<p>PURPOSE: To allow re-disassembly even after the completion of the assembly by providing the components between an inner tank and a jacket with removable covers and making the jacket sub-dividable to the shorter section and longer section of the jacket and assembling the jacket with minium welding work. CONSTITUTION: The components 3, 7 disposed between the inner tank 1 and the jacket 11 have the removable covers 5, 9 at the ends on the side where a first pipe 15 exists. In addition, the components are provided with recesses 31, 71 extending to the ends thereof so that the pipe 15 may be introduced from the ends of the components when the covers are removed. A second pipe 16 is disposed near the recesses of the outer tank 7 and the jacket 11 is sub-divided to the longer section 20 and shorter section 45 of the jacket along the plane neighboring the pipes 15, 16 and existing on the side of the pipe opposite to the jacket 11 end. The peripheral surface of the shorter section 45 has an opening 53 for the pipes 15, 16 penetrating the jacket 11 and a tower 19 enclosing the pipes 15, 16 is coupled to the jacket 11 along this opening 53.</p> |
