Processing technology of gas cylinder tube

- Sep 15, 2020-

The cylinder tube is processed by rolling. Due to the residual compressive stress remaining on the surface layer, it helps to close the micro-cracks on the surface and hinder the expansion of erosion. Thereby improving the surface corrosion resistance, and can delay the occurrence or expansion of fatigue cracks, thus improving the fatigue strength of the cylinder tube. Through rolling forming, a cold-work hardened layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the cylinder tube and avoiding burns caused by grinding. After rolling, the surface roughness value decreases, which can improve the matching properties.
