20mn Fluid Pipe

Implementation Standards

Seamless steel tubes for fluid transport (GB/T8163-2008) are general seamless steels for water, oil, gas and other fluids

Applicable Scope

General boiler tubes are mainly used to make water wall tubes, boiling water pipes, superheated steam pipes, superheated steam pipes used for locomotive boilers, big and small smoke pipes and arch brick pipes, etc..

The high pressure boiler tube is mainly used to manufacture high-pressure and ultrahigh pressure boiler superheater, reheater pipe, main steam pipe etc..

However, the circular tube also has some limitations, such as under the condition of plane bending, the round tube is not as good as square and rectangular tube bending strength, some agricultural machinery skeleton, steel and wood furniture are commonly used square, rectangular tube. Special shaped steel tubes with different cross section shapes are needed for different purposes.
