Stainless Steel Tube
This is stainless steel seamless tube for boiler. The manufacturing method is the same as seamless pipe, but there are strict requirements for the steel grades used in manufacturing steel pipe. High pressure boiler tubes are often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the tubes will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.
Application: Stainless steel seamless boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas pipes and main steam pipes of high pressure and ultra-high pressure boilers.
