High pressure boiler tube
High-pressure boiler tubes are mainly used to manufacture excellent carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipes for steam boiler pipes with high pressure and above. These boiler tubes are operated by the Party under high temperature and high pressure industrial dust, and the tubes are oxidized and corroded under the action of high temperature flue gas and water vapor. Therefore, the steel tubes are required to have high lasting strength, high oxidation resistance and good organizational stability.
