Alloy steel pipes stock

Alloy steel 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​​.

Backed by a team of professionals and sound production unit, we have been able to provide our clients with an impeccable Alloy Steel Seamless Boiler Pipe.

Our globally recognized inventory is complete with:

Alloy pipes specification and Size

Alloy steel is a series of alloy which its main content is steel. To add different metal elements with different ratios in steel can change the mechanical properties of alloy steel.

The Advantages Of Alloy Steel Pipe

The alloy steel pipe adopts high quality carbon steel, alloy structural steel and stainless & heat resisting steel as raw material through hot rolling or cold drawn to be made.

The main applications of alloy steel pipe is power station, nuclear power plant, high pressure boiler, high temperature superheater and re-heater coil etc. of high temperature pipeline and equipments.

The advantages of alloy steel pipe: 100% recycled, it is suitable for the national strategy of environmental protection, energy-saving and resource-saving. Therefore, the national policy encourages the expansion of the high pressure alloy steel pipe applications.

At present, the proportion of the total alloy steel tube is half of the developed countries. The applications of alloy steel pipe provide a broad space for the industry development. According to the research of the China association of special steel alloy pipe expert group, our country’s high pressure alloy steel pipe material demand grows by an average of up to 10-12%.

Developed with advance technology, these products are in compliance with the defined parameters of the industry. These offered alloy pipes are available with us in divergent sizes and specifications meeting divergent demands of the clients.
