Pipe Freezing
Pipe freezing is a safe, efficient method used to temporarily isolate a section of pipe without needing to drain the entire system. By creating a solid ice plug inside the pipe, repairs and maintenance can be carried out quickly and cleanly — ideal for situations where shutting down or draining the system isn’t practical.
Our pipe freezing service includes:
- Liquid nitrogen pipe freezing
- Temporary isolation of water lines
- Safe and controlled ice plug creation
- Non-intrusive repairs and maintenance
- Suitable for residential, commercial, and industrial systems
This technique saves time, reduces disruption, and allows critical repairs to be completed with minimal downtime.
