Precision Steel tube is a pipe material through high-precision cold drawn or hot-rolled. Precision steel pipes inside and outside the wall oxide layer under high pressure without leakage, high-precision, high-quality finish, cold bending deformation, flaring, flattening without cracks, and so it is mainly used in the production of pneumatic or hydraulic components of the product, such as cylinder or cylinders, seamless pipe, welded pipe. Precision steel tubes chemical composition of the C, carbon, silicon of Si, manganese Mn, sulfur S, phosphorus P, Chromium Cr.
The difference between precision steel pipe and seamless steel pipe
1, the main features of the seamless steel pipe is welded seam, and can withstand greater pressure. Products can be very rough cast or cold call.
2, precision steel pipe products in recent years, mainly within the hole, the outer wall of tighter tolerances and roughness size.
