Effective, Reliable and Time Saving Method of Plugging Air Cooled Heat Exchangers

Air cooled heat exchanger tubes wear and degrade over time due to combined effects of some or all of the following

• Thermal stress
• Corrosion
• Erosion
• Vibration
• Poor Water Chemistry
• Incompatible Material Selection

Hammer in Taper Plugs is a common and conventional method used in plugging these air cooled heat exchangers. Welding of the taper plugs are almost impossible unless the header is removed.

EST Pop-A-Plug and G Series Test Guns provide the most optimal solutions to identify and plug leaking air cooled exchanger tubes.
The benefts of Pop A Plug solutions are :

• Safe - Pop A Plug will not leak or eject under pressure, more than 1.5: 1 safety factor, will not damage tube, tube joints and are also save for us in epoxy coated tube sheets
• Time Saving - EST Pop-A-Plug can be installed within minutes without any hot work or welding
• Effective and Reliable - Pop A Plug has rated pressure up to 7000 PSIG (480 Barg), helium leak tight to 1 X 10-6 cc/sec. It provides a peace of mind!
• Removable - Pop A Plugs are removeable using a simple tool such as slide hammer.
• Low installed cost- Compared to Taper Plugs, Pop-A-Plug can be installed in a fraction of time without collateral damage to the air cooled heat exchanger unit with long term increased reliability.
