What is a stainless steel square tube?
Stainless steel square tube is a kind of hollow long steel. Because the section is square, it is called square tube. A large number of pipelines are used to transport fluids, such as oil, natural gas, water, gas, steam, etc. in addition, when the bending and torsional strength are the same, the weight is relatively light, so they are also widely used in the manufacture of mechanical parts and engineering structures.
Classification of stainless steel square tubes
Stainless steel square pipe is divided into seamless steel pipe and welded steel pipe (slotted pipe). According to the section shape, it can be divided into square and rectangular pipes. Circular steel pipes are widely used, but there are also some special-shaped steel pipes such as semicircular, hexagonal, equilateral triangle and octagonal.
For the stainless steel square pipe bearing fluid pressure, hydraulic test shall be carried out to check its pressure resistance and quality. It is qualified if there is no leakage, wetting or expansion under the specified pressure. Some steel pipes shall also be subject to crimping test, flaring test, flattening test, etc. according to the standard or the requirements of the demander.
Specification of square tube: 5 * 5 ~ 150 * 150 mm thickness: 0.4 ~ 6.0 mm.
Square tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347h, 310S.
Production technology of stainless steel square tube
- Round steel preparation → heating → hot rolling perforation → head cutting → pickling → grinding → lubrication → cold rolling → degreasing → solution heat treatment → straightening → pipe cutting → pickling → finished product inspection.
Application of stainless steel square tube
Stainless steel square tubes are widely used in construction, machinery manufacturing, steel construction and other projects, in shipbuilding, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, boiler construction, highway railing, house construction, pressure vessel, oil storage tank, bridge, power plant equipment, Hoisting and transportation machinery and other welded structural parts with high load are also widely used.
