Application of Seamless steel tube

Seamless steel pipes are very versatile. The general seamless steel pipe is made of common carbon structural steel, low alloy structural steel or alloy structural steel with the largest output. It is mainly used as the pipe or structural part for conveying fluid. . 2, there are three different supply modes according to the purpose: A, supply according to chemical composition and mechanical properties; B, supply according to mechanical properties; C, supply according to hydrostatic test. The steel supplied according to class A and B can bear both liquid pressure and hydrostatic pressure test. 3. Seamless tubes for special purpose boilers, chemical power, geological seamless tubes and various seamless tubes for petroleum.



Seamless steel pipe has a hollow part and a large number of pipes for conveying fluid, such as those for transporting oil, natural gas, gas, water and some solid materials. Compared with steel bar and other solid steel, it has the same torsional strength and light weight, so it is an economic steel.



It is widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold. It can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, and steel pipe has been widely used in manufacturing.
