Frequently Asked Questions (FAQ)
Q
What material are PTFE Pall Rings made from?
PTFE Pall Rings are manufactured from polytetrafluoroethylene (PTFE / ПТФЭ), a high-performance fluoroplastic known for its outstanding chemical resistance, low friction, and excellent thermal stability.
Q
What is the maximum operating temperature for PTFE Pall Rings?
PTFE Pall Rings can withstand operating temperatures of up to +160°C, making them suitable for demanding high-temperature chemical processing applications.
Q
What sizes are available for PTFE Pall Rings?
PTFE Pall Rings are available in a range of standard sizes: 20×20×2 mm, 25×25×2 mm, 38×38×2.5 mm, 50×50×4 mm, 65×65×5 mm, and 76×76×4 mm. Each size offers different surface area and void volume characteristics to suit specific process requirements.
Q
What are the key advantages of using PTFE Pall Rings in tower packing?
PTFE Pall Rings offer low pressure drop, high void volume, large flow capacity, excellent mass transfer efficiency, low energy consumption, and outstanding distribution performance within packed towers — all contributing to optimized column operation.
Q
How do PTFE Pall Rings compare to PP or PVDF Pall Rings in terms of chemical resistance?
All material variants — including PE, PP, РПП, ПВХ, КПВХ, and PVDF — offer good chemical corrosion resistance. However, PTFE and PVDF provide superior resistance to aggressive chemicals and higher operating temperatures (up to 150–160°C), making them the preferred choice for highly corrosive environments.
Q
What is the void volume of PTFE Pall Rings and why does it matter?
The void volume of PTFE Pall Rings ranges from approximately 92% to 94.8% depending on the size. A higher void volume means less resistance to gas and liquid flow, resulting in lower pressure drop and higher throughput capacity — which is critical for efficient column performance.
