Product Description
12Cr2MoV alloy pipe is based on high-quality carbon structural steel, and one or several alloying elements are appropriately added to improve the mechanical properties, toughness and hardenability of steel. Products made of this type of steel usually require heat treatment (normalizing or quenching and tempering); the parts and components made of such steel usually need to undergo quenching and tempering or surface chemical treatment (carburizing, nitriding, etc.), surface Quenching or high-frequency quenching and other treatments. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use, this type of steel can be roughly divided into three types: carburizing, quenching and tempering and nitriding. ] This kind of steel is multi-rolled (forged) into round, square, flat profiles and seamless steel pipes, which are mostly used to make more important and larger-sized parts and components in mechanical products, as well as high-pressure pipes, containers, etc. This high-quality carbon structure Steel has better comprehensive mechanical properties.
Classification of high pressure boiler tubes (1) High-quality carbon structural steel grades are 20G, 20MnG, and 25MnG. (2) Alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoV, 12CrMoVG, 12Cr3MoVSiTiB, etc. (3) The commonly used 1Cr18Ni9 and 1Cr18Ni11Nb boiler tubes with rust and heat-resistant steels should be subjected to hydrostatic test, flaring and flattening test one by one in addition to ensuring chemical composition and mechanical properties. Steel pipes are delivered in heat-treated condition. In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe. Specifications and appearance quality of high-pressure boiler tubes: GB5310-95 "Seamless Steel Tubes for High-Pressure Boilers" has an outer diameter of 22-530mm and a wall thickness ranging from 20-70mm. The outer diameter of the cold drawn (cold rolled) tube is 10-108mm, and the wall thickness is 2.0-13.0mm. The principle of purifying hydrogen by 12Cr2MoV tube is that when the hydrogen to be purified is passed into one side of the 12Cr1MoV boiler tube at 300-500 ℃, the hydrogen is adsorbed on the wall of the 12Cr2MoV boiler tube, due to the lack of two electrons in the 4d electron layer of palladium. , it can form unstable chemical bonds with hydrogen (this reaction between palladium and hydrogen is reversible), under the action of palladium, hydrogen is ionized into protons with a radius of 1.5×1015m, while the lattice constant of palladium is 3.88× 10-10m (at 20°C), so it can pass through the 12Cr2MoV boiler tube, and under the action of palladium, protons combine with electrons and re-form hydrogen molecules, which escape from the other side of the 12Cr2MoV boiler tube. On the surface of the 12Cr2MoV boiler tube, the undissociated gas is impermeable, so the 12Cr1MoV boiler tube can be used to obtain high-purity hydrogen. Seamless steel pipes made of steel are widely used in pipes for hydraulic props, high-pressure gas cylinders, high-pressure boilers, fertilizer equipment, oil cracking, automobile half-shaft sleeves, diesel engines, hydraulic pipe fittings, etc.
