PTFE Pall Ring

The PTFE Pall Ring is a high-performance random packing material made from pure Polytetrafluoroethylene (PTFE), designed for demanding chemical separation and scrubbing processes. With its distinctive open-wall structure and high void ratio, the PTFE Pall Ring ensures superior mass transfer efficiency and minimal pressure drop across packed columns. Compared to traditional Raschig rings or ceramic packing, PTFE Pall rings deliver enhanced resistance to corrosion, high temperatures, and aggressive chemical environments. Their non-stick and low-friction properties also help prevent fouling and scaling, extending operational life and reducing maintenance frequency.

FAQ

Q1: What is a PTFE Pall Ring used for?

A: PTFE Pall Rings are used in packed columns for mass transfer applications such as gas absorption, stripping, and distillation, especially in corrosive chemical environments.

 

Q2: Is the PTFE Pall Ring suitable for high temperatures?

A: Yes. PTFE can withstand continuous temperatures up to 260°C, making PTFE Pall Rings ideal for high-temperature chemical processes.

 

Q3: What makes the PTFE Pall Ring better than metal or ceramic packing?

A: PTFE offers excellent corrosion resistance, lower weight, and a non-stick surface-ideal for processes involving aggressive or sticky media.

 

Q4: Can you provide custom sizes of PTFE Pall Ring?

A: Yes, we can manufacture custom diameters and wall thicknesses based on your process requirements.

 

Q5: Is the PTFE Pall Ring FDA-approved for food applications?

A: Yes, on request, we offer PTFE Pall Rings made from FDA-compliant virgin PTFE.

 

Q6: How do you ensure the quality of your PTFE Pall Ring?

A: We follow a strict ISO 9001-based QC process, including dimensional checks, spark testing, and material certification for every batch.

 

Q7: Can I get a free sample before placing a bulk order?

A: Yes, samples of standard PTFE Pall Ring sizes are available upon request.

 

Q8: How long is the delivery time for a bulk order?

A: Generally, it takes 7–15 working days, depending on the quantity and customization level.
