A practical method of measuring the heat loss in steam lines using a pitot-static flow meter and throttling calorimeters has been developed as well as a method for locating casing failures in buried pressure-testable steam lines using the inert non-toxic gas sulfur hexafluoride as a leak tracer and an ion capture device as a detector. These methods require no knowledge of thermodynamic, mass transfer, or heat transfer theory. They are simple, quick, and inexpensive, and the equipment used is easily portable. Details sufficient for application by untrained field personnel as well as the results of several field tests are described. Author
