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.

[ We claim:] [1.] A non pressurized method for detecting the presence of potential leak paths across an internal separator located in a generally straight tubular structure, comprising the steps of:orienting said tubular structure in a substantially vertical orientation with both sides of said separator exposed to ambient air at ambient pressure;placing a test gas detector on a first side of said separator;injecting a test gas on the other side of said separator whose density relative to ambient air will cause it to displace the ambient air and move toward said separator; anddetecting whether said test gas appears on the first side of said separator.
