Freeze sealing pipes for repair or maintenance is an increasingly popular alternative to ‘hot-tapping’ and eliminates the need to shut or drain down a system for repairs and maintenance. These systems work by creating ice plugs (or ‘freeze seals’) upstream of the repair site or on either side of an area where a pipe system needs to be maintained.
The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® provides Qwik-Freezer™, the industry standard portable CO2 Pipe Freezing System. With thousands of kits in use around the world, Qwik-Freezer™ covers pipe diameters from 3/8” – 8” (9 – 200 mm).
Qwik-Freezer™ is quick and easy to use, requires little set-up time and is the only CO2 Pipe Freezing System capable of freezing up to 8” pipe. Even for smaller diameter freezes, Qwik-Freezer™ produces ice plugs that are significantly more reliable and robust, capable of withstanding far more pressure than the smaller plugs that other types of systems will produce.
