The main use of alloy steel pipe used in power plants, nuclear power, high-pressure boiler, high temperature superheater and re-heater high pressure and high temperature piping and equipment, it is made of high quality carbon steel, alloy structural steel and heat-resistant stainless steel material, hot-rolled (extrusion, expansion) or cold-rolled (pull) made.

Alloy steel pipe of the biggest advantages

Can be 100% recycled, environmentally friendly, energy-saving, resource conservation, national strategy, national policy to encourage the expansion of the field of application of high-pressure alloy pipe. Of alloy tube total consumption accounted steel in the proportion is only half of the developed countries, to expand the field of use of the alloy tube to provide a wider space for the development of the industry. According to the Chinese Special Steel Association alloy pipe Branch Expert Group, the future needs of the average annual growth of China's high-pressure alloy pipe long products up to 10-12%.

Alloy pipe and seamless pipe and different

Alloy tube steel pipe (material) in accordance with the production of materials used to define the name suggests is alloy tube; seamless pipe steel pipe in accordance with the Production (seam seamless) to define, distinguish it from seamless pipe seam pipe, longitudinally welded pipes and spiral.

Alloy tube material roughly :16-50Mn, 27SiMn, 40Cr ,12-42CrMo 16Mn 12Cr1MoV T91 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo etc.

Alloy pipe standards

Alloy tube with a hollow cross-section, for a large number of pipes conveying fluid, such as the transportation of oil, natural gas, coal gas, water and some solid materials pipeline. Compared to solid steel alloy steel tubes and round steel in flexural torsional strength the same, lighter, alloy steel tube is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive transmission shafts, bicycle frames and construction used in steel scaffolding. Alloy steel pipe manufacturing ring parts can improve material utilization, simplify the manufacturing process, saving material and processing time, such as rolling bearing rings, jack sets, has been widely used to make steel. Alloy steel pipe, or a variety of conventional weapons is an indispensable material barrel, barrel must make steel. Alloy steel tubes with different shape of the cross-sectional area can be divided into the tube and Yixingguan. Since the equal conditions in the perimeter area of ​​a circle with a round pipe can deliver more fluid. Addition, when subjected to internal or external radial pressure, the annular cross-sectional force more uniform, therefore, most of the pipe is circular tube.
