Seamless Square Tube



Product Description

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.

Steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Due to the condition that the circumference is equal, the area of the circle is the largest, and more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform, so most steel pipes are round pipes.
