PIPE FREEZING SERVICES

PIPELINE FREEZE PLUGS

Pipe freezing is a method which freezes the content of a section of a pipe by applying the cryogenic freezing agent in a controlled parameter. Once the targeted area is thoroughly frozen, termination or modification can be carried out without having to drain out the entire pipe content.

This technique has been used on pipelines of various industries and buildings, process plants and pipelines containing water based mediums.
