Manufacturing process of precision seamless steel pipe:

precise Seamless square tube Cold bending deformation is extremely low, and can be used for various complex deformation and mechanical processing. Color of square tube: white with light, also with welding. The chemical composition of precision bright tube includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P and chromium Cr.

Introduction to precision bright tube process: good carbon steel, finish rolling, non oxidizing bright heat treatment (NBK state), nondestructive testing, square tube inner wall is brushed with special equipment and washed under high pressure, square tube is treated with antirust oil for rust prevention, and both ends are sealed for dust prevention.

Main characteristics of precision bright tubes: the inner and outer walls of square tubes are of high precision and the price of high brightness steel decreases, so they are mainly used to consume the product process of pneumatic or hydraulic components. Flaring and flattening are free of cracks, the inner wall is clean, and the square tubes bear high pressure, such as the manufacturing process of precision seamless square tubes for cylinders or oil cylinders, and the manufacturing process of precision seamless square tubes without oxide layer before heat treatment, Precision bright seamless square tube is a high-precision square tube material after fine drawing or cold rolling. Since there is no oxide layer on the inner and outer walls of precision bright tubes, no disclosure under high pressure, high precision, high brightness, no deformation in cold bending, flaring, flattening, no cracks, and other small industrial chains, the manufacturing process of precision seamless square tubes can be seamless tubes with high metallic luster.
