The Carbon Structural Tube is a hollow section customized carbon steel tube with no welds from beginning to end. When the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Using Carbon Structural Tube to make square parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing time. The ASTM A106 Carbon Structural Tube has a hollow section and is used for Pipelines for conveying oil, natural gas, natural gas, water, and certain gaseous or liquid materials. Compared with solid steel such as round steel, carbon seamless steel pipe is lighter in weight with the same bending and torsional strength. It is an economical section steel and is widely used in the manufacture of structural and mechanical parts such as oil drill pipes, automobile transmission shafts, and bicycles.
