High-pressure boiler tubes are a kind of boiler tubes and belong to the category of seamless steel tubes. The manufacturing method is the same as that of the seamless pipe, but there are strict requirements for the steel used for manufacturing the steel pipe. The high-pressure boiler pipe is often used under high temperature and high pressure conditions. The pipe is oxidized and corroded under the action of high-temperature flue gas and water vapor. Requires high durability of the steel pipe, high resistance to oxidation corrosion, and good organization stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air tubes, and main Steam pipe and so on.
