Gallagher Fluid Seals is often presented with unique sealing challenges. It's no surprise, considering this is our 65th year in business.
One of our customers, a global composite tank manufacturer, came to GFS with a HUGE request. And we mean "HUGE" literally.
Challenges of Large Diameter Gaskets
Their fabricated composite tanks needed to withstand media and temperature fluctuations to treat sewage at customer sites across the world.
The caveat: Sewage digestion tanks can range in sizes from 10ft in diameter up to 100+ ft diameters. In this case, our customer's tank sizes were 80 ft diameter.
There are challenges when manufacturing large diameter gaskets; In this case, the challenges were related primarily to material fabrication.
Here are the application details for these sewage digestion tanks:
- Internal and External Temperature: -20°F to 110°F
- Hydrogen sulfide concentration: 125 ppm
- Internal vacuum: 2 in. H2O
- IBC Occupancy Risk Category: III
Solution
Gallagher engineers reviewed the parameters and developed an interlocking EPDM gasket that allowed for sealing of the large containment vessel. This EPDM gasket was successful in helping seal the 80 ft diameter sewage digestion tanks and excelled in meeting the application needs for the project.
