Introduction of seamless steel pipe

　　Seamless steel pipe is a kind of long steel with hollow section and no joint in the surrounding area. Seamless steel pipe has a hollow section, which can be used as a pipe for conveying fluid, such as pipelines, such as oil, natural gas, gas, water and some solid materials. Compared with other solid steel DIN 15CrMo galvanized seamless steel pipe, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold. The annular parts made of seamless steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, Jack sets and so on. Now they are widely used for manufacturing steel pipes. Steel pipe or all kinds of conventional weapons indispensable materials, gun barrels are made of steel.
