Product Detail

Honed tube is a precision seamless tube with high dimensional accuracy and good surface finish after cold drawing and cold rolling, suitable for mechanical structures and hydraulic equipment. Using precision seamless steel pipes to manufacture mechanical structures or hydraulic equipment can greatly save processing time, improve material utilization, and improve product quality.

Honed tube is processed by scraping and rolling. Because the surface layer has residual compressive stress on the surface, it is helpful to close the surface micro cracks and hinder the expansion of Erosion. This improves the surface corrosion resistance and can delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the quilted tube. 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 inner wall of the grinding tube. After rolling, the reduction of surface roughness value can improve the fitting properties
