15CrMo合金无缝管是无缝管的一种，其性能要比一般的无缝管高很多，因

15CrMo alloy seamless pipe is a seamless pipe, which is generally much higher performance than the seamless tube, such as Cr-containing steel which more, its high temperature, low temperature, corrosion resistance seamless other steel can not match, so the use of the alloy tube in petroleum, chemical, electric power, boiler and other industries widely. <br>Principle 15CrMo alloy seamless purified hydrogen is, at 300-500 deg.] C, the hydrogen to be purified into 15CrMo alloy seamless tube side, the hydrogen is adsorbed 15CrMo alloy seamless wall, since palladium 4d electron shell is missing two electrons which will produce chemically unstable hydrogen (palladium and hydrogen this reaction is reversible), under the influence of palladium, hydrogen is ionized into protons have a radius of 1.5 × 1015m, while palladium the lattice constant (when 20 ℃) 3.88 × 10-10m, it can be seamless by 15CrMo alloy, and protons combine with electrons under the influence of palladium and re-form hydrogen molecules, other alloy seamless tube from 15CrMo side escape. In 15CrMo alloy seamless surface, the gas is not dissociated impermeable, it may be utilized to obtain high purity hydrogen 15CrMo alloy seamless. Although palladium has a unique hydrogen permeation performance, but poor mechanical properties of pure palladium, easily oxidized at high temperatures, the recrystallization temperature is low, easy to make modifications and 15CrMo alloy seamless embrittlement, it can not be transmitted through pure palladium membrane . Adding an appropriate amount of palladium and the Group IB elements Ⅷ made palladium alloy, palladium may improve the mechanical properties of automobile axle casing 11. The seamless steel pipe (GB3088-82) is manufactured automobile axle casing and the drive axle axle shaft tubes of quality carbon steel and alloy hot-rolled seamless steel palladium alloys, silver, about 20-30%, content of other components (e.g., gold) is <5%. <br>[(OD - Wall Thickness) * thickness] * 0.02466 = kg / m (per meter weight)

15CrMo alloy seamless tube is a seamless tube, its performance is much higher than the general seamless tube, because this steel pipe contains more Cr, its high temperature, low temperature, corrosion resistance performance is other seamless steel pipe than, so alloy pipe in petroleum, chemical, electric power, boiler and other industries are more widely used. <br> The principle of 15CrMo alloy seamless tube purification of hydrogen is that, at 300-500 degrees C, when the hydrogen to be purified is connected to the side of the 15CrMo alloy seamless tube, the hydrogen is adsorbed on the 15CrMo alloy seamless tube wall, and due to the lack of two electrons in the 4d electron layer of the molybdenum, it can produce unstable chemical bonds with hydrogen (the chemical bonds of the moel and hydrogen) This reaction is reversible), under the action of radon, hydrogen is ionized to protons with a radius of 1.5 x 1015m, while the lattice constant of radon is 3.88 x 10-10m (at 20C), so the protons can be seamlessly connected with electrons under the action of 15CrMo, and re-formed hydrogen molecules. Escape from the other side of the 15CrMo alloy seamless tube. On the surface of the 15CrMo alloy seamless tube, the undissolved gas is not able to pass through, so a high purity hydrogen can be obtained using the 15CrMo alloy seamless tube. Although the radon has a unique transmission performance to hydrogen, but the mechanical properties of pure palladium is poor, high temperature is easy to oxidize, recrystallization temperature is low, easy to make 15CrMo alloy seamless tube deformation and brittle, so can not use pure radon as a membrane. Adding the appropriate amount of IB and VIII elements to the palladium, made into the palladium alloy, can improve the mechanical properties of the palladium 11. The seamless steel pipe (GB3088-82) for automotive half-axial casing and drive bridge shell shaft tube steaming high-quality carbon structure steel and alloy structure steel thermal seamless steel pipe alloy, silver accounts for about 20-30%, other components (such as gold, etc.) 5%. <br>(Outer diameter - wall thickness) s/wall thickness s.0.02466 s/m (weight per meter)

15CrMo alloy seamless pipe is a kind of seamless pipe, and its performance is much higher than that of general seamless pipe. Because there are more Cr in this kind of pipe, and its high temperature, low temperature and corrosion resistance performance is not comparable to that of other seamless pipes, so alloy pipe is widely used in petroleum, chemical industry, electric power, boiler and other industries.<br>The principle of hydrogen purification in 15CrMo alloy seamless tube is that when the hydrogen to be purified is introduced into one side of 15CrMo alloy seamless tube at 300-500 ℃, the hydrogen is adsorbed on the wall of 15CrMo alloy seamless tube. Due to the lack of two electrons in the 4D electron layer of palladium, it can form an unstable chemical bond with hydrogen (the reaction between palladium and hydrogen is reversible). Under the action of palladium, the hydrogen is ionized into a half proton The diameter is 1.5 × 1015 m, and the lattice constant of palladium is 3.88 × 10-10 m (at 20 ℃), so it can pass through 15CrMo alloy seamless tube, under the action of palladium, protons and electrons combine and form hydrogen molecules again, escaping from the other side of 15CrMo alloy seamless tube. On the surface of 15CrMo alloy seamless tube, the gas that is not dissociated can't pass through, so we can use 15CrMo alloy seamless tube to obtain high purity hydrogen. Although palladium has a unique permeability to hydrogen, the mechanical properties of pure palladium are poor. It is easy to oxidize at high temperature, and the recrystallization temperature is low. It is easy to deform and embrittle the 15CrMo alloy seamless pipe, so pure palladium can not be used as the permeability membrane. The mechanical properties of palladium can be improved by adding appropriate IB and Ⅷ elements into palladium alloy. 11. Seamless steel tube for automobile axle sleeve pipe (gb3088-82) is a kind of high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel tube palladium alloy for automobile axle sleeve and driving axle shell pipe. Silver accounts for about 20-30%, and other components (such as gold) account for less than 5%.<br>[(outer diameter wall thickness) * wall thickness] * 0.02466 = kg / M (weight per meter)<br>
