Alloy pipe is a kind of seamless steel pipe, which is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. Mainly different from the production standard and industry of alloy tubes, annealing and tempering alloy tubes change their mechanical properties. Achieve the required processing conditions. Its performance is higher than that of common seamless steel pipe, and its chemical composition contains more Cr, so it has high temperature resistance, low temperature resistance and corrosion resistance. Common carbon seamless pipe contains no alloy components or few alloy components. The reason why alloy pipes are widely used in petroleum, aerospace, chemical industry, electric power, boiler, military industry and other industries is that the mechanical properties of alloy pipes are changeable and easy to adjust.
