Stainless steel pipe is a kind of hollow steel pipe that is not easy to rust. Stainless steel pipe is a hollow long cylindrical steel. Its scope of application is used as a pipeline for conveying fluids. It is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. Wait. Stainless steel pipes are made of acid-resistant and heat-resistant steel billets, which are heated, pierced, sizing, hot-rolled, and cut.
Classification of stainless steel pipes: stainless steel seamless steel pipes and stainless steel welded steel pipes. According to the outer diameter of the steel pipe, it can be divided into round pipes and special-shaped pipes. Round steel pipes are widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel pipes.
For steel pipes under fluid pressure, hydraulic tests and radiographic testing must be carried out to check their pressure resistance and quality. No leakage, wetting or expansion under the specified pressure is qualified. Some steel pipes must be carried out according to the standards or requirements of the buyer. Crimping test, flaring test, flattening test, etc.
Seamless stainless steel pipes, also called stainless steel seamless pipes, are made of steel ingots or solid pipe billets through perforation to make capillaries, and then hot rolled, cold rolled or cold drew. The specifications of seamless steel pipes are expressed in millimeters of outer diameter * wall thickness. The mechanism of stainless steel rust prevention is that alloy elements form a dense oxide film, which isolates oxygen from contacting and prevents continued oxidation. So stainless steel is not "stainless".
