High pressure boiler tube
High pressure boiler tube is a kind of boiler tube, which belongs to the category of seamless steel tube. The manufacturing method is the same as that of the seamless pipe, but there are strict requirements for the steel used in the manufacture of the steel pipe. High-pressure boiler tubes are often used under high temperature and high pressure conditions, and the tubes will be oxidized and corroded under the action of high temperature flue gas and water vapor. The steel pipe is required to have high lasting strength, high oxidation and corrosion resistance, and good organizational stability. High pressure boiler tube is mainly used to manufacture high pressure and ultra high pressure boiler superheater tube, reheater tube, gas pipe, main steam pipe, etc.
