Alloy tube (Alloy pipe) is a kind of seamless steel pipe

Precision cold drawn seamless steel tube
Cold Drawn Seamless tubing (also known as CDS).

Alloy tube (Alloy pipe) is a kind of seamless steel pipe, its performance is much higher than the general seamless steel pipe , because this steel pipe inside containing Cr, high temperature resistance, low temperature, corrosion-resistant performance of other non-pipe joints not match, so the more extensive use of alloy tube in the petroleum, aerospace, chemical, electric power, boiler, military, and other industries.

The main use of alloy steel pipe used in power plants, nuclear power, high-pressure boiler, high temperature superheater and re-heater high pressure and high temperature piping and equipment, it is made ​​of high quality carbon steel, alloy structural steel and heat-resistant stainless steel material, hot-rolled (extrusion, expansion) or cold-rolled (pull) made​​.

The biggest advantages of alloy steel pipe
Can be 100% recycled, environmentally friendly, energy-saving, resource conservation, national strategy, national policy to encourage the expansion of the field of application of high-pressure alloy pipe. Of alloy tube total consumption accounted steel in the proportion is only half of the developed countries, to expand the field of use of the alloy tube to provide a wider space for the development of the industry. According to the Chinese Special Steel Association alloy pipe Branch Expert Group, the future needs of the average annual growth of China's high-pressure alloy pipe long products up to 10-12%.

The difference between ally steel pipe and seamless steel pipe
Alloy tube steel pipe (material) in accordance with the production of materials used to define the name suggests is alloy tube; seamless pipe steel pipe in accordance with the Production (seam seamless) to define, distinguish it from seamless pipe seam pipe, longitudinally welded pipes and spiral.
