1.Product Description
Plastic Covering Ball 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 60°Cto
150°C. 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.
