High-pressure boiler tubes are mainly used to manufacture superheaters, reheaters, water-cooled walls, economizers, etc. of supercritical or ultra-supercritical boilers. The steel tubes are required to have high endurance strength, high oxidation and corrosion resistance, and good structural stability.

Product features
High-pressure boiler pipes are often used under high temperature and high pressure conditions. Under the action of high-temperature flue gas and water vapor, the pipes will oxidize and corrode. Therefore, high-pressure boiler steel pipes have high lasting strength, high anti-oxidation and corrosion performance, and good organizational stability.
