Abstract: A freeze and thaw system using knowledge-based hardware and methodology is provided for repair of oil-filled pipes. Liquid nitrogen is boiled off inside freeze jackets installed over the pipe, exiting in a superheated vapor state.

This technology results in less thaw and freeze time at reduced liquid nitrogen usage.
