High-pressure boiler tubesBoiler TubeA type belongs to the category of Seamless Steel Pipes. The manufacturing process is the same as that of seamless pipes, but there are strict requirements for the steel grades used in the production of steel pipes. High-pressure boiler pipes are often used under high temperature and high-pressure conditions, where the pipes undergo oxidation and corrosion under the action of high-temperature flue gas and steam. It is required that the steel pipes have high tensile strength, excellent oxidation and corrosion resistance, and good structural stability. High-pressure boiler pipes are mainly used for manufacturing high-pressure andUltra-high-pressure boilerOverheated tubes, reheater tubes, guide tubes, main steam pipes, etc.
