Shutting down the whole system isn’t always the answer. We freeze a section of pipe to form a temporary pressure barrier - full isolation, no depressurization, no permanent modification.
How It Works
We apply liquid nitrogen to the outside of the pipe at a controlled rate, forming a solid ice plug that holds differential pressure while work proceeds downstream. Once the job’s done, the freeze thaws naturally - no trace, no modification.
Deploy Us When
- Upstream isolation is unavailable or unreliable for a valve replacement
- A pipeline needs modifying without a full depressurization or shutdown
- You need temporary isolation to run a pressure test
- A wellhead component needs replacing and existing barriers can’t be verified
- A valve has failed and you need emergency isolation now
When mechanical isolation tools can’t be deployed, or the geometry won’t take a plug, freeze isolation gets the job done - without the cost and downtime of a full shutdown.
