High-pressure steel pipe: mainly used to manufacture high pressure and above the pressure of the steam boiler pipe and other high-quality carbon structural steel, alloy structural steel
And stainless steel heat-resistant steel seamless steel pipe, the boiler tube by the party at high temperature and high pressure work, the tube in the role of high temperature flue gas and water vapor oxidation and corrosion, so the steel pipe has a high lasting strength, high Of the antioxidant properties, and has good tissue stability.
