LOW-TEMPERATURE TANK SUCH AS LNG, AND ITS CONSTRUCTING AND INSTALLING METHOD

摘要

PURPOSE: To provide a low-temperature tank having a low thermal stress dispensing with any heat contraction measurement, and having the optional system and shape. ;CONSTITUTION: An inner tank 3 restricted by a plurality of linear or point anchors 2a through a cold insulating material 4 such as pearlite having no internal pressure transmitting function, and made of materials having pressure resistance, airtightness and small coefficient of linear expansion is constituted on the inner wall of an outer tank 1 constituted of concrete, and able to resist the external pressure, and the internal pressure load of the inner tank 3 is transmitted to the outer tank 1 through the anchors 2a.;COPYRIGHT: (C)1996,JPO
