High-pressure alloy tube is a kind of tube that can be subjected to pressure, using this tube to transport liquids and gases. High-pressure alloy tube: mainly used to manufacture high-pressure and above pressure steam boiler pipeline with high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel tube, these boiler tubes by the party in the high temperature and high pressure work, the tube in the high temperature flue gas and the role of water vapor oxidation and corrosion will occur, so the requirements of the steel tube has a high enduring strength, high resistance to oxidation, and has a good organizational stability.
