201 large diameter stainless steel pipe Astm 201 stainless steel square pipe tube

Stainless steel pipe according to the production mode is divided into seamless pipe and welded pipe two

categories, seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and

extrusion pipe, cold drawn, cold rolling is the secondary processing of steel pipe;The welded pipe is

divided into straight seam welded pipe and spiral welded pipe.
