Short Description:

High pressure boiler tube is a type of boiler tube that belongs to the category of seamless steel pipes. The manufacturing method is the same as seamless pipes, but there are strict requirements for the steel grade used in the manufacturing of steel pipes. High pressure boiler tubes are often subjected to high temperature and pressure conditions when used. Under the action of high-temperature flue gas and water vapor, the tubes can undergo oxidation and corrosion. Steel pipes are required to have high endurance strength, high oxidation and corrosion resistance, and good organizational stability. High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam pipes, etc. for high and ultra-high pressure boilers.
