Stainless steel square tube is a hollow strip of steel, because the cross-section is square so called square tube. A large number of pipelines used to transport fluids, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsional strength at the same time, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Stainless steel square pipe classification: square pipe is divided into seamless steel pipe and welded steel pipe (welded pipe) two categories. According to the section shape can be divided into square and rectangular pipe, widely used is round steel pipe, but there are also some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel pipe.
For the stainless steel square pipe under fluid pressure, hydraulic tests should be carried out to test its pressure resistance and quality, and no leakage, wetting or expansion under the specified pressure is qualified, and some steel pipes should also be crimping test, flaring test, flattening test, etc., according to standards or requirements of the demander.
