HFT Pipe Freezing Systems
Non-Intrusive Pipe Isolation Technology for Maintenance, Repairs & System Modifications Without Shutdown
Huntingdon Fusion Techniques (HFT) Pipe Freezing Systems provide a safe and cost-effective method for temporarily isolating liquids within pipelines without draining the system or interrupting operations. By creating a controlled in-line ice plug inside the pipe, these systems allow maintenance teams to perform repairs, valve replacements, modifications, and system upgrades while minimizing downtime and product loss. HFT offers two proven solutions: the Accu-Freezeâ„¢ Liquid Nitrogen System and the Qwik-Freezerâ„¢ COâ‚‚ System.
The technology is widely used across oil & gas, petrochemical, food processing, pharmaceutical, water treatment, power generation, marine, and industrial facilities where system shutdowns can be costly and disruptive.
