PURPOSE: A LNG(Liquefied Natural Gas) storage tank is provided to utilize advantage of a storage tank which is composed of an inner shell, an insulation layer part, and an outer shell because the exterior of the storage tank can connect with a valve. CONSTITUTION: A LNG gas storage tank comprises an inner shell(110), an outer shell(120), an insulation layer part(130), and a connecting part(140). The inner shell is composed of a metal which can endure in low temperature of the LNG and stores the LNG. The outer shell surrounds the exterior of the inner shell. The insulation layer part is installed in a space between the inner shell and the outer shell and reduces heat transfer. The connecting part comprises a first flange and a second flange. The first flange is formed in end of an inlet extended outward from the inner shell. The second flange is formed in one end of an extended part which is extended to surround the inlet from the outer shell. |
