15crmog material alloy pipe knowledge provided by the Xinhuai pipe industry in Shandong Liaocheng alloy steel pipe plant
15crmog material alloy pipe is a seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this kind of steel pipe contains more Cr, its high temperature, low temperature, corrosion resistance 15crmog material alloy pipe erosion performance It is not comparable to other seamless steel pipes, so the use of alloy pipes in the petroleum, chemical, power, boiler and other industries is more extensive.
When the hydrogen to be purified is passed into the side of the 15Crmog material alloy tube at 300-500°C, hydrogen is adsorbed on the wall of the 15Crmog material alloy tube. Since the 4d electronic layer of palladium lacks two electrons, it can generate hydrogen. Unstable chemical bonds (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 -10 m (20°C). (Time), so can be through the 15crmog material alloy tube, under the action of palladium, protons combine with electrons and reform hydrogen molecules, and escape from the other side of the 15crmog material alloy tube. On the surface of the 15crmog material alloy tube, the gas that is not dissociated is impermeable, so the high-purity hydrogen can be obtained using a 15crmog material alloy tube. Although palladium has unique permeation properties for hydrogen, 15crmog material alloy tube but mechanical properties of pure palladium is poor, easy oxidation at high temperatures, low recrystallization temperature, easy to deform and embrittlement 15crmog material alloy tube, it can not be used pure palladium Through the 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. For high-quality carbon structural steels and alloy structural steels used in shell-shaft tubes, hot-rolled seamless steel tubes and palladium alloys contain approximately 30% to 30% of silver and less than 5% of other components (such as gold).
