Expanded PTFE (ePTFE) is widely used in flange applications due to its exceptional chemical resistance, durability, and ability to create leak-proof seals even in harsh environments. It is commonly converted into gaskets that accommodate worn or damaged flanges, ensuring long-term reliability and reducing maintenance costs. ePTFE gaskets are suitable for various flange types, including steel, plastic, enamel glass, and PTFE or rubber-lined flanges, making them ideal for chemical processing, pipelines, and other industrial applications where corrosion resistance and high-temperature stability are critical. Their ability to withstand extreme pressures and aggressive chemicals while minimizing friction and operational downtime makes them a preferred choice for demanding flange sealing solutions.
Key Points Explained:
-
Primary Use as Gaskets
- Expanded PTFE is most commonly converted into gaskets for flange applications.
- These gaskets are particularly effective for sealing worn, damaged, or non-parallel flange surfaces, ensuring a tight, leak-proof seal.
-
Advantages in Flange Applications
- Chemical Resistance: ePTFE withstands aggressive chemicals, making it ideal for corrosive environments in industries like chemical manufacturing.
- High-Temperature Stability: It can endure temperatures up to 260°C without degrading, ensuring reliability in high-heat applications.
- Pressure Resistance: ePTFE gaskets can bear extreme flange and bolt loads without blowing out, maintaining seal integrity under high pressure.
- Durability: Reduces maintenance costs and operational downtime by providing long-term sealing solutions.
-
Compatibility with Various Flange Types
- Works effectively with:
- Steel flanges
- Plastic flanges
- Enamel glass flanges
- PTFE or rubber-lined flanges
- Especially beneficial for flanges with surface imperfections or misalignment.
- Works effectively with:
-
Additional Safety and Performance Benefits
- Non-Toxic and Hygienic: Suitable for applications requiring cleanliness, such as food processing or pharmaceuticals.
- Low Friction: Minimizes wear on flange surfaces, extending equipment lifespan.
- Customizable Porosity: Available in low, medium, or high densities to suit specific sealing requirements.
-
Specialized Applications
- Used in PTFE envelopes or bore liners to protect pipe gaskets from chemical attack.
- Ideal for chemical transport systems, valves, and other critical sealing components where leakage prevention is paramount.
-
