Pipe Freezing

Pipe Freezing quickly and safely causes pipeline flow isolation, using liquid nitrogen to temporarily freeze fluid in existing pipes.

Flow, in virtually any size pipe, is thereby controlled to completely shut-off  pipe fluid content movement, whilst works are carried-out to rectify a maintenance issue (such as to fix a leak or repair a section of pipe), and/or to cost-effectively cease flow in an area where changes to your pipework system need to be made. The solid freezing of the pipe’s contents causes a plug effect. It allows for minimised disruption to the site’s operation, it can usually be carried out without shutting anything down, and there is no potential for environmental damage or waste disbursement due to the process’s effectiveness in keeping any chemicals, water or other fluids contained.

The solid nature of the freeze plug means that isolated pipe plumbing works for HVAC systems, water systems, condensers and water mains can be repaired, altered, or have maintenance procedures carried-out, in all types of buildings and facilities in a short time frame, without having to shut-down any unrelated pipes or building operations. The length of time a plug needs to be in place can be tailored to suit the situation, and high pressure can be applied without dislodging the frozen sector of pipe. This allows for your other contractors to do what they need to do, with the assurance that the temporary freeze plug remains securely in place.
