High-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless steel tubing used for steam boiler tubing such as high pressure and above. These boiler tubes are often operated under high temperature and high pressure, and pipes are exposed to high temperature smoke. Oxidation and corrosion occur under the action of gas and water vapor. Therefore, the steel pipe is required to have high durability, high oxidation resistance, good structural stability, and hydraulic pillar tubing.
