The main purpose of alloy steel pipe is used in power plants, nuclear power, high pressure boilers, high temperature superheaters and reheaters and other high-pressure high temperature pipes and equipment, Alloy Steel Pipe and Tube it is the use of high-quality carbon steel, alloy steel and stainless steel , By hot rolling (extrusion, expansion) or cold rolling (pull) made.

The alloy pipe has a hollow section, a large number of pipes used for conveying fluid, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel pipe is a kind of economical cross section steel which is widely used in the manufacture of structural parts and mechanical parts such as oil drill pipe, automobile drive Shaft, Alloy Steel Pipe and Tube bicycle frame and steel construction scaffolding in construction. The use of alloy steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, saving materials and processing time, such as rolling bearing rings, jack sets, etc., has been widely used to manufacture steel. Alloy steel pipe or a variety of conventional weapons indispensable materials, barrels, barrels and so on to steel to manufacture. Alloy steel pipe by cross-sectional area of the shape can be divided into tube and shaped tube. As the circumference of the same conditions, the largest circular area, with a circular tube can transport more fluid. In addition, the ring cross section in the internal or external radial pressure, Alloy Steel Pipe and Tube the force is more uniform, so the vast majority of steel pipe is a tube.

Alloy steel pipe: steel pearlite structure heat-resistant steel, at high temperature has a high thermal strength (未b 鈮 440MPa) and oxidation resistance, and has a certain resistance to hydrogen corrosion. As the steel contains a high content of Cr, C and other alloying elements, steel quenching tendency is more obvious, poor weldability.
