Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into seamless pipe for structure and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard of alloy tube and its industry. The alloy tube is annealed and conditioned to change its mechanical properties. To achieve the required processing conditions. Its performance is higher than the general seamless steel pipe variable utilization value, alloy tube chemical composition contains more Cr, high temperature resistance, low temperature resistance, corrosion resistance. General carbon seamless tube does not contain alloy composition or alloy composition is very little, alloy tube in petroleum, aerospace, chemical, electric power, boiler, military and other industries used more widely because the mechanical properties of the alloy tube change better adjustment.
