Pipe Freezing Sydney

Pipe freezing is highly regarded as the best technique for preparing pipes containing water for repairs, maintenance and upgrade works. Fluid in the pipes doesn’t have to be drained down anymore, and that’s a huge advantage of this method since it saves a lot of time and allows you to avoid the costly process of refilling and venting.

It is a technique 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 can be carried out on the pipe between the edges of the ice plug. Once a solidly frozen plug is formed, pipework modifications can be undertaken with confidence. 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?

When you have a large, commercial or multi-story living space, it would be impractical to shut off the flow of heating or hot water to the entire building just to have a pipe repair. Pipe freezing will allow you to isolate only parts of installations that need reparation, while unaffected areas of the house or building can still have heating or hot water throughout the repair or alteration.

We will be able to quickly solve isolated drain and pipe faults in any part of Sidney, Central Coast, Hunter, Newcastle, Canberra, and surrounding areas. Our well-trained, experienced technicians will ensure you get only the best pipe freezing service at competitive rates.

Pipe freezing Sydney is the best solution in numerous situations, and listed below are just a few of them:

  • To perform maintenance and repair works on pipes with non-functional valves.
  • When repair works are required on leaking pipes.
  • 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.
