Seamless Steel Pipe For Fluid
Material: 20, Q345
Technical standard: GB/T8163
Features
Seamless steel pipe for fluid (fluid pipe) is a hollow section with no welds from beginning to end. 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. Compared with solid steel such as round steel, steel pipe is lighter in flexural and torsional strength. It is a kind of economical cross-section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, and bicycles. And steel scaffolding used in construction. 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 used for manufacturing 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 equal circumference, more fluid can be transported by the 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.
