Through continuous improvement of service competitiveness, won the praise of the market. Song style; precision steel pipe is a high precision steel tube material after cold drawing or hot rolling. Precision steel pipes are mainly used for the production of pneumatic or hydraulic components, such as cylinders or cylinder products, they can be seamless or welded, but most of them are precision seamless steel. Precision pipe has the advantages of high outer surface of pipe after heat treatment, no flattening crack, cold bending deformation, high pressure resistance, and various complex deformation and mechanical processing. Deep processing. It mainly produces steel pipe grades 10, 20, 35 and so on. Precision steel pipe;

The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
