The difference and application of cold-drawn precision hydraulic black phosphated seamless steel tubes and precision drawn and b
Cold-drawn precision hydraulic black phosphate seamless steel pipe features:
1. Cold-drawn precision hydraulic black phosphate seamless steel pipe has high dimensional accuracy tolerance, product precision is controlled within ±5mm, internal and external wall finish is good, and there is no oxide layer on the surface.
2. Cold-drawn precision hydraulic black phosphate seamless steel pipe has excellent comprehensive performance, can withstand high pressure, cold bending, flaring, flattening without cracking, wrinkle-free, can do all kinds of complex deformation and mechanical processing.
3. The promotion and application of precision seamless pipe can save steel, improve processing efficiency, reduce processing and equipment investment, save costs and greatly reduce machining man-hours, increase production and material utilization, and help improve product quality and reduce cost.
Precision drawing bright precision seamless steel pipe use:
Cold-drawn precision hydraulic black phosphating seamless steel pipe is a kind of high-precision steel pipe after cold-drawing or hot-rolling. Because the precision seamless steel pipe inner and outer wall without oxide layer precision seamless steel pipe, withstand high pressure and no leakage, high precision, high finish, cold bending deformation, flaring, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components Products such as cylinders or cylinders are made of seamless tubes. The chemical composition of precision seamless steel tubes is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
Cold-drawn precision hydraulic black phosphate seamless steel pipe difference
4. The main feature of cold-drawn precision hydraulic black phosphating seamless steel pipe is that it has no welding seam and can withstand greater pressure. The product can be very rough cast or cold dial. The
5, cold-drawn precision hydraulic black phosphating seamless steel pipe is a product that has emerged in recent years, mainly the inner hole, the outer wall size has strict tolerances and roughness.
6, the characteristics of cold-drawn precision hydraulic black phosphate seamless steel pipe
1). The outer diameter is smaller. 2). High precision can be done in small batches 3). Cold drawn (rolled) finished products have high precision and good surface quality. 4). The transverse area of the steel tube is more complicated. 5). The steel pipe performance is superior, and the metal is comparatively dense.
