The stainless steel square tube is a hollow, long strip of steel, which is called a square tube because of its square cross-section.

 

application:

 

A large number of pipelines are used to transport fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, they are lighter when the bending and torsion strength are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures.

 

Stainless steel square tube classification:

 

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 and rectangular pipes. Round steel pipes are widely used, but there are also some special-shaped steel pipes such as semicircle, hexagon, equilateral triangle, octagon and so on.

 

Square tube specifications:

 

5*5~150*150 mm thickness: 0.4~6.0 mm

 

Square tube material:

 

304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S.

 

Production Process:

 

Round steel preparation → heating → hot rolling piercing → cutting head → pickling → grinding → lubrication → cold rolling processing → degreasing → solution heat treatment → straightening → pipe cutting → pickling → finished product inspection.
