Metal moment saddle ring also called the los hicks ring, integrated the annular packing and saddle packing advantages. The structure of metal saddle ring packing in the saddle on the basis of increased ring bar, to avoid the overlapping, guarantee a certain strength and just sex, out of a few small claw, increased the gas liquid agitation, strengthened the mass transfer, resulting in a unique performance. Use a metal moment saddle ring can increase the production rate, reduce the energy consumption and cost, improve the separation efficiency. Metal moment saddle ring packing is metal step ring, pall ring throughput maximum, minimum pressure drop, the mass transfer efficiency is the highest. Metal moment saddle ring packing it has lower pressure drop, throughput efficiency is high, the packing layer fluid redistribution performance is good wait for a characteristic. Metal moment saddle ring packing used in crude oil vacuum distillation, high vacuum distillation, olefin separation, isomer separation, extraction distillation, etc. Metal moment saddle ring performance parameters: Specifications × × diameter high thick Mm accumulation number N/m&sup 3; Specific surface area M&sup 2; / m&sup 3; Accumulation severe m&sup
