  • Non pressurized method for heat exchanger internal leak detection
    Patent number: 5835976
    Abstract: A non pressurized internal separator leak test method is disclosed for a two pass condenser in which helium is injected below a vertical manifold tank separator, allowed to rise, and detected or not detected above the separator. The helium cannot reach the upper side of the separator other than through a separator leak path, because it will not flow sideways down the flow tubes.
