711079 Stainless Steel Pipes SCH 40 SUS 304 Stainless steel pipes are divided into seamless pipes and welded pipes according to production methods. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold drawn pipes, and extruded pipes. Cold drawing and cold rolling are the second type of steel pipes. Processing; Welded pipes are divided into straight seam welded pipes and spiral welded pipes.

Product Introduction

Stainless steel pipe and tube

Classification of stainless steel square pipes: Square pipes are divided into two categories: seamless steel pipes and welded steel pipes (seam pipes). According to the cross-sectional shape, it can be divided into square tubes and rectangular tubes. Circular steel pipes are widely used, but there are also some irregular steel pipes, such as semi-circular, hexagonal, equilateral triangle, octagonal, etc.
For stainless steel square pipes that withstand fluid pressure, hydraulic tests must be conducted to verify their pressure resistance and quality. They are qualified if they do not leak, wet, or expand under the specified pressure. Some steel pipes must be rolled according to standards or the requirements of the demand side. Edge test, expansion test, flattening test, etc.
