Application of seamless hot rolling black carbon steel high pressure boiler pipe

　　Seamless Hot Rolled Black Carbon Steel High Pressure Boiler Pipe is widely used for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel tube is a kind of economic section steel with light weight when its bending and torsional strength are the same. It is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction to manufacture circular parts. It can improve the utilization rate of materials, simplify the manufacturing process, save materials and add Working hours have been widely used to manufacture steel pipes. S
