Low carbon steel pipe-carbon content is about less than 0.25%. Carbon steel pipes in oil products, oil and gas and public media with a design pressure lower than 10MPa-carbon content is between 0.25 and 0.60%, such as 35, 45 steel, etc.; high carbon steel pipes-carbon content is greater than Around 0.60%. This type of steel is generally not used in the manufacture of steel pipes. Carbon steel pipe-introduction Carbon steel pipe contains a certain amount of carbon, as well as silicon and manganese. Does not contain other alloying elements. Note that the silicon content generally does not exceed 0.40%. In order to ensure the chemical composition and mechanical properties of carbon steel pipes, we must control the content of impurities such as sulfur and phosphorus below 0.035%. Only in this way can high-quality carbon steel pipes be produced.
