What is Plastic Pall Ring?

Plastic pall ring is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60to 150. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc.

Advantages of Plastic Pall Ring:

1. High free volume

2. Low pressure drop

3. Low mass-transfer unit height

4. High flooding point

5. Uniform gas-liquid contact

6. Small specific gravity

7. High mass transfer

8. Efficiency

Normal size (unit: Mm): D16, D25, D38, D50, D76, D90

Plastic Pall Ring is versatile. This product was advanced on the basis of Plastic Raschig Ring, and compared with it, both of them have similar cylindrical dimensions but the Plastic Pall Ring has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.chemshun as pall ring supplier, welcome to consult your packing problem.
