Stainless steel rectangular tube is a kind of hollow long steel, which is used as a pipeline for conveying fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so It is also widely used in the manufacture of mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.

Steel pipes are divided into two categories: seamless steel pipes and welded steel pipes (with seam pipes). According to the shape of the section, it can be divided into round tubes and special-shaped tubes. Circular steel tubes are widely used, but there are also some special-shaped steel tubes such as square, rectangular, semi-circular, hexagonal, equilateral triangle and octagonal.

For steel pipes subjected to fluid pressure, hydraulic tests are carried out to check the pressure resistance and quality. No leakage, wetting or expansion is allowed under the specified pressure. Some steel pipes are also subjected to the crimping test according to the standard or the requirements of the purchaser. , flare test, flattening test, etc.

Seamless stainless steel pipe is also called stainless steel seamless pipe. It is made of steel ingot or solid pipe blank through perforation and then made by hot rolling, cold rolling or cold drawing. The specifications of the seamless steel pipe are expressed by the outer diameter * wall thickness in millimeters.

Third Party inspection that is preferred by new customers is proved to be convincing. Through years of operation, M/S Ruicheng Steel has established stable contact with world famous third party inspection authorities, like Lloyd’s, BV, SGS, ABS, Intertek, etc. More than 10,000Mtons of steel pipes, tubes, fittings and flanges have been inspected by them.
