PIPE FREEZING PROCESS
Liquid Nitrogen is used to form a freeze plug within the pipe in order to allow work to be carried out on the system, without the need for a drain down. Pipe freezing using cryogenic liquids such as Nitrogen is industry proven and has been in use for more than 30 years.
A totally inert gas, Nitrogen makes up almost 80% of the air we breathe. Using correct handling procedures Liquid Nitrogen is perfectly safe and simple to use. Pipe freezing with Liquid Nitrogen enables large diameter pipes carrying various fluids to be frozen in a very timely and cost efficient manner.
Nitro Pipe Freeze creates a dam around the pipe into which the Liquid Nitrogen is poured. Once a plug has formed it is capable of withholding pressures in excess of 4000psi and this is maintained to allow pipework modifications to be undertaken with confidence.
