Plastic rasching ring

PXZT Plastic rasching ring with reasonable price for promotion, in large stock.

PXZT plastic rasching ring is the most early-developed product in random packings. It has a simple shape with equal length at its diameter and height. The Raschig Ring is characteristic of acid-proof and heat-proof features. It can resist to the erosion of various acids and solvents except for HF and can be used under the conditions of high temperature. It is widely used in chemistry, metallurgy, gas, environmental protection areas.

Plastic random packing 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..
