Seamless steel pipe has a hollow section, no joint around the strip steel. With regard to the application of seamless steel pipe, I believe we should know that it is very natural and it’s figure can be seen in all walks of life. However, what is it? You really do not know the seamless steel pipe? We look at the characteristics of   seamless steel and the uses or do we usually just ignore it ?

The steel pipe has a hollow cross section, which is used as a conduit for conveying fluid, such as oil, natural gas, coal gas, water and some solid materials. Compared with steel and round steel in solid, 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.

Manufacturing circular parts with a pipe, which can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, such as rolling bearing ring, Jack and so on, has been widely used in steel pipe manufacturing.

Steel pipe or all kinds of conventional weapons indispensable materials, gun barrels are made of steel. According to the cross-sectional area of the steel pipe can be divided into different shapes and different types of tubes.

Under the condition of the same perimeter, the circle area is the largest, and more fluid can be conveyed by the circular pipe.

In addition, when the cross section of the ring is subjected to internal or external radial pressure, the force is uniform.
