Abstract: A membrane finishing sheet, which is disposed at a membrane finishing part among multiple membrane sheets which form a sealing wall installed at a membrane type cargo, comprises a corrugated part having a structure closed in a direction toward the membrane finishing part. In addition, a membrane insulation structure comprising a membrane finishing sheet according to the present invention comprises a membrane finishing sheet disposed at a membrane finishing part among multiple membrane sheets which form a sealing wall installed at a membrane type cargo. Among four sides of the membrane finishing sheet, a finishing side in contact with the membrane finishing part has a structure in which the corrugated part is closed and thus provides a membrane insulation structure that does not require a separate finishing member for sealing a membrane.

Abstract: The cartridge includes a body containing the air and a head closing the body. There is a filling channel, which connects the outside of the cartridge to the body and which includes a filling non-return valve preventing the air from exiting the body. The head includes an inflation channel, which connects the filling channel to the body and includes an inflation non-return valve preventing the air from exiting the body. An inflation organ is movably mounted on the inflation channel to permit opening of the inflation non-return valve.

Abstract: The invention concerns a sealed tank including adjacent first and second walls each comprising a corrugated sealing membrane. The sealing membranes of the first and second walls join at the level of an edge, wherein the sealing membrane of the first wall includes a first series of corrugations and a second series of corrugations intersecting at the edge, and the sealing membrane of the second wall includes a third series of corrugations intersecting at the edge. The tank further includes a corner arrangement comprising a sealing membrane that is welded in sealed manner to the sealing membrane of the first wall and to the sealing membrane of the second wall, such that the corrugations of the first series of corrugations are connected to corrugations of the third series of corrugations and the corrugations of the second series of corrugations are connected to the corrugations of the third series of corrugations.

Abstract: A workpiece includes a plurality of knots and webs, which are formed in one piece, of a sheet metal, in particular a steel plate. Each web extends between two openings from one knot to another knot, and at least three webs meet at each knot. A plurality of the webs has a cross section, which includes at least one hardened and one unhardened area.

Abstract: A fixing device of a first barrier-reinforcing member for supporting first and second corrugated portions that are formed in a first barrier to cross each other in a liquefied natural gas (LNG) storage tank including a heat-insulating board and a first barrier positioned thereon and forming an inner wall, includes: a fixing bracket including a coupling portion fixedly inserted in insertion grooves formed under lateral sides of a crossing portion where the first and second corrugated portions cross, and a body coupled to one side of the coupling portion; and a first fastening member for fastening an impact-absorbing plate between the heat-insulating board and the first barrier with the other side of the body. The reinforcing member is fixed to inner sides of the first and second corrugated portions by the impact-absorbing plate.

Abstract: The present invention is related to a reinforcing member for a membrane for improving the pressure-withstanding property of the membrane having corrugations, and a membrane assembly having the reinforcing member and a method of constructing the membrane assembly. By providing a reinforcing member for a membrane having corrugations and installed in an insulating structural member of an LNG cargo, the present invention can prevent the collapse of the corrugation and attenuate shocks against a same load without increasing the facial rigidity of the corrugation, and improve the insulating property by forming an additional insulating layer.

Abstract: A hydrogen storage tank for a hydrogen fueled aircraft. The tank has a wall made of layers of aerogel sections around a hard shell layer, sealed within a flexible outer layer, and having the air removed to form a vacuum. The periphery of each layer section abuts other sections of that layer, but only overlies the periphery of the sections of other layers at individual points. The wall is characterized by a thermal conductivity that is lower near its gravitational top than its gravitational bottom. The tank has two exit passageways, one being direct, and the other passing through a vapor shield that extends through the wall between two layers of aerogel. A control system controls the relative flow through the two passages to regulate the boil-off rate of the tank.

Abstract: A hollow cylindrical vessel comprising a cylindrical outer shell (12) and a cylindrical inner shell (14) joined by annular end caps (16), wherein at least one of: an end cap, or the cylindrical outer shell (12), or the cylindrical inner shell (14), is provided with an arrangement of recesses or protrusions (18). Preferably, the arrangement of recesses or protrusions is asymmetrical in all axes.

Abstract: A barrier layer arrangement for tank systems includes at least one layer made of a material that has anisotropic properties. The anisotropic properties can be specifically adjusted by way of the design of the layer and/or the material parameters.

Abstract: Disclosed is a vessel including an outer shell and an inner shell, the inner shell having spaced apart concave recesses formed therein to facilitate a thermal expansion and contraction of the inner shell to militate against failure thereof.

Abstract: Disclosed is a liquid container adapted to store liquefied natural gas (LNG). The LNG storage container include a sealing wall directly contacting liquid contained in the tank and a structural wall, which is an exterior wall or inner structure integrated with the exterior wall. The container further includes a plurality of connectors mechanically connecting the sealing wall and the structural wall and an intermediate wall structure positioned between the structural wall and the interior wall. The intermediate wall structure is configured to move relative to at least one of the interior wall and the structural wall.

Abstract: A liquefiable gas pressure cylinder and method for making the same with the cylinder including a cylindrical shell, and heads fusion welded at opposites ends of the shell. The side ends where the heads are joined to the shell are crimped radially inward to each end to form chimes. The welds are 100% radiographed and heat treated. The heads are dished to have a domed center portion which has a profile and thickness so that the domed center portions will reverse before any other part of the cylinder is stressed beyond a yield limit for such part.
