Classification of stainless steel pipes by production method:
(1) Seamless pipe—cold drawn pipe, extruded pipe, cold rolled pipe.
(2) Welded pipe
(A) Classification by process-gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(B) According to the welding seam-straight seam welded pipe, spiral welded pipe.
Stainless steel pipes are classified according to their cross-sectional shapes: (1) round steel pipes, and (2) rectangular pipes.
Stainless steel pipes are classified by wall thickness: thin-walled steel pipes, thick-walled steel pipes.
Stainless steel tube by application
(1) Civil pipes are divided into round pipes, rectangular pipes and flower pipes, which are generally used in decoration, construction, structure, etc .;
(2) Industrial pipe: Industrial piping steel pipe, general piping steel pipe (drinking water pipe), mechanical structure / fluid delivery pipe, boiler heat exchange pipe, food sanitary pipe, etc.
Stainless steel pipe is generally used in various fields of the industry such as: petrochemical, papermaking, nuclear energy, food, beverage, pharmaceutical and other industries that require higher fluid media.
