Classification and use of steel pipe

Keywords:classificatio, uses
According to production method
It can be divided into seamless steel pipe and welded steel pipe, and the welded steel pipe is referred to as straight seam steel pipe. Seamless steel pipes can be used in liquid pressure pipes and gas pipes in various industries. Welded pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes, etc.

According to the uses of steel pipe
1. Pipes for pipelines. Such as: water, gas pipe, steam pipe seamless pipe, oil pipeline, oil and gas trunk line pipe. Agricultural irrigation faucets with pipes and sprinkler pipes.

2. Tubes for thermal equipment. Such as general boiler boiling water pipes, superheated steam pipes, 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 (round tubes, elliptical tubes, flat elliptical tubes), automotive semi-axle tubes, axle tubes, automobile tractor structural tubes, oil cooler tubes for tractors, square and rectangular tubes for agricultural machinery, tubes for transformers, and bearings Tube and so on.

4. Pipes for oil geological drilling. Such as: oil drilling pipe, oil drill pipe (square drill pipe and hexagonal drill pipe), drill pipe, petroleum oil pipe, oil casing and various pipe joints, geological drilling pipe (core pipe, casing, active drill pipe, drilled , by hoop and pin joints, etc.).

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

6. Other departments use the tube. Such as: container tube (high pressure gas cylinder tube and general container tube), instrumentation tube, watch case tube, injection needle and its medical device tube.

According to the material of the steel pipe
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 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, high strength tubes. Bearing tubes, heat-resistant and acid-resistant stainless tubes, precision alloys (such as Kovar) tubes, and high-temperature alloy tubes.
