Introduction And Classification of Stainless Steel Tubes

Stainless steel round tube is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial conveying pipelines and mechanical structural components. 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. Stainless steel round tube is also commonly used to produce a variety of conventional weapons, barrels, shells and so on.

Classification

Such steel tubes can be divided into two categories: stainless steel seamless steel tubes and stainless steel welded steel tubes (with seam tubes).According to the manufacturing process, there are several basic types of hot rolling, extrusion, cold drawing and cold rolling. According to the shape of the section, it can be divided into a circular tube and a special-shaped tube. A circular steel pipe is widely used, but there are also some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal and other shaped stainless steel pipe.

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

Seamless stainless steel round tube, also called stainless steel seamless tube, is made of steel ingot or solid tube 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 by the wall thickness in millimeters.

The 304 stainless steel round tube is called SUS304 stainless steel tube, and the SUS304 stainless steel round tube is a stainless steel tube of American grade material. The domestic grade is equivalent to 0Cr19Ni9 stainless steel tube, usually replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloying elements form a dense oxide film, which is insulated from oxygen and prevents further oxidation. Therefore, stainless steel is not "stainless".

Use of stainless steel tube

It is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. 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. It is also commonly used to produce a variety of conventional weapons, barrels, shells and so on.
