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.

Cold drawn(rolled) precision steel pipe and the general difference between ordinary seamless steel pipe:
1, the general characteristics of ordinary seamless steel pipe is welded seam, can withstand greater pressure. The product can be very rough as cast or cold parts.
2, cold drawn precision steel pipe is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.
Cold drawn (rolled) precision steel pipe features:
1. smaller diameter.
2. High precision can be done small batch Health
3. Cold drawn (rolling) finished high precision, good surface quality.
4. Steel pipe cross-sectional area is more complex.
5. Steel pipe performance is superior, the metal is relatively dense.
