ASTM A312M (in ASTM A999M) requires a welded stainless steel pipe to be straight to within 3.2 mm over 3.0 m lengths. Generally, the thumb rule is that 1 mm per meter is acceptable. However, most purchasers clearly specified a maximum acceptable limit for straightness. Pipe Inspection,Testing & Marking Requirements to Ensure ASTM A312M (in ASTM A999M) requires a welded stainless steel pipe to be straight to within 3.2 mm over 3.0 m lengths. Generally, the thumb rule is that 1 mm per meter is acceptable. However, most purchasers clearly specified a maximum acceptable limit for straightness. Pipe Manufacturing Process / Methods for Seamless & A welded pipe can be manufactured in large sizes without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric

Stainless Steels Welding Guide - Lincoln Electricstainless steel is generally helpful in welding. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher. Stainless steels which require special welding procedures are discussed in later sections
