Estimated useful life for above ground water mains with heat wrap

  • 1.  Estimated useful life for above ground water mains with heat wrap

    Posted 24-02-2022 04:39
    Hi,

    The Regional District I am working for here in Canada, owns a few water main lines buried above ground from the 70' and 80's. These lines are wrapped in a heat wrap to prevent the main from freezing. With the extended period of cold weather we had in January, I worry the 50to 60 year old heat wraps are not working. Does anyone know what the estimated useful life for watermain heat wrap is?

    Thanks in advance,
    Silje
