Pipe freeze is a method used to freeze the section of a pipe using cryogenic freezing agent that temporarily stops the pipe flow to carry out alterations in the pipeline at the downstream area without having to drain out the entire pipe content. This technique has been used on pipelines containing water based medium for various industries including buildings and process plants.


  1. Cryogenic freezing on pipe act as a temporary plug to stop the flow in a pipeline
  2. Convenient - Do not require drainage of medium in pipe
  3. Do not require system shutdown
  4. Reduction in system downtime
  5. Reduction in time and resources for modification require on the system
  6. No damage to disruption to pipe

  2. Pipe diameter: Up to 48”
  3. Pipe medium: Suitable for various water based medium
  4. Maximum operating pressure: 5,000 psi
