Alloy steel pipe is an economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in building construction.
The use of alloy steel pipes to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sets, etc.
Alloy steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area.
Due to the condition that the circumference is equal, the area of the circle is the largest, and more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform, so most steel pipes are round pipes.

The main purpose of alloy steel pipe

Alloy steel pipe is used in high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. Rolled (extrusion, expansion) or cold rolling (pulling).
Alloy steel pipes have a hollow cross-section and are widely used as pipes for transporting fluids, such as pipes for transporting oil, natural gas, gas, water and certain solid materials.
