15 CrMo Alloy Steel Pipe, DN200, SCH 40, Cold Drawn, GalvanizedPaintingCoating, High Pressure

Seamless steel tubes have hollow sections and are used in large quantities as pipelines for conveying fluid, such as pipelines for oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is a kind of economical steel with light weight when bending and torsion strength is the same. It is widely used to manufacture structural parts and mechanical parts, such as petroleum drill pipe, automobile drive shaft, bicycle frame and steel scaffold used in construction.

It is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffold used in construction. Steel pipe or all kinds of conventional weapons indispensable materials, barrel, barrel and so on are made of steel pipe. The steel pipe can be divided into round pipe and special-shaped pipe according to the shape of cross-sectional area. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, the ring section under internal or external radial pressure, the force is more uniform, therefore, most of the steel pipe is a circular pipe.
However, the circular tube also has some limitations, such as under the condition of plane bending, the circular tube is less than square, rectangular tube bending strength, some agricultural machinery skeleton, steel wood furniture and so on commonly used square, rectangular tube. According to different uses also need to have other section shape special-shaped steel pipe.
