Best quality cold rolled tube manufacturer, cold rolled pipe
Hydraulic cylinder tube is a kind of after cold rolling processing of a kind of high precision steel tube, full name cold rolled precision seamless steel tube. Precision seamless steel tube wall inside and outside the precision seamless steel pipe seamless steel pipe without oxidation layers, under high pressure without lea, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc. It is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, are made seamless tube. The chemical composition of precision seamless steel tube with carbon sulfur C, Si, Mn, S, P, Cr.
The difference between precision steel pipe and seamless pipe:
1. The seamless steel tube with obvious difference is that dimensional accuracy can be up to 0.1mm.
2. High precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.
