A new system allows real-time remote temperature monitoring along the length of a pipeline during hydrotesting. The system 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 lared internal corrosion, external damage, or any other factor potentially reducing WT would also likely require hydrotesting in the current environment. This article illustrates both the economic and data-quality aspects of remote digital temperature gathering during hydrotesting.
