Seamless Steel Tube is a long steel pipe with a hollow cross-section and no seams around it. Steel pipe has a hollow cross-section and is used in large quantities as a pipeline for transporting fluids, such as oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe is lighter in weight when it has the same bending and torsional strength, and is a kind of economic cross-sectional steel, widely used in the manufacture of structural and mechanical parts, such as oil transportation, stair handrails, bicycle frames, and steel scaffolding used in construction. Alloy seamless steel pipe manufacturing ring-shaped parts, can improve material utilization, simplify the manufacturing process, saving materials and processing hours, such as rolling bearing rings, jack sets, etc., has been widely used to manufacture steel pipe. Alloy seamless steel pipe or a variety of conventional weapons indispensable materials, gun barrels, barrels, etc. to steel pipe to manufacture. In addition, the circular cross-section in the internal or external radial pressure, the force is more uniform, therefore, the vast majority of seamless alloy steel pipe is a circular tube
