Pipe Freezing Kit

The Pipe Freezing Kit eliminates the need to drain systems and shut down operating equipment when making pipe repairs. The kit uses liquid carbon dioxide to create ice plugs in sections of pipes. Kits are supplied with three freezing jackets for pipes ½"-4" (13-114mm) O.D.

To operate, turn off the pipe flow and attach a freezing jacket to the pipe upstream from the section needed to be repaired. Fill the freezing jacket with CO2 and an ice plug will form. After completing whatever work is needed, remove the jacket and the ice plug will defrost.

Note: the Kit hose fittings may not be compatible with other CO2 cylinders.
The Kit can be used for pipes ½"-4" (13-114mm) O.D. including three freezing jackets, two 8' (2.4m) hi-pressure hoses, T connector, 20 lb (9.1 kg) CO2 cylinder (unfilled), safety glasses, pair of insulated gloves, instructions for use and a carrying bag.

Pipe freeze plugging is a simple, cost-effective method to perform pipe maintenance or line modification without shutting down your plant process. Using liquid carbon dioxide (CO2)you can isolate the problem area in the line with SOLID freeze plugs of the fluid within the line. This allows the job to be done with no drain-down or refill, no loss of expensive process fluids, and no system downtime. Once the work is completed, the plugs are thawed and the line is back in operation. Standard freeze plugs range in size from ½" to 4" (13-114mm) O.D.
