Product Details

key word : Seamless Steel Pipe

Description

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, boilerand other industries.

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.

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.

Alloy steel pipes are ideally suitable for chemical, petrochemicals, and other energy-related applications.
