Classification of steel pipes by use
1. Pipes for pipes. For example, seamless pipes for water, gas, and steam pipelines, oil transmission pipes, and pipes for oil and natural gas trunk lines. Agricultural irrigation faucets with pipes and sprinkler irrigation pipes.
2. Pipes for thermal equipment. Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes, large smoke pipes, small smoke pipes, arch brick pipes, and high-temperature and high-pressure boiler pipes for locomotive boilers.
3. Pipe for mechanical industry. Such as aviation structural tubes (round, elliptical, flat elliptical tubes), automotive half axle tubes, axle tubes, automotive tractor structural tubes, tractor oil cooler tubes, agricultural machinery square and rectangular tubes, transformer tubes, and bearing tubes.
4. Pipes for petroleum geological drilling. Such as: petroleum drilling pipe, petroleum drill pipe (kelly and hexagonal drill pipe), drill stem, petroleum tubing, petroleum casing and various pipe joints, geological drilling pipe (core pipe, casing, active drill pipe, drill stem, press collar and pin joint, etc.).
5. Pipes for the chemical industry. Such as: petroleum cracking pipes, chemical equipment heat exchanger and pipeline pipes, stainless acid resistant pipes, high pressure pipes for fertilizer, and pipes for transporting chemical media.
6. Pipes for other departments. For example, pipes for containers (high-pressure gas cylinders and general containers), instruments and instruments, etc.
