Professional Supplier for Heat Exchanger & Pressure Vessel
Plastic Hiflow Ring
Plastic Hiflow ring is a 3rd generation high performance tower packing which provides an optimal design of high mechanical stability, void fraction and superior mass transfer performance. The grid structure guarantees its opening pore ratio exceed 50% and bed void fraction is higher than same size’s pall ring. In addition, large fluid flux guarantee its pressure drop per square meter lower 45% than pall ring. Vertical bar staggered distribution and reinforced horizonal stripe largely improve its rigidity and strength. 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.

Physical & Chemical Properties of Plastic Hiflow Ring
Plastic tower packing can be made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinyiidene fluoride (PVDF) and Polytetrafluoroethylene (PTFE). The temperature in media ranges from 60 Degree C to 280 Degree C.
