Product Description
The quilted steel pipe is a high-precision steel pipe treated by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision steel tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or cylinder. The chemical composition of quilted steel pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
The main advantages of quilted steel pipe:
1. Improve the surface roughness, the roughness can basically reach Ra≤0.08μm.
2. Correct the roundness, the ellipticity can be ≤0.05mm.
3. Improve surface hardness, eliminate stress and deformation, and increase hardness by HV≥4°
4. After processing, there is a residual stress layer, which improves the fatigue strength by 30%.
5. Improve the quality of fit, reduce wear, and prolong the service life of parts, but the processing cost of parts is reduced instead
Hydraulic steel pipes are basically divided into fluid pipes and oil steel bobbins used in hydraulic systems, also known as honing pipes, while cold-drawn or cold-rolled precision seamless steel pipes also include hydraulic steel pipes.
The fluid pipe on the hydraulic system is close to the domestic national standard GB3639-83. Introduction of hydraulic steel pipe: cold-drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish for hydraulic equipment. The precision seamless steel pipe is used to manufacture mechanical structures or hydraulic equipment, etc. The precision steel pipe is a high-precision seamless steel pipe after cold drawing or cold rolling. Because there are no oxide layers on the inner and outer walls of the precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce pneumatic or hydraulic products.
