Alloy steel pipe has a hollow section, a lot of alloy pipes are used as fluid conveying pipeline, use for conveying petroleum, nature gas, gas, water and other solid material. Compared with the round steel pipe and other solid steel pipes, the weight of alloy steel pipe is lighter than others at bending strength in the same bending moment, it is an economical section steel. Widely use for make the structural parts and mechanical parts, such as petroleum drilling pipe, car drive shaft, bicycle frame, and steel scaffolding use for building construction. Use the alloy steel to make ring parts can improve the material utilization, simplify the manufacturing process, save material and working hours, such as rolling bearing rings, jackets are widely use the steel to manufacture.
The main purpose of alloy steel pipe is for power plant, nuclear power, high-pressure boiler, high temperature super-heater, re-heater and other high press, high temperature pipeline and equipment. It is manufacture with high-quality carbon steel, alloy structural steel and stainless heat-resistant steel after hot rolling (extrusion, expansion) or cold rolling (pulling).
The best advantage of alloy steel pipe is can be 100% recycled, it is in line with the national strategy of environmental protection, energy saving and resources conservation, the national policy encourages the application of high-pressure alloy steel pipe.
