 High-pressure boiler tubes is a boiler tube, seamless steel pipe category belongs. Seamless pipe manufacturing methods and the same, but the steel used in the manufacture of steel, there are strict requirements. 
 High-pressure boiler tubes often used in high temperature and high pressure conditions, high temperature gas and water vapor in the tube under the effect of oxidation and corrosion will occur. Requires durable steel with high strength, high resistance to oxidation corrosion, and have good organizational stability. Mainly used to manufacture high-pressure boiler tubes and high pressure high pressure boiler superheater tubes, reheater tube, airway, the main steam pipe.
