Seamless pipes made of ASTM A312 TP316/ TP316L shall be made by a process that does not involve welding at any stage of production; welded pipes shall be manufactured using an automatic welding process with no addition of filler metal during the welding process. The TP316/ TP316L pipe shall be heat treated by solution treatment, in which the pipe shall be heated and held for long enough period at a temperature no less than 1900°F [1040°C] so that all chromium carbides can be fully austenitized/ dissolved. Subsequent water cooling or rapid cooling by other means shall be conducted to ensure no precipitation of carbides at grain boundaries. Moreover, TP316L is less likely to precipitate chromium carbides compared to TP316 since their carbon content is low enough to reduce precipitation of intergranular carbides. This may result in limited sensitization hence benefit welding, flame cutting, and other hot-working operations.
