Abstract:
A pressure vessel is produced for storing and transporting CNG. The vessel comprises a body defining an internal volume in which the CNG can be stored, and an inlet for loading the CNG into the vessel. The body of the vessel comprises a structural shell made entirely of a fibre-reinforced fibre-wound composite material, which is provided with fibres to carry mechanical loads and a matrix to keep the fibres together and to make the composite impermeable to the CNG. Because the vessel is not provided with any liner, the CNG is in direct contact with an inner side of the structural shell.
Abstract:
A method of producing a pressure vessel, and the corresponding pressure vessel, wherein the pressure vessel is comprised of different types of structural elements, one of the structural elements being comprised of a metal substrate having a liner material adhering to the substrate in adjoining linear areas; and orientated so that adjoining linear areas of lining material are orientated longitudinally with respect to a completed pressure vessel.
Abstract:
The present invention is directed to a pressure vessel comprising a conductive composite boss wherein the composite boss is isolated from contact with materials with different electrical potentials so as to substantially eliminate the possibility of galvanic corrosion.
Abstract:
The present invention relates to a fire resistant pressure vessel in which the inclusion of fire resistance does add appreciably to the overall weight of the vessel over a similar vessel that is not fire resistant.
Abstract:
A ship comprising a plurality of pressure vessels, there being a first set of pressure vessels of a first length, a second set of pressure vessels of a second length, and a third set of pressure vessels of a third length, the first, second and third lengths differing from one another. The vessels are typically arranged vertically, and the ship can be a multi-hull ship.
Abstract:
A pressure vessel for storage and transportation of CNG comprises a body, which defines an internal volume in which the CNG is stored and transported. An inlet is provided through which the CNG can be loaded into the internal volume of the vessel. At the end of said inlet there is a CNG expansion section through which the CNG expands into the vessel when loaded. The pressure vessel further comprises a CNG loading appendage for injecting the CNG at a point inside the internal volume of the vessel, thereby increasing the space between the expansion point of the CNG and the walls of the vessel.
Abstract:
The present invention relates to pressure vessels comprising a composite dome and metal cylindrical center section where the dome is of such a thickness as to be capable of withstanding the pressure exerted by a fluid contained in the vessel but the cylindrical center section is not. To overcome this shortcoming the cylindrical center section is hoop-wrapped with a filamentous composite. Methods of coupling the dome to the center section are also set forth.
Abstract:
This invention is directed to a polymeric pressure vessel comprising a wall prepared by living polymerization such that the wall comprises a single layer of polymer having two sub-layers, an inner sub-layer that is not a composite and an outer layer that is.
Abstract:
A storage system for compressed natural gas which includes at least one storage vessel for storing CNG and a cooling station wherein the storage vessel is connected to the cooling station so that CNG may be stored in the storage vessel after had been passing through the cooling station and once the stored gas conditions fall out a set range, it is cooled in the cooling station, and returned to the storage vessel, wherein the storage vessel is thermally insulated from the exterior thereof thanks to the composite materials and especially glass-reinforced polymers whose pressure vessels are made.
