Pipe freezing is a method of isolating the interior space of a pipe in order to repair or maintain it. This clever, technologically advanced solution offers a way around a complete shutdown of the system, which is the expensive, time-consuming, and inconvenient alternative. Instead, the liquid contents of a short section of pipe are frozen using carbon dioxide or liquid nitrogen in order to form a plug of ice, effectively blocking off the relevant part of the pipe that needs work.
Duncan’s Plumbing offers Canberra’s foremost pipe freezing service, with the ability to freeze most metal pipe systems of between 6–40mm in diameter. Our method of controlled pipe freezing can be used for piping modifications, valve replacements, hydrostatic testing and system maintenance.
Upon completion of the maintenance or repairs, the ‘ice plug’ can simply be left to melt naturally, allowing the system to flow once more. Call our friendly service team to find out more or book an appointment today.
