Seamless steel tube is very versatile. The general purpose
seamless steel pipe is made of common carbon structural steel, low alloy structural steel or alloy structural steel with the most output, mainly used as the pipe or structural part for transporting fluid. .2, according to the use of different sub-three types of supply: a, according to the chemical composition and mechanical properties of supply; b, according to the mechanical properties of supply; c, according to hydrostatic test supply. According to a, b class supply of steel, as used to withstand liquid pressure, but also to carry out hydrostatic test. 3, a special purpose seamless tube Boiler with a seamless tube, chemical power, geological seamless steel pipe and oil with a variety of seamless tubes.
Seamless steel tubes have a hollow section, a large number of pipes used to transport fluids, such as pipes for transporting oil, natural gas, coal gas, water and certain solid materials. Steel and bar and other solid steel compared to the same torsional bending strength at the same time, light weight, is an economical section of steel.
Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automotive drive shafts, bicycle racks and steel scaffolding used in the construction of steel pipe manufacturing ring parts, can improve material utilization, simplifying the manufacturing process, saving materials and processing Working hours, steel pipes have been widely used to manufacture.
