    Information

      Features of cold drawn precision hydraulic black phosphating seamless steel pipe:

      1. Cold drawn precision hydraulic black phosphating seamless steel pipe has high tolerance and dimensional accuracy, and the product accuracy is controlled within ±5mm. The inner and outer walls are smooth and the surface has no oxide layer.

      2. The comprehensive performance of cold drawn precision hydraulic black phosphating seamless steel pipe is excellent, can withstand high pressure, cold bending, flaring, flattening without cracking, no wrinkle, and capable of various complex deformations and mechanical processing.

      3. The popularization and application of precision seamless pipes can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save mechanical processing man-hours, increase production volume and material utilization, and at the same time help improve product quality and reduce cost.

      Purpose of precision drawn bright precision seamless steel pipe:

      Cold drawn precision hydraulic black phosphating seamless steel pipe is a high-precision steel pipe processed by cold drawing or hot rolling. Since the inner and outer walls of precision seamless steel pipes have no oxide layers, they are mainly used for the production of pneumatic or hydraulic components due to the advantages of precision seamless steel pipes, which can withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening and no cracks. All of the products, such as cylinders or oil cylinders, use seamless tubes. The chemical composition of precision seamless steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.

      The difference between cold drawn precision hydraulic black phosphating seamless steel pipe

      4. The main feature of cold drawn precision hydraulic black phosphating seamless steel pipe is that it has no welded seam and can withstand greater pressure. The product can be rough cast or cold drawn parts.

      5. Cold drawn precision hydraulic black phosphating seamless steel pipe is a product that has appeared in recent years, mainly because the inner hole and outer wall dimensions have strict tolerances and roughness.

      6. Features of cold drawn precision hydraulic black phosphating seamless steel pipe

      1). The outer diameter is smaller. 2). High precision can be produced in small batches. 3). The cold drawn (rolled) finished product has high precision and good surface quality. 4). The horizontal area of ​​the steel pipe is more complicated. 5). The performance of the steel pipe is superior, and the metal is denser.
