Abstract:
A container is provided for storing pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 °C (-190 °F) to about -62 °C (-80 °F). The container is constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 °C (-100 °F).
Abstract:
A lower header (10) on the side of an inlet for a low-temperature liquid and an upper header (16) on the side of an outlet therefor are connected together via a plurality of external heat transfer pipes (22). In the interior of each external heat transfer pipe (22), an internal heat transfer pipe (24) is provided which extends from the inlet side end of the external heat transfer pipe (22) to a portion thereof which is short of the outlet side end of the mentioned pipe. Between the outer surface of the internal heat transfer pipe (24) and the inner surface of the external heat transfer pipe (22), a low-temperature liquid circulating passage (23) communicating with the interior of the lower header (10) is formed.
Abstract:
A cutting apparatus using a jet of cryogenic fluid and comprising a low pressure cryogenic fluid storage tank, a high pressure compressor (12), and a discharge nozzle (19) connected by lagged ducts. The operation of a heat exchanger (8) arranged between the storage tank (1) and the discharge nozzle (19) for cooling the discharged fluid to a constant set temperature is controlled by the output from a temperature sensor (31) at the inlet of the high pressure compressor (12). A cutting method carried out using said apparatus is also disclosed.
Abstract:
La présente invention porte sur un dispositif de tranfert d'hélium liquide entre deux appareils à des potentiels différents comprenant un premier 1 et un second 2 embout, un premier 3 et un second 4 tube métallique d'embout, un premier 5 et un second 6 tube métallique interne de transport de l'hélium liquide, des moyens de liaison isolants internes 7, des moyens de liaison isolants externes 8 sur le pourtour desquels sont disposées des ailettes 9 et un conduit de pompage 10.
Abstract:
La structure creuse selon l'invention est obtenue en courbant sur une partie de sa longueur un tube ondulé garni circonférentiellement dans le creux (2a, 2b, 2c) de ses ondes par une composition durcissable renforcée de fibres, puis en soumettant le tube ainsi courbé sur au moins une partie de sa longueur à un traitement permettant le durcissement de la composition durcissable. Le tube peut comporter des renforts longitudinaux (3b), (tresse ou nappes de fils hélicoïdaux à grand pas), les extrémités du tube pouvant être équipées de systèmes permettant la communication avec l'extérieur ou la fermeture étanche, la mise en forme définitive étant suivie d'un traitement de durcissement de ladite composition. L'enroulement du tube peut être effectué autour d'un noyau central ou tambour. La structure peut être utilisée comme conteneur de gaz comprimés.
Abstract:
A high-pressure container includes a plurality of body parts (20, 42, 70) arranged side by side, and each of the body parts (20, 42, 70) has a cylindrical shape and has an opening at at least one of its axially opposite end portions. The high-pressure container also includes a cap (28, 34, 76) configured to close the openings of the body parts (20, 42, 70) as a unit, and a communication channel (48) provided inside the cap (28, 34, 76) for communicating interiors of the body parts (20, 42, 70) with each other.
Abstract:
A vessel for storing fluid, the vessel including a liner having a liner body that defines: a liner cavity; a plurality of flexible connector portions that include a corrugated length that provides for flexibility of the respective connector portions, the connector portions having a first maximum diameter; a plurality of elongated tubing portions between the respective flexible connector portions, the elongated tubing portions having a second minimum diameter that is larger than the first maximum diameter of the flexible connector portions; and a plurality of taper portions coupling adjoining flexible connector portions and tubing portions configured to provide a transition between a smaller diameter of the connector portion and a larger diameter of the tubing portion.
Abstract:
The present invention is directed to a new concept for a large-scale high-pressure Honeycomb Set Tank in an ISO container and for its manufacturing facilities. A process for manufacturing a plurality of honeycomb cells with a high degree of accuracy is also provided.
