High pressure boiler tubes are in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and water vapor, the tubes will be oxidized and corroded. Steel pipes are required to have high durable strength, high anti-oxidation and corrosion resistance, and good structural stability. High pressure boiler tubes are mainly used to manufacture superheaters, reheaters, water wall and economizers of supercritical or supercritical boilers.
Our products, steel, excellent performance, not only can produce thick-walled pipes with a wall-to-diameter ratio of 36%, but also can produce thin-walled pipes with a wall-to-diameter ratio of less than 4%.
Our products use mature perforation technology, unique cold processing technology, advanced lubrication technology and stable and reliable heat treatment technology to overcome the ultra-supercritical environment of high temperature, high pressure and high steam corrosion. They have made important contributions to shorten the construction cycle of power plants and promote further cost reduction and efficiency improvement in the power industry. Contribution.
Our products are supplied by top boiler manufacturers at home and abroad, and their products have been successfully applied to power projects at home and abroad.
