Basic knowledge of stainless steel pipe

First, the type of stainless steel pipe
According to its shape and use, stainless steel pipes are usually divided into two types: seamless stainless steel pipes and welded stainless steel pipes. Seamless stainless steel pipe is the use of uniform wall thickness, good formability of stainless steel billet production, mainly used for the production of high-quality cylinder, tubing, pressure pipe and other high demand products; Welded stainless steel pipe is made of coil tube and then connected by welding process, which is mainly used for manufacturing industrial water pipes and decorative pipes with general requirements.

Second, stainless steel pipe manufacturing process
Stainless steel pipe manufacturing process mainly includes cold drawing, hot rolling, hot extrusion, extrusion and welding and other methods, of which hot rolling and welding are the most widely used two methods. The stainless steel pipe produced by hot rolling has smooth surface, high density and good mechanical properties. Stainless steel pipes produced by welding are cheaper and more widely used.

Third, the chemical composition of stainless steel pipe
Stainless steel pipes are mainly composed of iron, chromium, nickel and a small amount of silicon, manganese, molybdenum and other elements. Among them, chromium element plays the main component of stainless steel, and nickel element increases the toughness and strength of stainless steel.

Four, stainless steel pipe surface treatment
The surface treatment of stainless steel pipes is usually carried out by polishing, sandblasting, electroplating, spraying, etc. Among them, polishing is the most basic surface treatment method, which can produce high brightness and smooth surface effect; Sand blasting can increase the tensile strength and corrosion resistance of stainless steel pipe. Electroplating and spraying can add a protective layer on the surface of the pipe to enhance the corrosion resistance and wear resistance of the stainless steel pipe.

Five, the characteristics and advantages of stainless steel pipes
Compared with traditional steel pipes, stainless steel pipes have a variety of unique characteristics and advantages, including the following:

1. Good corrosion resistance: The special chemical composition of stainless steel pipes can increase its corrosion resistance and excellent corrosion resistance.

2. Low density and high strength: Because the density of stainless steel pipe is small, its weight is light, but it can ensure its good toughness and strength.

3. Has good mechanical properties: the tensile strength and compressive strength of stainless steel pipe are better than ordinary steel pipe, with good mechanical properties and wear resistance.

4. Long service life: the plastic, toughness and corrosion resistance of stainless steel pipes are superior, and the service life often exceeds that of traditional steel pipes.

In summary, stainless steel pipes have a wide range of applications in many fields, such as construction, home, machinery industry and other fields. Under the same action, the use of stainless steel pipes can more effectively improve the service life, strength and other product performance of the product, so the selection of stainless steel pipes in the corresponding scene has certain advantages.
