High precision finishing of bright and precision seamless steel pipe

Process introduction: high quality carbon steel, finishing rolling, non oxidation bright heat treatment (NBK state), nondestructive testing, steel pipe inner wall scrubbed with special equipment, high pressure rinsing, rust proof oil on steel pipe as antirust treatment and dust-proof treatment at both ends.
Main features: high precision and high finish of inner and outer wall of steel pipe, no oxidation layer of steel tube after heat treatment, high cleanness of inner wall, high pressure of steel tube, cold bending, no deformation, expansion, flat and no crack, which can be used for various complex deformation and mechanical processing. Steel tube color: bright white medium with high metallic luster.
Main applications: automobile steel pipe, users of high accuracy and smoothness of steel pipe.
