Pipe Freezing

Pipe freezing is highly regarded as the best technique for preparing pipes containing water for repairs, maintenance, and upgrade works.

Pipe freezing is a method used to freeze the contents of a section of a pipe by applying liquid nitrogen to the perimeter of the pipe in a controlled manner until the contents of the pipe freeze and form an ice plug. The ice plug adheres to the pipe walls stopping water from flowing through the pipe during pipe repairs/maintenance works.

At this stage of the process (and only at this stage), isolation of a section of the pipe is achieved and work is able to be carried out on the pipe between the edges of the ice plug.

Our technicians remain on site as required by the Plumber/Air Conditioning & Refrigeration Mechanic, usually until all works have been completed.

When is Pipe Freezing needed?

  • To perform maintenance and repair works on pipes with non-functional valves.
  • When repair works are required on leaking pipes.
  • In order to replace valves or flanges in pipes with no zone valves.
  • To allow insertion of a branch in pipes with no zone valves.
  • Only option – For many commercial and industrial applications.
