304/304L Stainless Steel Welded Pipes are of two types ERW and EFW. A process for producing welded pipe is Electric Resistance Welding (ERW) also known as Contact Welding. Processing of Electric Fusion Welding, also called Continuous Welding begins as coiled steel with appropriate thickness, width and weight is made. SS 304/304L Welded Pipes are available in a wide range of sizes and properties. Due to the weld seam, lower operating pressures are stated in accordance with ASME compared to seamless pipes. In general Stainless Steel welded pipe possess tighter dimensional tolerances than seamless pipes and are less costly if produced in same quantities. Stainless Steel 304/304L Welded Pipe sizes range from 1/8" to 48" inches and the thickness of the pipes are as follows: Sch 5, Sch 5s, Sch 10, Sch 10s, Sch 20, Sch 30, Sch 40s, Sch 40, Sch STD, Sch 60, Sch 80s, Sch 100, Sch 120, Sch XS, Sch XXS, Sch 160. The Stainless Steel pipe is manufactured and finished according to dimension standards such as ANSI B36.10 and ANSI B36.19.
