Carbon steel pipes are made of steel ingots or solid round steel by perforating capillaries, and then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipes are divided into two types: hot-rolled and cold-rolled (drawn) steel pipes.
Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel thebirdsworld.
Cold-rolled (dial) carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes.
It also includes carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless steel thin-walled steel pipes, and special-shaped steel pipes.
The use and classification of carbon steel pipe
- Pipes for thermal equipment. Such as boiling water pipes and 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 infosportsworld.
- 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 pipes, etc.
- 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, etc.
- Pipes for petroleum geological drilling. Such as: oil drilling pipe, oil drill pipe (kelly and hexagonal drill pipe), drill jack, oil tubing, casing pipe and various pipe joints, geological drilling pipe (core pipe, casing, active drill pipe, drill jack, Press hoops and pin joints, etc.).
- Pipes for machinery industry. Such as aviation structural tubes, automotive 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.
- Managed 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.
