摘要： PURPOSE:To detect the gas leak from an inner tank at an early stage and to detect the leaking point, by partitioning at least one part of the outer surface of the inner tank, and providing a gas-leak-detecting sampling means for every cell covered by a film. CONSTITUTION:Cells are formed in the roof part and the side plate part of an inner tank 1. A film 2 is provided in each cell so as to cover the cell wall. The outside of the film is contacted with the outer surface of the inner tank 1. A gas-leak-detecting sampling device 3 is provided between the outer surface of the inner tank and the film 2 in each cell. The part between the film 2 and an outer tank 4 is filled with pearlite 5. Nitrogen gas between the outer surface of the inner tank and the film 2 in each cell is sucked to a gas-leak detecting instrumentation by a pump, which is connected to the gas sampling device 3. Nitrogen gas is introduced into the space from a nitrogen feeding pipe and made to of flow through the space. When stored low-temperature liquid gas leaks from the inner tank, the gas is mixed into the flowing nitrogen gas. The gas is sampled and detected by the gas-leak detecting instrumentation.

摘要： PURPOSE:To form a complete seal against volatile gas stored in an upper part of a tank by press-supplying inert gas into scattered microscopic gaps formed despite an attempt to bring a seal plate and a hatch cover plate into a metal- to-metal-touching state. CONSTITUTION:N2 gas is press-supplied from an inert gas supplying pipe 24 at the flow rate of about 200cc/sec and at the pressure of 2,000mm.H2O that is higher than that of volatile gas, 300mm. to 1,500mm. H2O, stored in an upper part of a tank 1, and it is branched after passing an inert gas supplying pipe 23 and press- supplied into a recessed groove 21. Thus through scattered microscopic gaps between a seal plate 3 and a hatch cover 11, the N2 gas is press-supplied to an upper part of the tank 1 and to the inside of a maintenance nozzle 2. Accordingly, owing to the N2 gas pressure as well as a metal-to-metal-touching state, the volatile gas stored in the upper space of the tank does not leak into the maintenance nozzle 2, being kept in a complete seal.

摘要： PURPOSE: To make the radiation penetration of the curved parts of a shape material uniform and facilitate the inspection of weld zones by disposing jigs which fit to the curved parts in the welding place of the shape material having the irregular thickness curved surfaces between the side plate of the lowermost stage and the bottom plate.
CONSTITUTION: A jig 7 provided with a curved surface 5a conforming to one irregular thickness curved surface 4a of a shape material 1 and having a surface 6 of which the top surface is parallel to the bottom surface of the material 1 is fitted to said material. A film 8 is abutted on the bottom surface of the material 1 and the radiographic inspection in an arrow direction is carried out. The radiographic inspection is also carried out in the similar manner by using a jig 9 having a curved surface 5b conforming to the other irregular thickness curved surface 4b. Thence, the radiographic inspection is carried out by using jigs 12, 13 provided with curved surfaces 5c, 5d conforming to the remaining parts of the curved surfaces 4a, 4b an having surfaces 10, 11 of which the respective end faces are parallel with the vertical faces of the material 1 and abutting a film 14 on the surface 10 of the jig 12. Thereby, the radiation penetration of the curved surfaces of the mutual welding zones of the shape material 1 are made uniform.
