Alloy seamless steel pipe

Alloy steel seamless pipe is ideally suitable for chemical, petrochemicals and other energy-related applications. It has characteristics of high corrosion resistance and can be used in a wide range of industrial sectors.

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 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%.
