The Fast and Safe Way to Seal Leaking Heat Exchanger, Condenser, and Boiler Tubes
- Rated up to 1000 psi (68.9 Bar)
- Suitability and type tested by TUV
- Safer alternative to tapered pin and elastomer plugs
- Helium leak-tight to 1x10-6 cc/sec
Taper pins can turn into lethal projectiles — and that can pose a real safety hazard for your workers. Now you can eliminate this danger with EST’s Pop-A-Plug® CPI/Perma Plug. These mechanical tube plugs are resistant to thermal cycling and able to provide a seal that’s helium-leak tight, EST’s Pop-A-Plug® CPI/Perma Plug installs using controlled force. This protects against damage to tubesheet ligaments and adjacent tubesheet joints, extending the life of your heat exchanger and reducing costs when you need to retube. What’s more, the Pop-A-Plug® CPI/Perma Plug takes only seconds to install. Its broad expansion range fits multiple gauges, so you need to keep fewer plugs on hand — reducing inventory and cutting costs.
The Pop-A-Plug® CPI/Perma Plug is part of a high performance tube plugging system. Tube preparation is the second component. EST removes all tube prep uncertainty by supplying a kit of brushes to cover the Pop-A-Plug® CPI/Perma Plug's entire expansion range. Other materials are available on a consult factory basis.
