ASME SA312 Stainless Steel Pipes

ASME SA312 Stainless Steel Pipes

ASME SA312/SA312M is a specification for seamless pipes, straight-seam welded pipes and heavily cold worked welded austenitic stainless steel pipe, and all pipes will be intended for high-tempera

ASME SA312/SA312M is a specification for seamless pipes, straight-seam welded pipes and heavily cold worked welded austenitic stainless steel pipe, and all pipes will be intended for high-temperature and general corrosive service. 


How to manufacture stainless pipes understand ASME SA312/SA312M:

The pipes under this standard should be manufactured by one of the following process:

* Seamless (SML) Pipe: it should be made by a process that does not involve welding at any stage of production.

* Welded (WLD) Pipe: it should be made using an automatic welding process with no additional of filler metal during the welding process.

* Heavily Cold-Worked (HCW) Pipe: it should be made by applying cold working of not less than 35% reduction in thickness of both wall and weld to a welded pipe prior to the final anneal. No filler should be used in making the weld. Prior to cold working, the weld should be 100% radio-graphically inspected in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, latest revision, Paragraph UW-51.
