Nuclear Plant Journal, July-August 2018 NuclearPlantJournal.com 7 Your success is determined by consistently providing energy to your customers, and providing that energy depends on safe and event-free operations. Unreliable condenser tube plugging solutions such as elastomer or friction fit plugs can degrade and/or eject over time, leading to cooling water in-leakage (and other issues) that can cause equipment failure. Don’t let an unreliable tube plugging method cut your next “breaker-to-breaker” run short! The Pop-A-Plug ® Tube Plugging System from Curtiss-Wright EST Group offers a perfect solution to plants looking for an engineered solution to seal leaking and degraded heat exchanger and condenser tubes. Since 1981, Pop-A-Plug Tube Plugs have been performing reliably under severe operating conditions, providing the lowest life-cycle cost as compared to alternative plugging methods. Pop-A- Plug Tube Plugs are rated for service up to 7,000 PsiG (483 BarG) and 1100 o F (593 o C); Pop-A-Plug Tube Plugs conform to ASME PCC-2-2015 (Article 3.12) recommended mechanical tube plugging repair methods and meet all guidelines in the EPRI Condenser In-Leakage Report. Simple and quick installation coupled with reliable performance over the life of a heat exchanger are imperative design goals for any tube plugging system. Pop-A-Plug Tube Plugs achieve these objectives by: 1) creating a simple metal- to-metal seal providing long term reliability versus expandable rubber plugs; 2) fast installation - eliminating welding, pre-heat & PWHT; 3) eliminating tube end and tube joint damage caused by hammer-in tapers and seal welded plugs; and 4) provide a helium leak tight seal to 1x10 -10 cc/sec. Pop-A-Plug Tube Plugs can easily handle pressure upsets occurring during nuclear power plant LOOP or SBO events. Pop-A- Plug Tube Plugs can be supplied under ISO- 9001:2015, 10 CFR 50 Appx B, or ASME Section III Quality programs. Documentation packages include: Certificate of Conformance, Certified Mill Test Reports (CMTR), Independent Test Results of Raw Stock, and Production Lot Pressure Test Reports. Curtiss-Wright EST Group maintains a large inventory, with 24/7 emergency manufacturing capabilities. Ask about our Heat Exchanger Assessment Tool (HEAT) and Outage Job Box Programs.
