In our understanding, the concept of seamless steel pipe is a hollow section, no seams around the strip steel. However, many people may have doubts. 

Why do we see the vast majority of seamless steel tubes as round?

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, has light weight. It is a kind of economic cross section steel widely used in the manufacturing 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 can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, such as rolling bearing ring, Jack sets 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.

However, the pipe also has some limitations, such as by plane bending conditions, the pipe is not as good as the square pipe bending strength, some farm skeleton, steel wood furniture and used the square pipe. Depending on the use of different sections of the shape of the steel pipe.
