What Is The Temperature Range of Plastic Pall Rings?

Plastic tower packing is made of those heat resistant and chemical corrosion resistant plasitc. It has features such as high void ratio, 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 operating temperature in media ranges from 60℃ to 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.

So, what is the temperature range of the plastic Pall ring? RPP, CPVC, PP, PVC, PTFE, PFA plastic material Pall ring high temperature resistance can reach how many degrees? Let's follow Chemshun Ceramics to understand the characteristics of plastic Pall ring packing parameters..

Plastic Pall ring packing material for PVC(polyvinyl chloride), polypropylene PP, PTFE(polytetrafluoroethylene), PVDF(polyvinylidene fluoride), etc., each material temperature resistance is different.

1. polypropylene PP Pall ring filler

The temperature tolerance range of PP Pall ring packing is 80 degrees Celsius. The process structure of polypropylene Pall ring improves the distribution of steam and liquid, makes full use of the inner surface of the ring, so that the gas and liquid in the packing tower can freely pass through the window.

2. PVC pall ring packing

PVC Pall ring packing has a temperature tolerance range of 110 degrees Celsius. PVC Pall ring has the characteristics of high porosity, low pressure drop and mass transfer unit height, high flooding point, full vapor liquid contact, small specific gravity, and good mass transfer efficiency.

3. Polyvinylidene fluoride ball

PVDF Pall ring packing temperature range is 150 degrees Celsius, PVDF Pall ring has good chemical resistance, high temperature resistance, oxidation resistance and so on.

4. PTFE Pall ring packing packing

PTFE Pall Ring packing The temperature tolerance range of the packing is 220 degrees Celsius. Polytetrafluoroethylene Pall ring is a high temperature resistant product in plastic packaging. Its friction coefficient is extremely low, with high porosity, high displacement point, high mass transfer efficiency, low pressure drop, three high characteristics, small specific gravity, can fully allow vapor-liquid contact, increase production efficiency.

No matter what kind of plastic Pall ring packing is used in the factory, the working temperature in the packing tower can not be higher than the maximum temperature limit of the product, otherwise the product is easy to soften, deform and even melt.
