High-pressure boiler pipesBoiler TubeA type belonging to the seamless steel tube category. The manufacturing method is the same as that of seamless tubes, but there are strict requirements for the steel grades used in the manufacturing of steel tubes. High-pressure boiler tubes are often used under high temperature and high-pressure conditions. Under the action of high-temperature flue gas and steam, the tubes may undergo oxidation and corrosion. It is required that the steel tubes have high tensile strength, excellent anti-oxidation and corrosion resistance, and good structural stability. High-pressure boiler tubes are mainly used for manufacturing high-pressure andUltra-high-pressure boilerOverheated tubes, reheater tubes, conduit tubes, main steam pipes, etc.
