stainless steel rectangular tube

  The stainless rectangular steel tube is a hollow strip of steel with a rectangular section, so it is called a rectangular tube, which is widely used as a scaffold frame structure, such as petroleum, natural gas, water, gas, steam, etc., in addition, when bending and torsional strength are the same, Light weight, so also widely used in the manufacture of mechanical parts and engineering structures. Also used in the production of a variety of conventional weapons, guns, artillery shells and so on.

  1.Classification of stainless steel rectangular tubes

  Stainless steel moment pipe is divided into seamless steel pipe and welded steel pipe (slit pipe) two categories. According to the shape of section can be divided into rectangular tube and square tube, square pipe is widely used, but there are also some special-shaped steel pipe.

  Hydraulic tests are carried out to test the pressure resistance and quality of steel pipes subjected to fluid pressure. There is no leakage under specified pressure and soaking or expansion is qualified. Some steel pipes are also required to carry out crimping tests in accordance with the standards or requirements of the demand party. Flaring test, flattening test, etc.

  Stainless steel tube is made from steel ingot or solid tube billet through perforation, then hot rolled, cold rolled or cold drawn. The specification of stainless steel tube is expressed by the number of millimeters of side length * wall thickness.

  2.Material of stainless Steel rectangular Tube

  304 stainless steel tube

  SUS304 stainless steel pipe belongs to American grade stainless steel pipe. Domestic grade is equivalent to 0Cr19Ni9 stainless steel pipe, which is usually replaced by 0Cr18Ni9.

  The antirust mechanism of stainless steel is that the alloy elements form dense oxide film to insulate oxygen contact and prevent further oxidation. So stainless steel is not stainless.

  3.Production Technology of stainless Steel rectangular Tube

  Stainless steel tube (seamless pipe)

  Round steel preparation b.heating, hot rolling and piercing, Cutting head, pickling, grinding, lubrication, cold rolling, processing, degreasing, heat treatment, straightening, pipe cutting, pickling, pickling; Finished product inspection.

  4.Application of stainless Steel rectangular Tube

stainless steel rectangular tube

  Stainless steel tubes are used in some shallow drawing products. Such as shallow processing pot, indoor staircase handrails, elevators, mirror surface, wire surface and other surface processing products. Door and window guardrail, security window all kinds of support.
