摘要:
A high-pressure vessel fabrication and methods of fabrication are disclosed. An exemplary vessel includes a gas-tight inner liner fabrication, an outer structural overwrap fabricated by reinforcing a filament winding onto the gas-tight inner liner, and an overwrap polymerization. Prior to rotational molding of an inner seamless polymer liner, nozzles are manufactured for subsequent installation into a rotational mold that have grooves on both surfaces of embedded portions and a raised ring shoulder on the surface of a bore near an outlet of the nozzle.

A metallic liner for a composite reinforced high pressure gas cylinder is composed of a seamless metal tube contoured with a top dome and bottom dome. The liner is further composed of a seamless top metal end cap having a mating shape of the top dome and a seamless bottom metal end cap having a mating shape of the bottom dome. Alternatively, an extruded cup is shaped to a dome at the open end and one or two seamless metal end caps are used. In the method of manufacturing, the top and bottom ends of the metal tube are contoured, the end caps are produced, and one or two end caps are attached to the ends of the tube.

The present invention is a tank suitable to contain high pressure fluids, especially for compressed natural gas used for automotive purposes. The tank has a discoid shape to be easily placed on board of vehicles. The tank comprises a sealed internal core and an external coating made through a twisted coats fiber wrapping of composite material with a very high mechanical tensile resistance. According to some executive variants, the tank internally comprises a reinforcing structure made up of a plurality of elements welded in contact with the internal surface of the core.

Plastic inner liners (3) are used as core material for filament winding of composite pressure vessels. These vessels are used for Compressed Natural Gas (CNG) in Type 4 Cylinder and as alternative replacement of existing LPG steel cylinder. The inner liner (3) has at least one opening to install the valve which is connected liquid and gas tight to the surface of the filament wound fiber reinforced cylinder surface.

Tank (1) for storage or treatment of fluids, comprising a bottom, a wall, and a gas tight lining arranged on the wall, distinguished in that the gas tight lining is made from bands of thin sheets arranged side-by-side such that the wall is covered, adjacent bands being held together with a against the underlayer tightly fastened clamping moulding, and the bands being sealingly joined by seam welds to the clamping moulding. Method for arrangement of the gas tight lining.
摘要:
A process prevents a reduction in the strength of the joint between the liner components, and assures high productivity without impairment. The peripheral walls (6, 7) of the liner component (4) and each of the second liner components (5) are brought into contact with each other, a probe (22) of friction agitation joining tool (20) is placed into the two liner components across the contact portions thereof, and the probe (22) in rotation is thereafter moved relative to the two liner components (4, 5). Assuming that the number of revolutions of the probe (22) is R rpm and that the speed of joining of the two liner components (4, 5) is V mm/min, R/V is in the range of 2

摘要:
A storage system and its manufacturing method, for an adsorbing gas includes a plurality of briquette units situated within a storage tank. Each briquette unit includes an open vessel or liner and compressed gas-absorbing particulate matter, which particulate matter includes activated carbon, zeolite, and other appropriate hydrocarbon gas and/or hydrogen adsorbing materials. Optionally, each unit can include a wrapper for preventing circulation of the particulate matter within the storage tank and the storage system can include a mechanism for supplying or removing heat to at least one of the briquette units. Methane powered vehicles, such as automobiles, buses, trucks, and ships can include the above described storage system with compressed methane-adsorbing particulate matter.
