|Comment||Hi Fred, thanks for the input .. your advice is solid and very logical. I've heard from several about the " brittleness " caused by the freezing and we have decided to use a Sharkbite fitting instead. I sincerely appreciate your prompt response .. thanks ! Jug|
Controlled pipe freezing: I can answer questions about how pipe freezing with liquid nitrogen can help you isolate a section of pipe for repairs under full system pressure without the need to shut down or have to drain the system. Water, oil, chemicals can be frozen safely to allow your maint. department to do the needed repairs.Freezing can be done on steel, copper, cast, PVC pipe, etc. I have frozen pipes at 1500 lbs pressure and up to 24" in Dia.
