Abstract

PURPOSE:To prevent the cryogenic effect (strong heat-sink effect) of an underground tank from reaching the surrounding structures, by installing pipes in the ground between the tank and the structures, placing the junction of a heater wire and lead wires in each pipe, and filling the pipe with a liquid of good thermal conductivity.
