What is GB 8163 steel pipe? What is its main uses?

GB 8163 steel pipe is a seamless steel pipe for fluid transportation (GB/T8163-2018), which is a general seamless steel pipe used to transport water, oil, gas and other fluids.

GB 8163 steel pipe (fluid pipe) is a kind of hollow section with no weld from the beginning to the end. The steel pipe has a hollow section, which is widely used as a pipeline for transporting oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel tube is a kind of economic section steel, which is widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction.

Using steel pipe to make ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing ring, jack sleeve, etc. at present, steel pipe has been widely used for manufacturing. Steel pipe is also an indispensable material for all kinds of conventional weapons. Steel pipe is used to manufacture barrel and barrel.

According to the different cross-sectional shapes, steel pipes can be divided into circular pipes and special-shaped pipes. Because the circle area is the largest under the condition of the same circumference, more fluid can be transported by the circular tube. In addition, when the circular section bears the internal or external radial pressure, the force is relatively uniform. Therefore, the vast majority of steel pipes are circular pipes.
