Difference of Carbon Steel Pipe and Seamless Steel Pipe

Along with the social development, demand of steel production increase gradually, more and more. Therefore, the development of modern city could not leave the carbon steel pipe. Carbon steel pipe USES a very wide range, such as electrified high-speed railway, transformer substation, the construction of communication facilities adopted in many aspects. So many steel materials, and carbon steel pipe belongs to which category? What is the difference between carbon steel pipes and seamless steel tube? How to divide up carbon steel pipe. Actually the carbon steel pipe mainly to determine the carbon content of them. According to how much a carbon carbon steel pipe for the following classification. Carbon steel pipe classification: low carbon steel pipe, carbon content is less than about 0.25%. Design pressure is lower than 10 mpa oil, oil and gas, and utility of medium carbon steel pipe, carbon content at about 0.25 ~ 0. 60%, such as 35 and 45 steel; High carbon steel pipe, carbon content is greater than 0.60%. This kind of steel is generally not used in the manufacture of steel pipe. Carbon steel pipe - introduces carbon steel tube containing a certain amount of carbon, silicon and manganese. Does not contain other alloying elements. Pay attention to the content of silicon is generally not more than 0.40%. In order to ensure that carbon steel chemical composition and mechanical properties, we must control the impurities such as sulfur and phosphorus content below 0.035%. In this way can we produce high quality carbon steel pipe.

Carbon steel pipe - use carbon steel pipe is rely on adjusting the carbon content to continuously strengthen the mechanical properties of carbon steel pipe, thus producing the different USES of carbon steel pipes, which are determined according to carbon content. Some zero can be used in the manufacture of mechanical structural steel pipe and building structure and transmission fluid pipe, etc. Also be used in agricultural irrigation and water conservancy engineering, wide range of USES.
