Abstract:
Welding methods are provided for use in joining ultra-high strength, low alloy steels to produce weldments having tensile strengths greater than about 900 MPa (130 ksi) with weld metals having fracture toughness suitable for cryogenic applications according to known principles of fracture mechanics.
Abstract:
A container for holding a solid, liquid and/or gaseous phase product therein and for use within a transportable or stationary support structure. The container maximizes the compressed product volume contained therein and prevents liquid and/or contaminant entrainment during gaseous product delivery from liquid phase product. The system allows for product withdraw when the level is above the delivery valves using, at a minimum, two delivery legs linked by a compartment or housing that connects the delivery point and a container head space via a removable manway.
Abstract:
A high pressure cryogenic fluid dispensing system features a tank containing a cryogenic liquid with a liquid side and a head space there above. A pressure building coil featuring a section of parallel heat exchangers and a section of series heat exchangers receives liquid from the tank through a pressure building regulator valve and a pair of surge check valves. The liquid flashes to gas in the section of parallel heat exchangers and the resulting gas is forced to the section of series heat exchangers where it is pressurized and warmed. The gas may be directed to a warming coil for dispensing and to the head space of the tank to rapidly pressurize it. Gas traveling to the head space flows through an vapor space withdrawal control valve. The vapor space withdrawal control valve and pressure building regulator valve may be automated via a controller that provides pressure building when the tank pressure drops below the system operating pressure.
Abstract:
Es wird ein Speicherbehälter, insbesondere für kryogene Flüssigkeiten, mit einem äußeren (1) und wenigstens einem inneren Behälter (2), wobei sich zwischen dem äußeren (1) und dem oder den inneren Behältern (2) ein Isolationsraum (3) befindet, beschrieben. Erfindungsgemäß weisen der äußere (1) und/oder der innere Behälter (2) Mittel zum Verstärken der Behälterwandungen auf. Hierbei können die Mittel zum Verstärken der Behälterwandung des äußeren (1) und/oder des inneren Behälters (2) als wenigstens ein auf der Behälterwandung des äußeren (1) und/oder des inneren Behälters (2) angeordneter Steg (4) und/oder als wenigstens ein im wesentlichen dem Querschnitt des inneren Behälters (2) angepasstes Stützblech (5, 5') ausgebildet sein.
Abstract:
L'invention a trait à un capotage de protection type ouvert pour récipient de fluide, en particulier pour bouteille de gaz, composé d'un corps de capotage (1) en matériau polymère comprenant un insert (2) en métal ou en alliage métallique taraudé (10). De préférence, l'insert (2) a sensiblement une forme de bague à paroi interne taraudée et le corps (1) de capotage est surmoulé autour de l'insert (2) taraudé. De plus, l'insert (2) peut comporter un ou plusieurs évidements (7) et/ou un ou plusieurs renforts (6) sur sa paroi périphérique externe. En outre, l'invention concerne aussi une bouteille de gaz munie d'un tel capotage de protection, ainsi que le procédé de fabrication d'un tel capotage de protection.

Abstract:
Fuel storage and delivery systems are provided for storing pressurized liquefied natural gas (PLNG) fuel 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) and delivering vaporized PLNG fuel on demand for combustion in an engine (24). The fuel storage and delivery systems have fuel storage containers (10) that are constructed from 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). While not limited thereto, the present invention is especially useful for automobiles, buses, trucks and other vehicles with engines (24) designed to operate through combustion of natural gas.
