Compared with solid steel such as round steel, seamless steel tube has the same bending and torsion strength and light weight. It is an economical steel. It is widely used in the manufacture of structural mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, steel scaffolding for construction. The use of seamless steel pipe to manufacture ring parts can process, save materials and processing time, such as rolling bearing rings, Jack sleeves and so on. Steel pipes are also indispensable materials for various conventional weapons, such as pipes, guns and so on. According to the shape of the section area, the steel pipe can be divided into circular pipes and special-shaped pipes. Because the circumference is equal and the circular area is large, the circular tube can transport more fluid. In addition, the ring section under the action of internal and external radial pressure, the force is more uniform, so most of the steel pipes are circular.


For special purposes, there are boiler tubes, geological pipes and tubing. 4, the specifications and appearance quality conform to the GB/T specification 4.1, the specification hot rolled tube outside diameter 32 ~ 630mm. The wall thickness is 2.5 to 75 mm. The outer diameter of cold rolling (Leng Ba) pipe is 5 ~ 200mm. The wall thickness is 2.5 ~ 12mm. Main Hydraulic Specific Steel Tube Standard DIN2391, Main Material ST35 (E235) of DIN2445, High Precision Cold-drawn Finished Products, Good Surface Quality CatalogueSteel Tube, Cold-drawn Precision Seamless Steel Tube, Cold-rolled Precision Seamless Steel Tube Seamless steel pipe, high precision seamless steel tube and precision bright seamless steel pipe.
