Alloy steel pipes are mainly used in power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters, reheaters and other high-pressure and high-temperature pipes and equipment. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel, and are hot rolled (extruded, expanded) or cold rolled (drawn).
Alloy pipes have hollow sections and are widely used as pipelines for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy steel pipe is lighter in weight when the bending and torsional strength is the same. Alloy steel pipe is a kind of steel with economic section, which is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring parts with alloy steel pipes can improve the material utilization rate, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes have been widely used for manufacturing. Alloy steel pipe is also an indispensable material for various conventional weapons, and the barrel and barrel of the gun are made of steel pipe. Alloy steel pipes can be divided into round pipes and special-shaped pipes according to the shape of cross section. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by using circular pipes. In addition, when the ring section is subjected to internal or external radial pressure, the stress is relatively uniform. Therefore, most steel pipes are round pipes.
