What are the materials and uses of seamless carbon steel pipe?

Seamless carbon steel pipes are capillaries made of steel castings or solid round steel through holes, and then made by hot rolling, cold rolling or cold drawing. Carbon steel pipe occupies an important position in my country's seamless steel pipe industry. The key materials are mainly q235, 20#, 35#, 45#, 16 million. The most important product implementation standards include national standards, American standards, Japanese standards, etc., among which national standards include the Ministry of Chemical Industry standards, Sinopec pipe fitting standards, power engineering pipe fitting standards, etc. Let's take a look at the benefits of carbon steel pipes.

Application of carbon steel pipe:

1. Tube for tube. Such as: seamless pipe for water, gas pipes, steam pipes, oil pipes, pipes for oil and natural gas trunk lines. Agricultural irrigation faucets and sprinkler pipes with pipes, etc.
2. Tubes for thermal equipment. Such as ordinary boiler boiling water pipe, superheated steam pipe, superheated pipe, large smoke pipe, small smoke pipe, arch brick pipe and high temperature and high pressure boiler pipe of locomotive boiler.
3. Pipes for machinery industry. Such as aviation structure tubes (round tubes, elliptical tubes, flat elliptical tubes), automobile semi-axle tubes, axle tubes, automobile tractor structure tubes, tractor oil cooler tubes, agricultural machinery square tubes and rectangular tubes, transformer tubes and bearing tubes, etc.
4. Petroleum geological drilling pipe. Such as: oil drill pipe, oil drill pipe (kelly and hexagonal drill pipe), drill pipe, oil tubing, oil casing and various pipe joints, geological drill pipe (core pipe, casing, active drill pipe, drill pipe ), clamps and pin joints, etc.).
5. Chemical pipelines. Such as: petroleum cracking pipes, chemical equipment heat exchangers and pipes, stainless steel acid-resistant pipes, high-pressure pipes for chemical fertilizers, chemical medium conveying pipes, etc.
6. Other departments use pipes. Such as: tubes for containers (tubes for high-pressure gas cylinders, tubes for general containers), tubes for instruments, tubes for watchcases, injection needles, tubes for medical devices, etc.

According to the 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 pipes can be further divided into ordinary carbon steel pipes and high-quality carbon structural pipes. Alloy tubes can be further divided into: low alloy tubes, alloy structural tubes, high alloy tubes, and high strength tubes. Bearing tube, heat and acid resistant stainless steel tube, precision alloy (such as Kovar alloy) tube, high temperature alloy tube, etc.
