A new system allows real-time remote temperature monitoring along the length of a pipeline during hydrotesting. The system (Fig. 1) uses a radio temperature transmitter connected with a thermocouple installed underground on the surface of the pipeline, communicating the pipe’s temperature directly to a remote database that saves all data transmitted.As new pipelines are built and proper facility maintenance requires increasing scrutiny of the integrity of pipelines long in service, the need for hydrotesting will only grow, placing an increasing premium on performing hydrotests as efficiently as possible. Unexpectedly large internal corrosion, external damage, or any other factor pot...
