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.
Relaibe & Leek Tight
Properly installed, Pop-A-Plug® CPI/Perma plugs stay installed and are helium leak tight to 1×10 -10 cc/sec.,
Easy Sizing & Installations
