Stainless Steel
Pall Ring
Overview
Stainless steel pall ring features a cylindrical structure made of thin metal sheet with punched out windows and inward bending tabs. This particular design greatly boosts performance of the packing, with not only minimal pressure drop, greater loading capacity, throughput, but also efficiency. Thus, they are excellent for applications at atmospheric pressure and under vacuum that require low pressure drop and also a high capacity. Its geometry also facilitates improved flow, contributing to better distribution and mass transfer efficiency of liquid and gas.
Stainless steel pall rings are versatile. They are easily wettable and have a high resistance to fouling and corrosion. Being mechanically robust, stainless steel pall rings are suitable for high temperature applications and also ideal for deeper beds.
