Astm A335 P91 12" Sch40 Sch60 Sch80 Alloy Steel Seamless Pipe Hot Rolled Steel Pipe

Description
Alloy pipes have hollow sections and are used in large quantities to transport fluids, such as oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel pipe has light weight when bending and torsion strength is the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with alloy steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, Jack sleeve and so on. At present, steel pipe has been widely used to manufacture. Alloy steel pipe is also an indispensable material for all kinds of conventional weapons, barrel, barrel and so on must be made of steel pipe. Alloy steel pipe can be divided into circular pipe and special-shaped pipe according to the shape of cross-sectional area. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, the ring section under internal or external radial pressure, the force is more uniform, therefore, most of the steel pipe is a circular pipe.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.
