Fluid seamless steel tube manufacturing method

- Apr 08, 2019-

Fluid seamless steel tube manufacturing method.Fluid seamless steel tube is a kind of hollow section, from beginning to end without weld.Steel pipe has hollow section, which is widely used as the pipe for transporting fluid, oil, natural gas, gas, water and some solid materials.Steel pipe and round steel and other solid steel compared, in the bending and torsion strength at the same time, the weight is lighter, is an economic section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drilling pipe, car shaft, bicycle frame and construction of steel scaffolding.


(1) general boiler tube temperature under 450 ℃, the domestic pipe mainly use 10, 20 carbon steel hot rolled or cold drawn tube manufacture.

(2) high pressure boiler tube is often used in high temperature and high pressure conditions, the pipe in the high temperature of smoke and water vapor, oxidation and corrosion will occur.Steel tubes are required to have high endurance strength, high oxidation resistance and good microstructure stability.


(2) use:

General boiler tube is mainly used to manufacture water wall tube, boiling water tube, superheated steam tube, locomotive boiler superheated steam tube, large, small smoke tube and arch brick tube.

     high pressure boiler tube is mainly used to manufacture high pressure and ultra-high pressure boiler superheater tube, reheater tube, pipe, main steam pipe and so on.
