the application of alloy steel pipe

The application of alloy steel pipe mainly applies in power plant, nuclear power station, high pressure boiler, high temperature superheater and reheater of high temperature and high pressure pipeline and devices. Alloy steel pipe adopts high quality carbon steel, alloy structural steel and heat resistance stainless steel as raw material through hot rolling or cold drawn.


    
Alloy steel seamless pipe is named according to the raw material, while the seamless steel pipe is named according to the production process. The alloy steel pipe with the seam is different from the seamless steel pipe. The materials of alloy steel pipe includes: 16-50Mn、27SiMn、40Cr、12-42CrMo 16Mn 12Cr1MoV T91 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 45CrMo etc. Above all, the alloy steel can 100% recycle conformed with environmental protection, energy saving and resource conservation of national strategy. And government encourages the expansion application of high pressure alloy steel pipe.

Alloy steel pipe with hollow section is broadly utilized to transfer fluid such as oil, natural gas, coal gas, water and pipeline of solid material. Compared with solid round steel, the weight is lighter at the same bending torsional strength. Alloy steel pipe is a kind of economic cross section steel and widely used to produce structural and mechanical parts like petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding. With alloy steel pipe to make annular parts like rolling bearing and jack sets etc. can improve material utilization and simplify manufacturing process. At present it has been broadly to make steel pipe. Depending on different cross section, alloy steel pipe is divided into round steel pipe and deformed steel pipe. In addition, the circle cross section is under radial pressure whatever is the internal or external, the pressure is relatively uniform. So a majority of steel tube is round structure.
