polypropylene pall rings

 

Plastic Pall Ring

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.

Advantages of Plastic Pall Ring:

• 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

Application of Plastic Pall Ring:

Absorption, scrubbing, and stripping services. Versatile alternative to metal Pall rings. A variety of different sizes of products provide the ability to optimize capacity and efficiency based on different application requirements, and the application temperature in media ranges from 60 to 150 ℃.

Materials:

Plastic tower packings are made of 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).
