Stainless Steel square tube classification: the square tube is divided into Seamless Steel Pipe and Welded Steel Pipe (seam pipe). According to the shape of the section, it can be divided into square and rectangular tubes. Round steel tubes are widely used, but there are also some semi-circular, hexagonal, equilateral triangle, octagonal, and other special-shaped steel tubes. For stainless steel square pipes that are subjected to fluid pressure, hydraulic tests are required to check their pressure resistance and quality. No leakage, wetting, or expansion under the specified pressure is qualified. Some steel pipes are also rolled according to standards or demander requirements Side test, flaring test, flattening test, etc.
