Stainless Steel Welded and ERW Pipe Manufacturer in India

Top notch supplier of Stainless Steel EFW Pipe, Check ASTM A312 SS Welded Pipe Dimensions & Weight charts

Stainless Steel Welded Pipe is a pipe that is made up of stainless steel and is produced by welding procedure. There are different types of stainless steel such as austenitic, ferritic, martensitic and duplex. These pipes have different crystalline structures and different mechanical properties. The welded pipes can be produced by different procedures. Roopam Steel is a leading supplier and manufacturer of Stainless steel welded pipes and we offer all different types. The Stainless Steel ERW Pipe is made up of a process called electric resistance weld. The process is performed by applying electricity to the stainless steel strip or plate to melt it at the joining points and then weld them together to form the pipe.

There are Stainless Steel EFW Pipe types that are made up of a procedure known as electric fusion welding. Similar to electric resistance weld but the EFW process involves an electric arc, instead of electric resistance heating. The EFW process is used with large diameter pipes and it welds the plates longitudinally with the electric arc to melt and weld the pipes. There are different shapes to the pipes as well. The SS Welded Square Pipe, hexagonal pipe and rectangular pipes are some of the shapes. But the round pipes are the ones used most commonly. There are different specifications such as the ASTM A312 Welded Pipe which covers high temperature service pipes. Are you looking for Stainless Steel ERW Pipe Manufacturer In India.
