42CrMo Seamless Tube Process

The seamless Rectangular Tube is a long strip of steel with a hollow section and no seams around it. The steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical cross-section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, and bicycles. Frames and steel scaffolding used in building construction, etc.
Round pipes also have certain limitations. For example, under conditions of plane bending, round pipes are not as strong as square and rectangular pipes in bending strength. Square and rectangular pipes are often used for some agricultural machinery skeletons, steel and wood furniture, etc.
