Thick-walled alloy steel pipe knowledge: 15CrMo thick-walled alloy steel pipe
15CrMo alloy steel pipe is a seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature [1], corrosion resistance is the ratio of other seamless steel pipe Not so, so the use of alloy pipes in the petroleum, chemical, power, boiler and other industries is more extensive.
The principle of hydrogen purification in 15CrMo alloy steel pipe is that hydrogen is adsorbed on the 15crmo alloy pipe wall when the hydrogen to be purified is passed into the side of the 15CrMo alloy pipe at 300-500°C, due to the lack of two 4d electronic layers of palladium. Electron, which can generate unstable bonds with hydrogen (this reaction of palladium and hydrogen is reversible), under the action of palladium, hydrogen is ionized into protons with a radius of 1.5×10 15 m, and palladium has a lattice constant of 3.88 ×10-10m (at 20°C), it can pass through the 15CrMo alloy steel pipe. Under the action of palladium, protons combine with electrons and re-form hydrogen molecules to escape from the other side of the 15CrMo alloy steel pipe. On the surface of the 15crmog alloy tube, gas that is not dissociated is impermeable, so that high-purity hydrogen can be obtained using the 15crmo alloy tube. [2] Although palladium has unique permeation properties for hydrogen, pure palladium has poor mechanical properties, is easily oxidized at high temperatures, has a low recrystallization temperature, and can easily deform and embrittle 15CrMo alloy steel tubes, so it cannot be penetrated by pure palladium. membrane. By adding appropriate amounts of Group IB and Group VIII elements to palladium, a palladium alloy can be used to improve the mechanical properties of palladium. 11. Seamless steel tube for semi-axle casing (GB3088-82) is used to manufacture automotive axle bushings and drive axles. High-quality carbon structural steel and alloy structural steel for shell-shaft tubes Hot-rolled seamless steel tubes Palladium alloys, silver accounts for about 20-30%, other components (such as gold, etc.) content <5%
Steel weight formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/meter (weight per meter)
