honed cylinder tube
honed cylinder tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because the inner and outer walls of the quilted cylinder tube have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other points, it is mainly used for the production of pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless pipe.
Honed cylinder tube description
honed cylinder tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because the inner and outer walls of the quilted cylinder tube have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other points, it is mainly used for the production of pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless pipe. The chemical composition of the quilted cylinder tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
The quilted cylinder tube is processed by rolling. Because the surface layer has surface residual compressive stress, it is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed, so as to improve the fatigue strength of the quilted cylinder pipe. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the inner wall of the quilted cylinder tube and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness can improve the fit property.
Difference between honed cylinder and seamless steel tube
1、seamless steel pipe is mainly characterized by no welding joints, can withstand greater pressure. The product can be very rough cast or cold - drawn.
2、Quilted cylinder tube is a product that has appeared in recent years. It mainly has strict tolerance and roughness for inner hole and outer wall size.
