Seamless Square and Rectangle Steel Pipe

The seamless square and rectangle steel pipe is a strip steel with a hollow section and no seam on the rim. With a hollow section, it is widely used in pipelines of fluid transport, for instance, the transport of petroleum, natural gas, coal gas, water, and other solid materials. Compared with the solid steel pipe, and under the same resistance of twisting and bending, it is an economic section steel with lighter weight and widely applied in structure and machinery elements. Such as petroleum drill pipe, gas transmission shaft, bicycle stand, and steel scaffold which is used in building operation. We can improve the stock utilization, simplify the manufacturing process, economize materials and save the processing hour by manufacturing the steel into circular parts. For example, the rolling bearing ring and the cover of lifting jack are all made of steel pipe.

Main Component:
The raw material of seamless steel pipe is billet.
