The common materials of metal ladder ring packing are stainless steel 304, 316, 316L, 321, carbon steel and so on.

It has the advantages of high mechanical strength, acid and alkali chemical corrosion resistance, high temperature resistance, large specific surface area, high void space, low resistance and excellent anti-fouling performance. Specifically, its characteristics are as follows: reduce the pressure drop, the gap on the gas-liquid flow path is large, and the flux is large, which can effectively reduce the pressure drop. Increasing the capacity of the reactor, reducing the pressure drop allows the reactor to handle more gas and liquid, increasing the capacity. Enhance the anti-fouling ability, flow through the filler layer. Improve reaction efficiency.
