  • Hydrotesting on Slopes: The Hills Have PSI!

    Hydrotesting on Slopes: The Hills Have PSI!

    By Ken Rickvalsky, ENV SP, NACE CT   10/28/2021  In Installation Technical

    Dear Ditch Doctor: Out here in the western United States, we wind up with a lot of pipelines installed up or down serious hills, dare I say mountains as well? We are good at the construction part, yet time after time we struggle with getting a satisfactory post-installation hydrostatic test on the pipeline, especially with inclined installations. Often the pipeline drops anywhere from 20 to 50 psi on the gauge and can do that several times or more until we take some sort of drastic redo/restart on the test procedures.

He wants us to dig up the 1,000 feet of pipe we've already installed and reverse each pipe. Is he for real? Does it really matter?
