GB 3087 Grade 20 Seamless Boiler Tubes

No. 20 steel seamless steel pipe GB/T3087 is a common steel pipe material with high strength and good corrosion resistance. It is widely used in petroleum, chemical industry, electric power, construction and other fields.
The outer diameter of the 20-gauge seamless steel pipe is 273 mm and the wall thickness is 9 mm. At the same time, other geometric dimensions and physical properties of this steel pipe material are also specified, such as length, curvature, pressure resistance, etc. These regulations are very important to ensure the quality and reliability of steel pipes.
The production process of No. 20 steel seamless boiler steel pipes mainly includes smelting, rolling, heat treatment and other links. First, add molten iron to the electric furnace and add appropriate amounts of carbon, silicon, manganese and other elements for smelting. Then, the refined molten steel is injected into the rolling mill for rolling to form a tube blank. Finally, heat treatment is performed to improve the strength and corrosion resistance of the steel pipe.
