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

Alloy steel pipe is a kind of seamless steel pipe, its performance is much higher than the average seamless steel pipe, because this steel pipe contains more Cr, its high temperature, low temperature, Alloy Steel Pipe and Tube corrosion resistance is the performance of other seamless steel pipe than On, so the alloy steel pipe in the petroleum, chemical, power, boiler and other industries more widely used.

Hot-rolled seamless steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, geological pipe and other steel pipe.

Cold-rolled seamless steel pipe in addition to the general steel pipe, low pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, Alloy Steel Pipe and Tube oil cracking seamless steel pipe, other steel pipe, but also carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel Thin-walled steel pipe, special-shaped seamless steel pipe. Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, cold-rolled seamless pipe diameter to 6mm, wall thickness to 0.25mm, thin-walled tube diameter To 5mm, wall thickness is less than 0.25mm, cold rolling than hot-rolled size accuracy.
