Tubesheet Mapping This service provides an at-a-glance summary of heat exchanger condition. Upon completion of a comprehensive non-destructive testing evaluation Conco can create a multicolor tubesheet map for graphic illustration of tube wall condition. The overall condition of the condenser or heat exchanger and any developing trends are obvious as each tubes condition is represented by a different color or symbol. 1-800-569-5523 I 15 Tracer Gas Leak Detection While air in-leakage negatively impacts plant performance tube leaks can cause forced shut downs costing plants thousands in maintenance lost productivity and contaminated product. Using advanced tracer gas leak detection technology Conco technicians can quickly locate sources of leaks. Conco has been an innovator and leading provider of leak detection services for over 30 years and offers both helium and SF6 tracer gas technology. Conco crews can detect n Condenser air in-leakage n Condenser tube leakage n Sources of dissolved oxygen n Stator water system leakage n Main generator leakage Depending on leak characteristics a determination is made whether to mobilize with the helium mass spectrometer system the state-of-the-art Conco Fluorotracer system or both.
