Introduction of alloy steel pipe

Alloy pipes have hollow sections and are widely used as pipelines for conveying fluids, such as fire oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy steel pipe has lighter weight when its bending and torsional strength is the same. Alloy steel pipe is an economic section steel, which is widely used to manufacture structural parts and mechanical parts, such as fire oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring parts with alloy steel pipe can improve the utilization rate of raw materials, simplify the manufacturing process, and save raw materials and processing hours, such as rolling bearing ring, jack sleeve, etc. at present, steel pipe has been widely used for manufacturing.

Alloy steel pipe is also an indispensable raw material for all kinds of old-fashioned weapons. Alloy steel pipe can be divided into round pipe and special-shaped pipe according to different cross-sectional area and style. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, when the ring section encounters internal or external radial pressure, the force is more uniform. Therefore, most steel pipes are round pipes.


Alloy steel pipe has good mechanical function. It is mainly used in power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters, reheaters and other high-pressure and high-temperature pipelines and buildings. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel through hot rolling (extrusion, expansion) or cold rolling (drawing). The biggest sweetness can be 100% recycled, which is in line with environmental protection, energy conservation The national strategy of saving resources and the national policy encourage the expansion of the application field of high-pressure alloy pipe.
