Pipe Freezing
Pipe Freezing (Cryogenic) is an advanced technique for temporary pipe isolation, offering the safest, most cost-effective and efficient method for valve replacement and general pipework modifications. This process eliminates the need to drain the system, significantly saving time and avoiding the complex and expensive process of refilling and venting. Toxic fluids, which would otherwise need to be drained, stored or disposed of, can remain in place, preventing potential hazards and additional costs.
Pipe freezing works by lowering the temperature of the fluid within the pipeline to create an ice plug, effectively isolating the section of pipe that requires work. This technique can be applied to a wide range of pipeline materials, including carbon steels, aluminum alloys, cast iron, stainless steels, epoxy-coated pipes, nickel alloys and copper base alloys. The pipeline fluids that can be crystallized into an ice plug include fresh water, glycol solutions, sea water, effluents/sewage, produced water and more.Overall, pipe freezing offers a reliable solution for safely carrying out maintenance and modifications without the need for system shutdowns, making it an ideal choice for industries requiring minimal disruption to operations.
