Steel pipe network to provide: stainless steel pipe knowledge

Stainless steel pipe is a kind of hollow long round steel, mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transmission pipelines and mechanical structural components. In addition, when the bending and the torsional strength are the same, the weight is lighter, so it is also widely used for manufacturing mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.
This type of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (seamed pipe) in two categories, according to the different manufacturing processes can be: hot-rolled, extruded, cold-drawn and cold-rolled several basic types, according to section The shape can be divided into round tubes and shaped tubes. Circular steel tubes are widely used, but there are also some special-shaped stainless steel tubes such as square, rectangular, semi-circular, hexagonal, equilateral triangle, and octagon.
For steel pipes subject to fluid pressure, hydraulic tests are required to test their pressure resistance and quality. No leaks, soaking, or swelling are acceptable under the specified pressure. Some steel pipes are also subjected to crimping tests according to standards or demand-side requirements. Flaring test, flattening test.
Seamless stainless steel tubes, also called stainless steel seamless tubes, are made by punching a steel ingot or solid tube and then hot-rolled, cold-rolled, or cold drawn. The specifications of the seamless steel pipe are expressed in terms of outer diameter*thickness mm.
304 stainless steel tube full name SUS304 stainless steel tube SUS304 stainless steel tube belongs to the US grade material stainless steel tube, domestic brand equivalent to 0Cr19Ni9 stainless steel tube, usually with 0Cr18Ni9 instead.
The mechanism of stainless steel rust prevention is that the alloy elements form a dense oxide film, which blocks oxygen contact and prevents further oxidation. So stainless steel is not "stainless."
