Drawn tube cylinder Properties

- Mar 10, 2021-

The oil cylinder tube is processed by rolling. Because the surface layer has residual surface stress, it helps to close the micro cracks on the surface and hinder the expansion of corrosion. Thereby improving the surface corrosion resistance, and can delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the quilted pipe. Through roll forming, a cold work hardened layer is formed on the rolled surface, which reduces the elastic and plastic deformation of the surface of the grinding pair contact degree, thereby improving the wear resistance of the inner wall of the quilted pipe, and avoiding the cause of grinding. Burns. After rolling, the surface roughness value is reduced, which can improve the mating properties.
