Alloy tube is mainly used for low and medium pressure boiler (working pressure is generally not more than 5.88Mpa, working temperature below 450 ℃) of heating surface tubes; for high-pressure boilers (above 9.8Mpa working pressure in general, the working temperature of 450 ℃ ~ 650 between ℃) of heating surface tubes, economizer, superheater, reheater, petrochemical industrial pipe High Alloy Pipe Grade:. 15CrMoG, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, SA210A1, SA210C, SA213 T11, SA213 T12 , SA213 T22, SA213 T23, SA213 T91, SA213 T92, ST45.8 / Ⅲ, 15Mo3,13CrMo44,10CrMo910 etc. standard alloy tube with a hollow cross-section, a large number of pipes used for transporting fluids, such as transportation of oil, gas, gas, water , machining of large diameter pipe, and some solid materials, pipes and so on. Compared to other alloy steel pipe and solid steel bar, the same torsional strength in bending, lighter, alloy steel pipe 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 using steel scaffolding. The ring with a steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving materials and processing time, such as bearing rings, jack sets, is currently widely used to make steel. Steel pipe or a variety of conventional weapons indispensable material, barrel, barrel, etc. to make steel. Different shapes steel pipe cross-sectional area can be divided into tube and shaped tubes. Because in the perimeter of equal conditions, the largest area of ??a circle 45 # large diameter steel pipe, with a circular tube can carry more fluid. Furthermore 40cr large diameter steel pipe, the circular cross section to withstand internal or external radial pressure, the force is uniform, so q345 large diameter steel pipe, the vast majority of pipe is pipe. There are large diameter alloy tube alloy tube, thick-walled alloy tube, high alloy pipe, alloy flanges, alloy elbow, P91 alloy pipe and seamless steel pipe, another fertilizer tube is also very common. 20mn large diameter steel pipe, large diameter steel pipe, Yantai, Liaocheng virtue by virtue Pipe Industry Co., Ltd.
