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. Liquid nitrogen flow rates, controlled by the temperature controllers, are based on the requirements of the freeze process to maintain a desired level of superheat. The freeze operation is divided into distinct phases each with a different nitrogen superheated exhaust temperature. At the end of the repair, electric heaters wrapped over the pipe proceed to thaw the frozen oil. The heater controller thaws the frozen plugs based on an embedded time versus temperature protocol. The freeze prevention heaters are wrapped over the freeze jackets to prevent ice formation over the cold freeze jackets while the freeze plug is formed and maintained. This technology results in less thaw and freeze time at reduced liquid nitrogen usage.
