honed steel pipe

Quilted pipes are processed by rolling. Because the surface layer has residual compressive stress on the surface, it is helpful to close the surface micro cracks and prevent the expansion of erosion. Thus improving the surface corrosion resistance and delaying the generation or expansion of fatigue cracks, thereby improving the fatigue strength of honing pipes. By rolling forming, a cold work hardening layer is formed on the rolling surface, reducing the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the honing tube inner wall and avoiding burns caused by grinding. After rolling, the reduction of surface roughness value can improve the fitting properties.

Rolling processing principle:

It is a pressure finishing process that utilizes the cold plastic characteristics of metal at room temperature, and applies a certain amount of pressure to the surface of the workpiece using rolling tools, causing plastic flow of the surface metal of the workpiece and filling it into the original residual low concave valleys, thereby reducing the surface roughness of the workpiece. Due to the plastic deformation of the surface metal being rolled, the surface structure is cold hardened and the grains become finer, forming a dense fibrous structure and a residual stress layer. The hardness and strength are improved, thereby improving the wear resistance, corrosion resistance, and compatibility of the workpiece surface. Rolling is a non cutting plastic processing method.

Several advantages of honing pipes:

1. Improve the surface roughness, which can basically reach Ra ≤ 0.08 µ m.
2. Correct roundness, ovality can be ≤ 0.01mm.
3. Improve surface hardness, eliminate stress deformation, and increase hardness by HV ≥ 4 °
4. After processing, there is a residual stress layer, which increases the fatigue strength by 30%.
5. Improve the quality of the fit, reduce wear, and extend the service life of the parts, but the processing cost of the parts is actually reduced.
