　　Seamless steel oil pipeline is a kind of low-carbon steel pipe. Carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel. In general, if there is no special requirement for clad steel seamless steel oil pipeline, No.20 seamless steel oil pipeline is generally used. The material of 20 steel seamless steel oil pipeline is 20 steel, which is not quenched and has no brittleness of tempering. The cold deformation is of high plasticity, which is generally used for bending, rolling, bending and hammer arch, etc. the welding performance of arc welding and contact welding is very good, and the thickness of gas welding is small. Generally, it is used to manufacture the bars with low pressure resistance but high toughness demand.

　　The outer diameter and wall thickness of seamless steel oil pipeline can have a little deviation, but it should conform to relevant regulations. As one of the most important components of steel products, the seamless steel oil pipeline of steel is divided into two categories:10 Inch Seamless Steel Oil Pipeline and welded steel pipe because of its different manufacturing process and the shape of the used tube blank. Because of the different manufacturing process, the seamless oil pipeline of Steel is divided into hot rolling type and cold drawing type. Cold drawing type is divided into round tube and special pipe.

　　No.20 seamless steel oil pipeline is made of steel ingot or solid billet through perforation, and then through hot rolling, cold rolling or cold drawing. No.20 steel clad seamless steel oil pipeline plays an important role in China's steel pipe industry. The production process of steel seamless steel oil pipeline is rigorous, and it is not allowed to make a millisecond difference outside the specified range, which is one of its advantages. In the use process, there is no need to worry about the loss caused by poor quality.
