended applications. Here are some key distinctions between the two:
- Composition:
Stainless Steel Welded Pipe is made from an alloy of iron with a minimum of 10.5% chromium content. Other alloying elements, such as nickel, molybdenum, and titanium, may also be present. The chromium content provides corrosion resistance and gives stainless steel its characteristic shine. Carbon steel is an alloy of iron with carbon content ranging from 0.05% to 2.0%. The carbon content gives carbon steel its strength but makes it more susceptible to corrosion compared to stainless steel.
- Corrosion Resistance:
Stainless Steel Welded Pipe is known for its excellent corrosion resistance, especially against rust and staining. This makes it suitable for applications where resistance to corrosion is crucial, such as in the chemical, petrochemical, and food processing industries. Carbon Steel Welded Pipe is stronger than stainless steel welded pipe, it is more susceptible to corrosion compared to stainless steel. Protective coatings or treatments are often applied to carbon steel pipes for certain applications, but they may still require more maintenance to prevent corrosion.
- Applications:
Stainless Steel Welded Pipe is widely used in industries where corrosion resistance is essential, such as chemical processing, oil and gas, food processing, pharmaceuticals, and construction. Stainless steel pipes are also common in applications where hygiene and cleanliness are critical. Carbon Steel Welded Pipe is commonly used in applications where strength and durability are the primary considerations, such as in the construction of buildings, bridges, and pipelines for the transportation of non-corrosive fluids. Carbon steel pipes are often more cost-effective than stainless steel pipes.
- Cost:
Typically Stainless Steel Welded Pipe is more expensive than carbon steel due to the higher cost of alloying elements, especially chromium and nickel. Generally Carbon Steel Welded Pipe is more cost-effective than stainless steel, making it a popular choice for a wide range of applications.
Welded pipes applications
Welded pipes serve pivotal roles across industries, prominently in oil and gas pipelines, water and sewer systems, construction for building frames and supports, and the automotive sector for exhaust systems. In chemical processing, they’re crucial for their corrosion resistance, while the agricultural field employs them in irrigation and drainage systems. Additionally, welded pipes find application in mining, energy production, shipbuilding, and the food and beverage industry due to their durability and hygiene. Their versatile use extends to the pulp and paper industry for fluid transport. In essence, welded pipes are integral for fluid and gas conveyance in a wide array of sectors.
