Precision seamless pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of precise steel pipes have no oxide layer, withstand high pressure and no leakage, high precision, high gloss, cold bending deformation, flattening and no cracks, they are mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes, as well as welded pipes. The chemical composition of precision steel pipe is carbon C, silicon Si, manganese and manganese, sulfur S, phosphorus P, chromium and chromium.

　　Production Technology of Precision Seamless Tube

　　Precision seamless tubes are usually produced by cold rolling process. The specific process is as follows:

　　Round steel piercing pickling cold rolling saw head bundling

　　Seamless pipe pickling cold rolling saw head bundling

　　Characteristics and Advantages of Precision Seamless Tube

　　Characteristics of Precision Seamless Tube

　　1. It has high precision and saves the wastage of the working material of the machine processing users.

　　2. There are many specifications and wide applications.

　　3. Cold-rolled products have high precision, good surface quality and good straightness.

　　4. The inner diameter of steel pipe can be made into hexagonal shape.

　　5. Steel pipe has better performance and denser metal.
