Metal Stainless Steel Ceramic PP Tower Packing Cooling Tower Pall Ring
Product description
"Yuanqiao Packing Mall" Metal Pall Ring exploit the ring feature for mass transfer and the saddle shape for lower pressure drop, has high loading and low pressure drop, Good gas-liquid distribution and high mass transfer efficiency. It is mechanically robust, lesser probability of breakage, suitable for deeper beds.
Metal Pall Ring has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency and so on.
It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable systems.
Material: Carbon Steel. SS304, 304L, 410, 316, 316L, etc.
Pall Ring Application:
It is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.(such as: Device of isolation, absorption, distillation, desorption, common decompression.)
Metal Pall Ring Benefits:
High resistance to fouling; Multiple materials available; High temperature applications; üMechanically robust, lesser probability of breakage; Good liquid/gas distribution and high mass transfer efficiency.

Pall ring features:
The opening area is about 35% of the torus area. The gas-liquid distribution and mass transfer performance in the packed bed are better than those in rasch ring due to the opening of the ring wall. Many studies have been done on its properties, so pall ring is still one of the main random packaging in use today.
