Pipe Freezing Explained: What is Pipe Freezing?
What is pipe freezing is a common question. It’s a method you can use to modify and restore pipework. Pipe freezing is a non-invasive, regulated method, using liquid nitrogen to isolate pipework, allowing you to carry out pipework modifications.

To help explain ‘What is Pipe Freezing’ in more detail…
We’ve asked Paul Neve, IDWe Ltd’s Pipe Freezing Expert.

Does pipe freezing work?
Yes!
How does pipe freezing work?
Firstly, you fit a pipe freezing jacket, apply liquid nitrogen onto the external surface of the pipe where the jacket is sitting. The nitrogen then cools the exterior of the pipe enough for the liquid to solidify. The frozen fluid isolates a section of the pipe so that repairs or modifications can be carried out.

It is around -196 Degree Celsius.
