Line Freezing Services

What is Line Freezing?

This innovative service method isolates a section of pipe by freezing the liquidpipe contents so that it forms an ice plug. The adhesion of the ice to metal allows this plug to hold back the product to allow modifications to make to the system.

A freezing container is installed and sealed on the pipeline with a special tape, enabling it to contain liquid nitrogen that is injected in order for the pipeline to be frozen and monitored. Once an ice plug is formed, the essential repairs or updates can be made.
