High pressure boiler tube is a kind of boiler tube, belongs to seamless steel pipe category. The manufacturing method is the same as seamless pipe, but there are strict requirements on the steel used to make the steel pipe. High pressure boiler tube is often used in high temperature and high pressure conditions, the tube under the action of high temperature flue gas and water vapor, oxidation and corrosion will occur. The steel pipe is required to have high lasting strength, high resistance to oxidative corrosion, and good organizational stability. High pressure boiler tube is mainly used to manufacture high pressure and super high pressure boiler superheater tube, reheater tube, guide pipe, main steam pipe, etc.
