r3 r3 Seamless steel pipe for high-pressure boilers is a type of boiler pipe, which has strict requirements on the steel type and process used to manufacture the steel pipe. High-pressure boiler tubes are often exposed to high temperature and high pressure conditions during use. Under the action of high-temperature flue gas and water vapor, the tubes will oxidize and corrode. Steel pipes are required to have high lasting strength, high resistance to oxidation and corrosion, and good structural stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. for high-pressure and ultra-high-pressure boilers.
