摘要： PROBLEM TO BE SOLVED: To facilitate the carry-in/carry-out and fixing of an inspection device of a low temperature tank for LNG, etc., and to carry out the internal inspection during the service by arbitrarily and remotely scanning the inspection device. SOLUTION: In an inspection device, a longitudinal arm 12, a transverse arm 13, an upright arm 14, and a manipulator arm 15 are arranged in a straight shape by operating articulate parts 16 to enable carry-out/carry-in of the inspection device from a nozzle part of a relatively narrow tank 21, positioning of an inspection probe 18 is facilitated, and the follow-scanning of the inspection pattern from the fixed position of a device body 19 is surely performed. Carry-in/carry-out and fixing of the all-articulation type inspection device 11 for a low temperature tank for LNG, etc., is facilitated, and the all-articulation type inspection device 11 remotely and arbitrarily performs the scanning to enable the internal inspection during the service.

摘要： PROBLEM TO BE SOLVED: To obtain an observation apparatus by which a camera is suspended down to the bottom part of a storage tank so as to observe the inside of a liquid by a method wherein a transparent window part and a directional illumination lamp are installed at the trunk part of a circling device which is suspended inside the storage tank. SOLUTION: An ITV-camera heat insulating box 12 is attached, so as to be tiltable to the up-and-down direction, to the lower end part of a circling device 11 which is suspended inside flammbalegas storage tanks 1 to 3. A transparent window part 18 is formed in a part which agrees with the observation direction of an ITV camera 31 at the trunk part of the circling device 11 which is circled in the horizontal direction, and directional illumination lamps 21 which illuminate only the observation direction are installed inside the window part. The illumination lamps 21 are tilted to the up-and-down direction by tilting mechanisms 24 to 30 in synchronization with the heat insulating box 12. Thereby, since the inside of the storage tanks 1 to 3 can be always illuminated and observed as a whole, it is not required to insert a camera and an illumination device separately, and the inside of a liquid can be observed even in the storage tanks 1 to 3 which have only one nozzle (an opening part). In addition, since it is not required to illuminate all directrons, it is not required to install the transparent window part 18 on the whole circumference, an observation apparatus is resistant to a moment when it is tilted.

摘要： PROBLEM TO BE SOLVED: To surely and rapidly detect a through defect in a membrane. SOLUTION: This testing method for ammonia leakage is carried out on a membrane tank 10 having a tank 2 isolated from a cold-insulation layer 3 by the membrane 4, and comprises the filling of the layer 3 with a pressurized gas, the measuring of displacement 25 of the membrane 4, and the controlling of the filling amount of gas based on the displacement 25. By filling the insulation layer 3 with the pressurized gas, the amount of gas per filling is large, and no air comes into the layer 3 even if there is a defect connecting the layer 3 to the exterior. The determination of the filling amount of gas by the displacement 25 of the membrane 6 means that the pressure in the layer 3 or the flow of the gas can be more closely controlled and the membrane 6 is prevented from being destructed.

摘要： PROBLEM TO BE SOLVED: To reduce the number of steps of work without decreasing a cooling capability and improve a reliability in operation. SOLUTION: A corrugated plate member 21 formed with three ridges 22 is connected to the outer circumference of a tank main body 12 to form a passage (a jacket section) 16 for use in flowing cooling medium through the ridges 22, a welding section 24 against the ridges 22 is reduced, the number of connecting steps is reduced. In addition, even if a certain defect is produced at the welding section 24, leakage of cooling medium to a surrounding area is eliminated and the number of working steps is reduced without reducing a cooling capability so as to improve its reliability in operation.

摘要： PROBLEM TO BE SOLVED: To prevent the damage of a handrail in a dome roof such as a storage tank in which a corridor is arranged around its periphery, by inclining a corridor tread to be lowered toward the outside, fixing a handrail of the corridor in an upright position when the corridor is used, and moving it in a position except for the upright position at the time of a snowfall. SOLUTION: A corridor tread 6 is attached between the periphery of a dome 2 and a peripheral beam 8 while being inclined so as to be lowered toward the outside. The corridor tread 6 is appropriately set at an inclination angle of 6 to 10 deg.. When a corridor is used, a handrail 7 is attachably/detachably inserted in an attaching metal fitting 11, and fixed in an upright position against the corridor tread 6. Also, at the time of a snowfall, the handrail 7 is removed from the female screw sleeve 10 of the attaching metal fitting 11. Under this condition, snow lain on the dome 2 slide on the corridor tread 6 without being disturbed by the handrail 7, and falls from the outer side of a storage tank side plate 1 to the lower part.

摘要： PURPOSE:To provide a membrane fixing structure for a low temperature tank, which is highly economical, in which a plurality of anchors are arranged in a flat plate part of the membrane, each anchor allowing the flat plate part to turn and deform so that flat plate part has a large size while the processing volume of pleats can be decreased. CONSTITUTION:A membrane fixing structure is composed of a body side spherical socket 1 fixed to the inner surface of a concrete body 01 through the intermediary of a relatively large diameter attaching panel 3, a membrane side spherical socket 4 fixed through the intermediary of a relatively large diameter attaching panel 5 which are fillet-welded coaxially to a welding hole 05 in a membrane 03, and a plurality of loosely fitted rod-like anchors 8 each including opposite end spherical protrusions 7 which are loosely fitted in the sockets 1 and 4, and a connecting rod 6 having a center rod part piercing through the sockets 1, 4.

摘要： PURPOSE:To prevent an outer tank from being cooled beyond the service lower limit temperature, by reducing the thickness of a packaging body made up of packing a laminated layer of fibriform heat insulating materials having non-air permeable surface material with an airtight bag upon decompression and then inserting the said packaging body into the inside of an inner tank nozzle expansion joint. CONSTITUTION:A glass wool heat insulating material 14 is provided with a surface material 15 composed of a film having non-air permeability and packaged with an airtight bag 16 constituted of vinyl or the like. And, a packaging body is precompressed whereby the thickness of a laminated body of the glass wool heat insulating material 14, and under this condition, the packaging body is inserted into the inside of an inner tank expansion joint 13. Next, the atmosphere is led into the bag for expansion whereby the laminated body is charged inside the expansion joint 13 without any clearance. Therefore, cold gas is in no case directly touched to the inner tank expansion joint 13 as it convects from an inner tank nozzle 12, thus temperature of an outer tank 11 is prevented from dropping more than the service lower limit temperature.
