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.
