The seamless steel pipe for fluid (fluid pipe) is a kind of hollow section with no welds from beginning to end. Compared with solid steel such as round steel, steel pipe has a lighter weight when the bending and torsion strength is the same, and it is a kind of economical cross-section steel.
use:
The steel pipe has a hollow section and is used as a pipe for transporting oil, natural gas, gas, water and certain solid materials in large quantities. It is also widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.
advantage:
The use of steel pipes to manufacture ring-shaped parts can increase the utilization rate of materials, simplify the manufacturing process, and save materials and processing man-hours. For example, rolling bearing rings, jack sleeves, etc., have been widely manufactured with steel pipes. Steel pipes are also an indispensable material for various conventional weapons. Gun barrels and barrels are all made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported with a circular tube. In addition, when the ring section bears internal or external radial pressure, the force is relatively uniform. Therefore, most steel pipes are round pipes.
