A Superior Tube Plugging Method


When plant chemistry is off due to leaking tubes in a condenser, typically plants will choose one of the following options:

  • Run until your next scheduled outage or
  • Go into an unplanned outage

The decision is normally made depending on the severity of the tube leak. In the case of a minor tube leak, chemicals can be added to offset the disparity in plant chemistry until the plant is able to reach a scheduled outage. Immediate shutdowns are usually required for more severe tube leaks. In either case, it’s imperative that you have a reliable tube plugging solution at your fingertips!

Choosing temporary friction fit tapered and elastomer/polymer plugs to repair leaking condenser tubes shouldn’t be an option. EPRI Condenser In-leakage1 report describes in detail the importance of choosing a reliable, permanent, and leak-tight tube plug for the life of the condenser and the costly mistake of using an unreliable plug. The report states, “the expense associated with controlling persistent water in-leakage as a result of tube and plug leaks may be many times the cost of even the most expensive plug”. Avoid the added and unnecessary cost by choosing a permanent tube plugging method!

Pop-A-Plug® is the reliable and permanent tube plug you need! 

Pop-A-Plug Tube Plugs are pressure rated up to 7000 PsiG (483 BarG) and meet all guidelines contained in the EPRI Condenser In-Leakage report, offering a mechanical solution to seal leaking condenser tubes. Pop-A-Plug Tube Plugs also accommodate a broad range of tube sizes and materials. Their ability to outperform temporary plugs in low, medium, and high pressure applications make them a first choice for power plants looking to maximize plant uptime and prevent disparities in plant chemistry.

Pop-A-Plug Tube Plugs eliminate recurring tube leaks while offering the following benefits:

  • Plug material matches tube material preventing thermal expansion and contraction issues and/or undesirable galvanic interaction
  • Unique engineered breakaway controls installation force preventing damage to the tube, tubesheet, and surrounding tubes
  • Maintain helium leak tight-seal to 1 x 10-10 cc/sec
  • Ideal for use in applications with coated tubes and tubesheet

Readily available from large inventory with 24/7 emergency manufacturing capability
