What is the use of seamless steel pipe what is its purpose

Seamless steel pipe is made of solid tube after perforation without seams around the pipe, in accordance with the different cross-sectional shape, is divided into round and special-shaped tube. Since the circle has the largest area under the same circumstance, the circular pipe can deliver more liquid. At the same time, the circular cross-section is subjected to more uniform stress when subjected to internal or external radial pressure, so that most of the steel pipe Is a tube. However, the tube also has some limitations, such as in the plane by the curved conditions, the tube is not as good as the square tube and rectangular tube bending strength, so some agricultural machinery skeleton, steel and wood furniture will be based on different uses or functions , Using exotic pipe. Compared with welded steel pipe, seamless steel pipe production processes and more difficult, high cost, but also often prone to uneven wall thickness and surface quality defects. However, some thick-walled pipe, thin, very fine diameter pipe, and performance requirements have special requirements of the pipe, the current method can only be used to produce seamless.
 
Because of seamless steel tubes and round bars and other solid steel, bending torsional strength at the same time, the smaller, is an economical section of steel, it is widely used in the manufacture of structures and various mechanical parts, such as oil drill pipe, Car transmission, bicycle frame and steel scaffolding used in construction. Seamless pipe manufacturing ring parts, can improve the utilization of materials, simplifying the manufacturing process, saving material processing hours, such as the production of rolling bearing rings, jackets and so on. In addition, the pipe can be used to produce routine instruments, such as barrel, barrel and so on. Another company can be customized processing all kinds of special-shaped seamless steel tubes such as hexagonal seamless steel tubes, cylindrical hexagonal seamless steel tubes, triangular seamless steel pipe, diamond seamless steel pipe, rectangular seamless steel pipe, square seamless steel pipe.
