Welded Stainless Steel Pipe

Welded Stainless Steel Pipe

Welded Stainless Steel Pipes are manufactured by rolling stainless steel plates or strips and then welding them longitudinally using various processes such as ERW (Electric Resistance Welding) and EFW (Electric Fusion Welding). Available in sizes from 2″ to 48″ and in a wide range of schedules including 5S, 10S, STD, 40, 80, 160, and XXH, these pipes are widely used in industries where corrosion resistance, mechanical strength, and hygiene are critical.

Product Types and Applications:

This product range includes stainless steel welded pipes, ERW pipes, and EFW pipes, each tailored for specific applications. Welded stainless steel pipes are ideal for low to medium pressure systems in chemical processing, water treatment, construction, and food industries. ERW pipes offer precise dimensional control for structural and architectural use, while EFW pipes are suited for high-pressure applications, such as boilers and heat exchangers.

Material Grades and Selection:

Welded stainless steel pipes are available in a wide variety of grades, covering austenitic, ferritic, martensitic, and duplex stainless steels. Popular austenitic grades like 304/304L, 316/316L, and 321/321H offer excellent corrosion resistance and weldability. Ferritic grades such as 409, 430, and 444 are cost-effective and used in automotive and exhaust systems. For high strength and chemical resistance, duplex grades like 2205, S32750, and S32760 are the preferred choice in offshore and chemical plant environments.

Durability and Performance:

These pipes deliver excellent strength, corrosion resistance, and pressure handling, with enhanced durability under both ambient and high-temperature conditions. Thanks to advanced welding technology and precision forming, they maintain a uniform wall thickness and smooth internal surfaces, which are essential for maintaining flow efficiency and cleanliness in sanitary and process applications.

Versatility and Industry Compliance:

Compliant with international standards and specifications, welded stainless steel pipes are a trusted solution for plumbing, HVAC, marine, oil and gas, and pharmaceutical industries. Their availability in various sizes, wall thicknesses, and finishes—along with their customizable nature—makes them an essential component across many critical infrastructure and industrial systems.
