The main features of ordinary cold drawn seamless steel tubes are welded joints, which can withstand great pressure. The product can be a very rough cast or cold dial. Precision cold rolling seamless steel tube is a product appearing in recent years. It has strict tolerances and roughness on the inner and outer walls. Cold drawn or cold rolled precision seamless steel tubes are cold drawn or cold rolled precision seamless steel tubes for mechanical structure and hydraulic equipment with high dimensional accuracy and good surface finish. The use of precision seamless steel pipe to make mechanical structure or hydraulic equipment can greatly save the time of machining, improve the utilization of materials, and improve the quality of the products. Precision steel pipe is a kind of high precision steel pipe material after cold drawing or cold rolling. Because the inner and outer wall of the precision steel pipe has no oxidation layer, high pressure and no leakage, high precision, high smoothness, cold bending and no deformation, expansion, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless tubes or welded joints (through cold rolling). Cold rolled precision steel tubes are widely used in automobiles, motorcycles, electric vehicles, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, medium and low pressure boilers and other fields. The characteristics of precision cold drawn seamless steel pipe are as follows: 1) the outside diameter is smaller. 2) high accuracy, small batch production 3) cold drawn (rolled) seamless steel pipe has high accuracy and good surface quality. 4) the cold drawn seamless steel pipe cross area is more complex. 5) the performance of cold drawn seamless steel pipe is better than that of seamless steel pipe. 6) the condition of the cold drawn seamless steel pipe is reduced, and the inside and outside diameter can be controlled in the 10 wire, which is used for the mechanical structure, the high precision of the hydraulic equipment and the good surface finish, and the cold rolling precision seamless steel pipe. The use of precision seamless steel pipe to make mechanical structure or hydraulic equipment can greatly save the time of machining, improve the utilization of materials, and improve the quality of the products. Seamless steel pipe has a very important position in the steel pipe industry of our country. Because of its different manufacturing technology, it is divided into two kinds of hot rolled (extrusion) seamless steel tube and cold drawn (rolling) seamless steel tube, and the cold drawing tube is divided into circular tube and special tube. Seamless steel tubes are also divided into the following varieties for their different uses:

1.The structure is made of seamless steel pipe. It is mainly used in general structure and mechanical structure.

2.Seamless steel pipe for fluid transport. It is mainly used for conveying fluid pipes on engineering and large equipment.

3.Seamless steel pipe for low medium pressure boiler. It is mainly used for transporting low medium pressure fluid in industrial boilers and domestic boilers.

4.Seamless steel pipe for high pressure boiler. It is mainly used for high temperature and high pressure conveying fluid collecting box and pipeline in power plant and nuclear power plant boiler.

5.The ship uses carbon steel and carbon manganese steel for seamless steel pipe. It is mainly used for marine boiler and Superheater I and II class pressure pipe.6.A seamless steel pipe for high pressure chemical fertilizer equipment. It is mainly used for transporting high temperature and high pressure fluid pipes on chemical fertilizer equipment.

7.Seamless steel pipe for petroleum cracking. It is mainly used for boilers, heat exchangers and delivery fluid pipes in petroleum refineries.

8.Seamless steel pipe for cylinder. It is mainly used to make all kinds of gas and hydraulic cylinders.
