By production method

It can be divided into seamless steel pipe and seamed steel pipe. Seamless steel pipes can be used in various industries such as liquid pressure pipelines and gas pipelines. Welded steel pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes, etc.

According to the use of steel pipe

1. Pipeline pipe. Such as: water, gas pipes, seamless pipes for steam pipes, petroleum pipelines, and pipes for oil and gas trunk lines. Agricultural irrigation faucets with pipes and sprinkler irrigation pipes, etc.

2. Tubes for thermal equipment. Such as boiling water pipes, superheated steam pipes for general boilers, superheated pipes for locomotive boilers, large smoke pipes, small smoke pipes, arch brick pipes, and high-temperature and high-pressure boiler pipes.

3. Pipes for machinery industry. Such as aviation structural tubes, automobile half-axle tubes, axle tubes, automotive tractor structural tubes, tractor oil cooler tubes, square tubes and rectangular tubes for agricultural machinery, transformer tubes, and bearing tubes.

4. Oil geological drilling pipe (octg pipe). Such as: oil drilling pipes, oil drill pipes, drill jacks, oil tubing, oil casing and various pipe joints, geological drilling pipes (core pipes, casings, active drill pipes, drill jacks, press hoops and pin joints, etc.).

5. Pipes for the chemical industry. Such as: petroleum cracking pipes, chemical equipment heat exchangers and pipes, stainless acid-resistant pipes, high-pressure pipes for fertilizers, and pipes for transporting chemical media.

6. Manage by other departments. Such as: tubes for containers (tubes for high-pressure gas cylinders and general container tubes), tubes for instruments, tubes for watch cases, tubes for injection needles and medical equipment, etc.

According to steel pipe material

Steel pipes can be divided into carbon pipes, alloy pipes, stainless steel pipes, etc. according to the pipe material (ie steel type). Carbon tubes can be divided into ordinary carbon steel tubes and high-quality carbon structural tubes. Alloy tubes can be divided into: low alloy tubes, alloy structural tubes, high alloy tubes, and high strength tubes. Bearing tubes, heat-resistant and acid-resistant stainless tubes, precision alloy (such as Kovar alloy) tubes and high-temperature alloy tubes, etc.
