The pipe is used in district central heating. The equipment to be used: Thermocamera Agema 570 from Flir. Is there any literature on the subject?                  Reply  Translate  Close   Kåre Johansson Kåre Johansson 08:12 Nov-05-2002 Re: Infrared Thermography of buried pipes : Is it possible to detect bad insulation or leakage from a buried hot water pipe located about 1m underground? : The pipe is used in district central heating. : The equipment to be used: Thermocamera Agema 570 from Flir. : Is there any literature on the subject? . We have detected "thermal leakage" using an Ageema 550. Unfortunately it is difficult to say if such thermal leakage is due to insultation failure or leaking hot water. Only digging in the affected areas will tell you. In our case it was the sand and backfill which had settled. Perhaps experience will show the difference between leaks and settlement. I don't know of any literature, but I am sure there is some - somewhere.

Perhaps a little bit less effort than digging.                  Reply  Translate  Close   Product Spotlight MUSE Mobile Ultrasonic Equipment StandHillger Ing.
