Liaocheng Shenhua provides: Precision light tube meaning, process technology and purpose Precision light tube is a kind of high-precision steel tube material after finishing or cold rolling. Due to the fact that the inner and outer walls of precision bright tubes have no oxide layer, withstand high pressure, no leakage, high precision, high smoothness, no deformation due to cold bending, no flaring, no flat cracks, etc., they are mainly used for the production of pneumatic or hydraulic components such as cylinders or The cylinder can be seamless or welded. The chemical composition of the precision bright tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. Precision bright tube process description: High-quality carbon steel, finish rolling, non-oxidation bright heat treatment (NBK state), non-destructive testing, steel pipe inner wall scrubbing with special equipment and high-pressure washing, rust-proof oil on the steel pipe for rust-proof treatment, and both end caps for dustproof treatment. Precision light tube main features: The inner and outer walls of the steel tube have high precision and high finish. After the heat treatment, the steel tube has no oxide layer, and the inner wall has high cleanliness. The steel tube is subjected to high pressure, the cold bend is not deformed, and the flaring and flattening are free of cracks, and can be used for various complicated deformations and mechanical processing. Steel color: bright in white, with high metallic luster. Precision light tube main use: Automobiles, machinery parts and other machinery with high requirements for the accuracy and finish of steel pipes. Nowadays, precision steel pipe users are not only users with higher requirements on precision and finish. Due to the precision of precision light tubes, tolerances can be maintained at 2- to 8-wires, so many machining users need to save labor, material, and time. Loss, the seamless steel tube or round steel is slowly turning into a precision bright tube.
