| Abstract: | It has been proved that it is indispensable to control the forming size and weld residual stress of the inner shell in a strict way by analyzing the burst accid ent of the outer shell which was caused by buckling deformation of the inner she ll when the gas pressure test was carried out for the sandwich of a fixed cryoge nic liquid storage vessel.Furthermore it is necessary to strengthen procedure mo nitoring for sandwich gas pressure test and vacuum leak-inspection. |
