Every line needs its own plan.
This overview describes the method. Koppl reviews the line conditions and required work before selecting equipment and procedures.
Discuss your projectThe core principle
Pipe freezing cools the liquid inside a pipe until a controlled ice plug forms. The plug adheres to the pipe wall and creates temporary isolation for downstream modifications or repairs.
The freezing chamber
A chamber is fitted and sealed around the selected pipe location. Liquid nitrogen is introduced into that controlled space. Electronic sensors and visual frost lines help the field crew monitor plug formation.
Managing trapped pressure
Freezing work must account for system geometry and dead ends. Bleed-off points and system monitoring help manage the pressure condition around the forming plug and verify the downstream work zone.
Returning the system
After the planned work is complete, injection hoses, sensors, and the chamber are removed. The plug thaws and the piping returns to its original physical configuration.
What to send Koppl
Share the pipe size, material, wall thickness if known, operating pressure and temperature, media, line location, access, timing, and the work that needs to happen. Include current photographs and drawings.
