Pop-A-Plug® Air-Cooled Heat Exchanger Tube Plugging System Fin Fan Coolers
Tube leaks in ACHE units (also called fin fan coolers) are difficult to identify and repair due to the limited access to the tube sheet through the plug sheet.
Typically when leaks in the tubes are identified they are plugged by using tapered hammer-in plugs, or in higher pressure ACHE units, the plugs have to be welded in place. In both cases, the damage frequently occurs to the tube sheet, plug sheet, and/or adjacent tubes.
Pop-A-Plug® Air Cooled Heat Exchanger Tube Plugging System offers significant advantages over hammer-in or welded plug applications for the following reasons:
- Average installation time: 2 minutes per plug
- No weld permits required
- No expert welders required
- Consistent and repeatable installation
- No damage to plugsheet threads, tubesheet, or adjacent tubes.
- Permanent sealing solution with removability option

Operational Benefits
Pop-A-Plug® CPI/Perma plugs are conservatively rated for 1,000 psi (68.9 Bar) service.
Properly installed, Pop-A-Plug® CPI/Perma plugs stay installed and are helium leak tight to 1×10 -10 cc/sec.
Pop-A-Plug® CPI/Perma plugs are simple mechanical plugs which can be installed hydraulically in minutes without damaging the tube, tubejoint or tubesheet. Installs using standard Pop-A-Plug System Ram Package or Manual Installation Tool.
Properly installed, Pop-A-Plug® CPI/Perma plugs stay installed and are helium leak tight to 1×10 -10 cc/sec.
Use PAP Tube Cleaning Brush to prepare the tube end, gauge the tube with a PAP Go / No-Go Gage, select the matching plug size and POP. Pop-A-Plug® CPI/Perma plugs may be removed using the Pop-A-Plug Removal Tool when its time to retube.
Always match Pop-A-Plug® CPI/Perma plugs to the tube material. Pop-A-Plug® CPI/Perma plugs are available for immediate shipment in stainless steel 316, carbon steel and brass. Titanium and other alloys can be supplied by request – Contact factory.
When ordering, specify tube OD and wall thickness or measured tube ID, tube material, tubesheet material if plug will be installed directly into tubesheet, maximum pressure and temperature, type of tube to tubesheet joint (rolled, welded, etc.) and condition of tubes and age of heat exchanger. Specifications subject to change.
Manufactured under a Quality Assurance Program certified to ISO 9001 and several U.S. nuclear power industry standards including ANSI N45.2, NQA-1, 10CFR 50 Appendix B, and 10CFR 21.
