Abstract:
A gas storage structure includes: a container and a continuous coiled pipe supported by the container, the continuous coiled pipe including a major portion formed of thin walled pipe and a thick walled pipe defining an end of the continuous coiled pipe, the thick walled pipe having a wall thickness thicker than the thin walled pipe, the thick walled pipe being welded at a welded joint to the major portion to place an inner diameter of the thick walled pipe into communication with an inner diameter of the major portion and the thick walled pipe being connected to the container, while the major portion is free of any rigid, such as welded, connections to the container.
Abstract:
An article is provided that can be used as a heating source for various applications. The article includes an environmentally friendly gaseous fuel mixture within a gas cylinder that is both non-corrosive and refillable. More specifically, the gaseous fuel mixture contains hydrogen and methane. Methods of using the article as a heating source are also provided.
Abstract:
Provided is an independent tank, and a manufacturing method therefor, for which local bending stress occurring on the vicinity of a boundary portion (welded portion) can be reduced without increasing plate thickness. An independent tank has at least one curvature change portion in which the curvature along the axial direction of plate members that form the tank changes along the axial direction. Both the inner peripheral surface and the outer peripheral surface of the plate member on the small curvature side are not flush with respect to the inner peripheral surface and the outer peripheral surface of the plate member on the large curvature side. The plate thickness center of the plate member on the small curvature side is offset toward the radial direction inner side or the radial direction outer side with respect to the plate thickness center of the plate on the large curvature side.
Abstract:
A method of manufacturing a liner for use in a pressure vessel includes a cold drawing process that shapes a transition zone (20b) part of an aluminium alloy liner shell (10). The transition zone (20b) links a thinner walled drum part (18) and a thicker walled end region (20a), which is at an open top of the shell. The transition zone (20b) may be shaped by the cold drawing process such that it reduces susceptibility of the shell to fracture during removal from a cold drawing press and also redistributes shell material in preparation for a subsequent process in which a threaded neck is formed from the end region (20a). This process is particularly suited to processing harder aluminium alloy materials such as AA7060 or AA7032.
Abstract:
A system for storing natural gas comprises a plurality of straight sections of tube. The plurality of straight sections of tube are dense packed. The plurality of straight sections of tube are configured to fill a designated volume.
Abstract:
A composite pressure vessel includes a liner to contain a pressurized fluid and a composite layer formed on at least a portion of an exterior surface of liner. The composite layer includes a third generation advanced high strength steel filament reinforcement embedded in a polymer matrix.
Abstract:
Bag (1) for application in an external container (2) for forming a pressure vessel (2) with two separate compartments (3,4), that is manufactured from an elastic and stretchable material that is such that the bag (1) can stretch from an unstretched state to a stretched state when the bag (1) is filled with a product (9) or when the bag (1) is inflated with air, whereby the stretching of the bag (1) is reversible and whereby the stretch is so substantial that the bag (1) can be used for constructing pressure vessels (2) of diverse dimensions.
Abstract:
A gas cylinder (1) formed of a cylinder body (2) with a tubular wall (5) having at least a first tubular portion (11) that is enlarged, and at least a second tubular portion (12) that is adjacent and narrowed relative to the first tubular portion (11).
Abstract:
Disclosed herein is a composite pressure vessel with a liner having a polar boss and a blind boss a shell is formed around the liner via one or more filament wrappings continuously disposed around at least a substantial portion of the liner assembly combined the liner and filament wrapping have a support profile. To reduce susceptible to rupture a locally disposed filament fiber is added.
Abstract:
A container for storing compressed gas includes a plurality of aligned glass capillaries extending into a tubesheet. Each of the capillaries has an open end flush with a front face of the tubesheet. An end cap having a gas outlet connectable to a compressed gas valve or conduit is fitted to the tubesheet in gas-tight fashion to form a high pressure space defined by inner surfaces of the capillaries, the front face of the tubesheet, and inner surfaces of the end cap.
