15CrMoG high-pressure boiler tube knowledge provided by Chongqing Fengshuo Weiye
15CrMoG high pressure boiler tube is an alloy high pressure boiler tube, alloy structural steel. Seamless steel tubes made of such steel are widely used in hydraulic props, high-pressure gas cylinders, high-pressure boilers, fertilizer equipment, petroleum cracking, automotive axle bushings, diesel engines, and hydraulic pipe fittings.
15CrMoG high pressure boiler tube weight formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg / meter (weight per meter)
The principle of hydrogen purification in the 15CrMoG high-pressure boiler tube is that, when the hydrogen to be purified is passed into the side of the 15CrMoG alloy steel tube at 300-500°C, hydrogen is adsorbed on the wall of the 15CrMoG alloy tube due to the lack of two 4d electron layers of palladium. Electrons, 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 the lattice constant of palladium is 3.88×10-10m (at 20°C), so it can pass 15CrMoG alloy steel pipe, under the action of palladium, protons combine with electrons and re-form hydrogen molecules, which escapes from the other side of the 15CrMoG alloy tube. On the surface of the 15CrMoG alloy tube, the gas that has not been dissociated is impermeable, so the 15CrMoG alloy tube can be used to obtain high purity hydrogen.
