Stainless steel square tube is a kind of hollow long steel, because the cross section is square so called square tube. It is used in large quantities as a pipeline for transporting fluids, such as oil, gas, water, gas, steam, etc. In addition, it is lighter in weight when the bending and torsional strengths are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Stainless steel square tube classification: square tube is divided into two categories: seamless steel tubes and welded steel tubes (seamed tubes). According to the cross-sectional shape can be divided into square and rectangular tube.
For the stainless steel square tube subjected to fluid pressure are subjected to hydraulic pressure test to test its pressure resistance and quality, under the specified pressure does not occur leakage, wetting or swelling for qualified, some steel tubes also according to the standard or demand side requirements for rolled edge test, flaring test, flattening test, etc..
Square tube specification: 5*5~150*150 mm Thickness: 0.4~6.0 mm
Square tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S.
