This short video clip shows a Liquid Nitrogen Cryoshell (Freeze Jacket), for making two ice plugs in a pipeline full of contaminated water. The ice plugs allowed a centre piece to be removed for access purposes, while the two ends in the pipeline could be safely capped off by welding on a metal blanking piece. With this fix, only the contaminated water in a short length of pipe, needed to be disposed of instead of the enormous volume in the whole pipe. The Freeze was made with an Accu-Freeze™ Pipe Freezing System which is available from Huntingdon Fusion Techniques HFT®. A full project description is available on request.
