Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetal composite pipes, plating and coating pipes to save precious metals and meet special requirements. . There are many types of stainless steel pipes, their uses are different, their technical requirements are different, and their production methods are also different. The currently produced steel pipes have an outer diameter range of 0.1-4500mm and a wall thickness range of 0.01-250mm.
Stainless steel pipes are divided into seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled are the secondary types of steel pipes. Processing; Welded pipes are divided into straight seam welded pipes and spiral welded pipes.
Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin-walled pipes and the successful development of new reliable, simple and convenient connection methods give it more irreplaceable advantages for other pipes, and more and more applications in engineering , The use will become more and more popular, and the prospects are promising.
According to the purpose, it can be divided into oil well pipes (casing, tubing and drill pipes, etc.), line pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high pressure fertilizer pipes, petroleum cracking pipes, etc.) ) And ship pipes.
Application requirements: automotive industry, folding petrochemical industry including fertilizer industry, folding water and gas and other fluid transportation, folding equipment manufacturing and maintenance.
