MOUNT FOR DOUBLE-WALLED VESSEL, VESSEL COMPRISING A MOUNT AND VEHICLE COMPRISING A VESSEL
A mount for a double-walled vessel includes a first support to support the mount against an outer wall of the double-walled vessel, a second support to support the mount against an inner wall of the double-walled vessel, and a flexible member connecting the first support and the second support. The first support and can be arranged at a first end of the flexible member and the second support can be arranged at a second end of the flexible member opposite to the first end. Further described are a vessel including at least one such mount as well as a vehicle including such vessel.
Vacuum insulated articles with reflective material enhancement
Provided are vacuum-insulated articles that comprise an evacuated space disposed between first and second walls and a reflective material disposed within the evacuated space. Also provided are methods of fabricating such articles.
Device and method for determining the thermal insulation quality of twin-walled, vacuum-insulated containers
A dual-wall, vacuum-insulated container (30, 40) has an external wall (1), an internal wall (3) and there in-between a vacuum chamber (5), in which there is arranged a heat insulation device (2, 20). At least three temperature sensors (13, 13a, 13b, 14, 15) that are spaced apart from another recurringly register instantaneous temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) of the container (30, 40). At least in some points there is calculated a temperature course using a heat insulation model on the basis of the construction and material characteristics of the container and the heat radiation resulting therefrom, which temperature course contains at least two of the temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) registered. From the temperature course there is calculated a desired temperature value for the position of at least one further of the temperature sensors and compared with the actual temperature value actually registered by this temperature sensor. From the deviation between the desired temperature value and the actual temperature value there is detected a change of the heat insulation quality of the container.
TANK HAVING ENHANCED INSULATION COMBINING THERMAL INSULATION MATS WITH MICROSPHERES, AND METHOD OF MANUFACTURING SUCH A TANK
A tank suitable for storing a product at a cryogenic temperature, including a fluid tight interior barrier, a fluid tight exterior barrier, surrounding the first interior barrier, an intermediary volume interposed between the interior and exterior barriers and at least one insulating layer positioned in the intermediary volume and including at least one thermal insulation mat, with very low thermal conductivity. The intermediary volume contains microspheres outside of the thermal insulation mats and has an enhanced level of vacuum. This solution makes it possible to maintain satisfactory performance in terms of thermal insulation even in the event of a loss of vacuum in the intermediary volume.
Pressure Vessel and Motor Vehicle
A pressure vessel, in particular a cryogenic pressure vessel, has an inner vessel, an outer vessel and a chamber that can be evacuated at least partly. A motor vehicle includes such a pressure vessel.
MOBILE CRYOGENIC TANK AND PROVISIONING METHOD
Mobile cryogenic tank for transporting cryogenic fluid, notably liquefied hydrogen or helium, comprising an internal shell intended to contain the cryogenic fluid, an external shell arranged around the internal shell and delimiting a space between the two shells, said space containing a thermal insulator, the first shell having a cylindrical overall shape extending along a central longitudinal axis (A), when the tank is in the configuration for transport and use, the central longitudinal axis (A) being oriented horizontally, the tank comprising a set of temperature sensors measuring the temperature of the fluid in the internal shell, characterized in that the set of temperature sensors is situated on the external face of the internal shell and measure the temperature of said shell, the set of temperature sensors comprising a lower sensor positioned at the lower end of the internal shell situated below the central longitudinal axis (A), the set of temperature sensors further comprising a plurality of intermediate sensors distributed over two lateral faces of the internal shell on each side of the central longitudinal axis (A), the plurality of intermediate sensors being distributed vertically between the lower end of the internal shell situated below the central longitudinal axis (A) and the upper end of the internal shell situated above the central longitudinal axis (A).
METHOD FOR MANUFACTURING A WALL OF A SEALED AND THERMALLY INSULATING TANK HAVING INTER-PANEL INSULATING INSERTS
The invention relates to a method for manufacturing a sealed and thermally insulating tank wall comprising: providing a thermally insulating barrier comprising two insulating panels delimiting an inter-panel space, providing an insulating insert comprising a wrapper completely covering an insulating core, inserting a suction nozzle of a suction system into the insulating insert through an orifice in the wrapper, applying a vacuum pressure in the insulating insert so as to reduce the thickness of the insulating insert through vacuum pressure, inserting the insulating insert into the inter-panel space while maintaining the suction of the suction system, when the insulating insert has been inserted into the inter-panel space, removing the suction nozzle from the insulating insert.
Membrane type insulation system for cryogenic LNG carrier cargo tank and liquefied gas fuel container
Disclosed is a membrane type insulation system for LNG carrier cargo tank and liquefied gas fuel container wherein a corrugation finishing membrane formed of Invar steel is welded to a secondary membrane connecting portion or a primary membrane connecting portion in order to seal corrugations at a corner portion of a cargo tank in a structure wherein at least one of a primary membrane and a secondary membrane is formed of an SUS material having corrugations, thereby improving work efficiency while reducing manufacturing costs through elimination of a separate angled piece for connection between corrugations on adjacent walls at the corner portion.
