Metal Pall rings can be manufactured using carbon steel, aluminum alloy, and various grades of stainless steel such as SS 304, 304L, 410, 316, and 316L, depending on operational and corrosion-resistance needs.
Key advantages include low wall thickness, high heat resistance, high void fraction/free volume, significant operating capacity, low pressure drop, and superior mass transfer separation efficiency compared to conventional packing.
It is predominantly applied in rectification towers under vacuum, absorption systems, scrubbing units, and stripping operations within the petrochemical, chemical fertilizer, and environmental protection sectors.
Yes, metal Pall rings are particularly optimized for vacuum rectification towers where treating thermosensitive, easily polymerizable, decomposable, or cokable media demands minimal pressure drop.
Standard dimensions include 16×16×0.3mm, 25×25×0.3mm, 38×38×0.4mm, 50×50×0.5mm, 76×76×0.6mm, and 89×89×0.7mm, each offering different surface area and bulk density metrics.
Yes, Chemxin metal Pall rings are engineered for versatile performance across both deep vacuum towers and high-pressure towers, significantly expanding operational capacity compared to conventional column trays.
