The net size, by buys Fang Zi to decide each kind of specification processing custom make, had many plant necessary cooperative production each metal insert, already for many petrochemical equipment Manufacturing firm necessary supply each kind of lining metal structural element, produces the product widely applies in uses in the petroleum chemical industry large-scale installment, is specially advantageous in the catalyst putting on makeup buyer wants one of equipment's lining structure major assemblies, it can enhance lining's wear-resisting performance and the intensity, the wear-resisting lining uses the hexsteel reinforcement, generally spot with carbon steel (A3F) hexsteel, like reactor and first-level, second-level cyclone separator, U tube regenerator flue and so on place, the high temperature spot with gathers (1Cr13)Hexsteel, like regenerator and first-level, second-level cyclone separator and so on place. The hexsteel is the hexagon standard which a 20*17.5 millimeter flat steel belt flushes, fixes in keeps warm on the nail terminal plate.
