Stainless Steel Pipe
Stainless steel pipe is a hollow, long, round steel bar used as a fluid conveying pipeline. It is widely used in industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation, as well as in mechanical structural components. Stainless steel pipe is made from acid- and heat-resistant steel billets through a process of heating, perforation, sizing, hot rolling, and cutting.
Product Introduction
Classification
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 bimetallic composite pipes, plated and coated pipes for saving precious metals and meeting special requirements. . There are many kinds of stainless steel pipes, different uses, different technical requirements and different production methods. The outer diameter of the currently produced steel pipe ranges from 0.1 to 4500mm, and the wall thickness ranges from 0.01 to 250mm. In order to distinguish its characteristics, steel pipes are usually classified as follows.

Ways to produce
Stainless steel pipes are divided into two categories: seamless pipes and welded pipes according to production methods. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled pipes are the secondary Processing; welded pipes are divided into straight seam welded pipes and spiral welded pipes, etc.
Category of use
According to the application, it can be divided into oil well pipe (casing, oil pipe and drill pipe, etc.), line pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking pipe) ) and marine pipes, etc.
Production
Stainless steel welded pipe production process:
Raw material--slitting--welding pipe--repairing--polishing--inspection (printing)--packaging--shipping (warehousing) (decorative welded pipe).
Raw material--slitting--welding pipe--heat treatment--correction--straightening--end trimming--pickling--water pressure test--inspection (printing)-packaging--shipping (warehousing) (Welded pipes for industrial piping).
