ASTM A355 T12 T22 4"-20”Sch40 Sch60 Alloy Seamless Steel Tube Boiler Tube

.Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless pipe does not contain alloy components or there are few alloy components. Alloy pipe is widely used in petroleum, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy pipe change and are easy to adjust.
