Abstract: In the construction of largescale cryogenic storage tanks, the air lifting operation of tank roof is the difficulty and key point in construction and safety management. Aiming at the previous problems of complex construction schemes, much materials used for improvement measures, and long construction preparation period, some improvements are made to the tank roof air lifting technology combining with years of practice, especially the balancing system and sealing system have been optimized. And good application effects have been achieved.

Key words: large-scale cryogenic storage tank, tank roof air lifting, new technology, balancing system, sealing system, optimization
