Product Introduction

Stainless Steel 304 Round Tube

There are many kinds of stainless steel pipes, but the main ones have the following uses:
First, the classification of stainless steel pipes
1. Classified by production method:
(1) Seamless pipe - cold drawn pipe, extruded pipe, cold rolled pipe.
(2) Welded pipe:
(a) Classified by process - gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(b) According to the weld, straight seam welded pipe and spiral welded pipe.
2, according to the section shape classification: (1) round steel pipe; (2) Rectangular tube.
3, according to the wall thickness classification - thin wall steel pipe, thick wall steel pipe
4, classification by use: (1) civil pipe is divided into round pipe, rectangular pipe, flower pipe, generally used in decoration, construction, structure and other aspects;
(2) Industrial pipes: industrial distribution pipe steel pipe, general distribution pipe steel pipe (drinking water pipe), mechanical structure/fluid conveying pipe, boiler heat exchange pipe, food hygiene pipe, etc. Generally used in various fields of industry such as: petrochemical, paper, nuclear energy, food, beverage, medicine and other industries have higher requirements for fluid media pipelines.
