[0002] A large tank gas storage facility is a facility used to store natural gas, and its high side wall sealing layer is a key component to ensure the safe and efficient operation of the gas storage facility. The main function of the high side wall sealing layer is to prevent gas leakage, maintain the pressure inside the gas storage facility stable, and protect the gas storage facility from the external environment.
