〣Description of 15CrMoG high pressure boiler tube


15CrMoG high pressure boiler tube is alloy high pressure boiler tube, alloy structural steel. The seamless steel pipe made of this kind of steel is widely used in hydraulic prop, high pressure gas cylinder, high pressure boiler, fertilizer equipment, oil cracking, automobile half shaft sleeve, diesel engine, hydraulic pipe fittings and other pipes.


On the basis of high quality carbon structural steel, appropriate addition of one or several alloying elements, used to improve the mechanical properties, toughness and hardenability of steel. Products made from such steels are usually subjected to heat treatment (normalizing or tempering); Before use, the parts made of it usually need to undergo tempering or surface chemical treatment (carburizing, nitriding, etc.), surface quenching or high-frequency quenching. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use of different, this kind of steel can be roughly divided into carburizing, tempering and nitriding steel three.


This kind of steel is made into round, square, flat profiles and seamless steel tubes by multi-rolling (forging). It is mostly used to make the parts, components, high pressure pipes, vessels and so on, which are important and large in mechanical products. This high-quality carbon structural steel has better comprehensive mechanical properties.


High pressure boiler tube specifications and appearance quality: GB5310-2008 "Seamless steel pipe for high pressure boiler" hot rolled tube diameter 22 ~ 530mm, wall thickness of 20 ~ 70mm. Cold drawn (cold rolled) pipe outer diameter of 10 ~ 108mm, wall thickness of 2.0 ~ 13.0mm.


The principle of hydrogen purification in 15CrMoG high-pressure boiler tube is that when hydrogen to be purified is passed into the side of 15CrMoG alloy steel tube at 300-500 ℃, hydrogen is adsorbed on the wall of 15CrMoG alloy tube. Due to the lack of two electrons in the 4d electron layer of palladium, it can form an unstable chemical bond with hydrogen (this reaction between palladium and hydrogen is reversible). Under the action of palladium, hydrogen is ionized into proton with a radius of 1.5×1015m, while the lattice constant of palladium is 3.88×10-10m (at 20℃). Therefore, through the 15CrMoG alloy steel tube, proton can combine with electrons and form hydrogen molecules again under the action of palladium, and escape 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 impenetrable, so the 15CrMoG alloy tube can be used to obtain high purity hydrogen.
