Cold drawn black phosphated hydraulic seamless steel pipe

Features of cold drawn black phosphated hydraulic seamless steel pipes:

1. Cold drawn black phosphated hydraulic seamless steel pipes have high dimensional accuracy in public service, product accuracy is controlled within ± 5mm, internal and external wall smoothness is good, and there is no oxide layer on the surface.

2. The induction function of cold drawn black phosphated hydraulic seamless steel pipes is excellent, capable of accepting high pressure, cold bending, expanding, flattening without cracking, wrinkling, and being able to perform various miscellaneous deformation and mechanical processing treatments.

3. The promotion and application of cold drawn black phosphating hydraulic seamless pipes can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save mechanical processing hours, improve production volume and data utilization, and together, help to improve product quality and reduce costs.

Cold drawn black phosphated hydraulic seamless steel pipes are used for:

Cold drawn fine hydraulic black phosphating seamless steel pipe is a high-precision steel pipe that is processed by cold drawing or hot rolling. Due to the advantages of seamless steel pipes with no oxidation layer on the inner and outer walls, no leakage under high pressure, high precision, high smoothness, no deformation during cold bending, flaring, flattening, and no cracks, seamless pipes are primarily used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders. The chemical composition of fine seamless steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.

Differences in cold drawn black phosphated hydraulic seamless steel pipes

1. The primary feature of cold drawn fine hydraulic black phosphating seamless steel pipes is that they have no welded joints and can withstand large pressures. The product can be a very rough cast or cold drawn part.

2. Cold drawn fine hydraulic black phosphating seamless steel pipe is a product that has emerged in recent years, mainly due to strict public service and roughness of the inner hole and outer wall dimensions.

3. Characteristics of Cold Drawn Fine Hydraulic Black Phosphating Seamless Steel Pipe

1) Smaller outer diameter. 2) High precision can be used for small batch production. 3) Cold drawn (rolled) finished products have high precision and good surface quality. 4) The cross-sectional area of the steel pipe is more disorderly. 5) Steel pipes have superior functions and the metal is denser.
