Method of testing for leaks in a contained system |
| 摘要 |
A method of testing for leaks in a contained system with an interior containing system gas and system liquid at an operating pressure, the method comprising: pressurizing the interior of the contained system, by introduction of gas comprising tracer gas into the interior, to at least 0.5 pounds per square inch above the operating pressure to disperse the tracer gas throughout the system liquid; and sensing for the presence of the tracer gas using one or more sensors located outside the contained system. |

1. A method of testing for leaks in a contained system, the method comprising:
pressurizing an interior of the contained system, wherein the interior contains system gas and system liquid at an operating pressure, the system liquid and the interior defining a headspace of system gas above the system liquid, wherein pressurizing the interior includes introducing gas comprising tracer gas directly into the headspace, in which the tracer gas is soluble in the system liquid, to at least 0.5 pounds per square inch above the operating pressure to disperse the tracer gas throughout the system liquid; and sensing for the presence of the tracer gas using one or more sensors located outside the contained system to detect tracer gas that has escaped the contained system and traveled from the contained system to the one or more sensors. |
