The present invention relates to a cryogenic storage tank. A cryogenic storage tank according to the present invention fills a first insulator between an inner container and an outer container in order to remedy infiltration of heat through a pipe line exposed from inside to outside and double-insulates by filling a second insulator in the pipe line, thereby minimizing the creation of evaporative gas by remedying heat infiltration from outside through controlling gas flow and decreasing the infiltrated amount. Accordingly, the pressure of a cryogenic storage tank can be easily prevented from increasing so that the storing and transporting efficiency of liquefied natural gas can be improved. |
