With the development of society, the steel production is increasing, and the demand is increasing. Therefore, the development of modern cities can not leave the carbon steel pipe. Carbon steel pipe is widely used, such as the construction of high-speed railway, substation, communication facilities, etc.. So many steel materials, and carbon steel which belong to a category? Carbon seamless steel pipe and seamless steel pipe and what is the difference? How to divide the carbon steel pipe. In fact, carbon steel pipe is mainly determined by the carbon content. According to the carbon content of the number of carbon steel pipe for the following classification. Carbon steel pipe classification of the whole network hot metal parts! Sales witness! Click to understand "low carbon steel pipe - carbon content is about less than 0.25%. The design pressure is lower than 10MPa of the oil, oil and gas and the common medium carbon steel pipe - carbon content is about 0.25 ~ 0. Between 60%, such as 35, 45 steel, etc.; high carbon steel pipe - carbon content is greater than 0.60% or so. Such steels are not generally used in the manufacture of steel tubes. Carbon steel pipe - introduction of carbon steel pipe contains a certain amount of carbon elements, as there are silicon and manganese. Does not contain other alloy elements. Note that silicon content is generally not more than 0.40%. In order to ensure the chemical composition and mechanical properties of carbon steel pipe, we must control the content of impurities such as sulfur and phosphorus in the following 0.035%. So as to produce high quality carbon steel pipe.

Carbon steel pipe carbon steel pipe is to rely on the adjustment of carbon content to continue to strengthen the mechanical properties of carbon steel pipe, resulting in the production of carbon steel tubes of different purposes, which are determined according to the amount of carbon. Some can be used for the manufacture of mechanical structure and the construction of parts and transmission fluid pipelines and so on. Is also used in agricultural irrigation and water conservancy projects, the use of a wide range of.

The difference between the 1 seamless steel pipe and the carbon steel pipe is the seamless steel tube which is produced by the hot rolling method. Sometimes it is necessary to further cold working after heat treatment, which is in order to obtain the corresponding shape and size. And carbon steel tubes are generally made into round, square, flat, and so on. 2 seamless steel pipe is now the most used in the petrochemical production plant pipe. Carbon steel tubes are more widely used. While carbon steel pipe is the main requirement of its chemical composition is carbon content, seamless steel pipe is a large type, refers to seamless steel pipe, a wide range of.
