Precision steel tubing is a kind of high precision steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of precise steel pipe have no oxide layer, withstand high pressure and no leakage, high precision, high gloss, cold bending without deformation, flattening without cracks and so on, it is mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes. Seamless steel pipe is made of whole metal and has no seams on the surface. It is called seamless steel pipe. According to the production method, the seamless pipe is divided into a hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. According to the cross-section shape, seamless steel pipe can be divided into two types: circular and irregular. The irregular pipe has many complex shapes, such as square, ellipse, triangle, hexagonal, melon seed, star, and finned pipe. The diameter is 650 mm and the minimum diameter is 0.3 mm. According to different uses, there are thick-walled and thin-walled tubes. Seamless steel tubing are mainly used for petroleum geological drilling pipes, cracking pipes for the petrochemical industry, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors, and aviation.
