Abstract:
This invention relates to a pressure vessel having a one-piece polymeric composite with a weldable metal fitting such that the pressure vessel can be coupled to a source of compressed fluid by a welded connection.
Abstract:
A connection element is provided for a pressure tank. The connection element is to be introduced into an opening of the pressure tank. The connection element includes a stopper element and a counterelement at least partially enclosing the stopper element. An outer side of the stopper element and an inner side of the counterelement form a tapering clearance, with the result that a tank wall of the pressure tank can be clamped in the clearance of the connection element.
Abstract:
A tank for safely storing a fuel in a high-pressure gaseous state, and a method for manufacturing the tank are provided. The fuel gas storage tank includes a composite material that forms a tank shell and a liner disposed under the composite material. In addition, the liner has a structure in which a metal coil is integrally formed within the liner.
Abstract:
A gas containing tank includes: a tank body that contains a gas; a safety valve that discharges the gas contained in the tank body when being heated above a predetermined temperature; a conduction member that is provided outside the tank body, and transfers heat to the safety valve; and a heat insulation member that covers at least a part of the conduction member, and has higher heat insulation than that of the conduction member. The predetermined temperature is lower than 600° C., and the heat insulation member has a heat-resistance temperature lower than 60° C. and higher than the predetermined temperature.
Abstract:
A system and method of receiving field gas from a compressor station pipeline, and compressing the gas at a remote location with a modular compressor. The compressed gas is collected in a container and transported to a wellsite for use at the wellsite. The gas from the pipeline is directed to the container, and diverted to the modular compressor when pressure in the container approaches pressure in the pipeline. The modular compressor discharge is piped to the container, so that the container is filled with additional gas and at the discharge pressure of the modular compressor.
Abstract:
A valve assembly for controlling the release or delivery of a fluid or other medium from a vessel. The valve assembly comprises an inlet, an outlet, valve means operable to selectively open or close fluid communication between the inlet and the outlet and lock means for engaging the valve means, wherein the lock means is configured to engage, in use, the valve means when it opens, thereby to lock the valve means in an open condition.
Abstract:
A second protective member (62) is provided to cover a thin wall portion and its periphery of a second tank head section (92), so as to protect the thin wall portion. The thin wall portion is a region of the second tank head section (92) in which a reinforcing layer (20) has a smaller wall thickness. The second protective member (62) has a double layer structure including an inner layer made of polyurethane and an outer layer made of a material mixture of polyurethane and expanded graphite. This structure suppresses the mass and the volume of a pressure vessel from being increased by the presence of a protective layer.
Abstract:
Method for dispensing a compressed gas to receiving vessels wherein a threshold pressure of compressed gas needed to supply the dispensing system is calculated, the threshold pressure depending on the anticipated time-averaged dispensing rate for a time period. Compressed gas is passed from a plurality of supply vessels, for example a tube trailer, to a plurality of storage vessels, and dispensed from the plurality of storage vessels to a plurality of receiving vessels. The supply vessel providing the compressed gas is required to have a compressed gas pressure greater than the calculated threshold pressure.
Abstract:
A reduced-weight container or vessel for storage, transportation and processing gases and liquids under pressure has a plurality of hollows formed in the outer wall, resulting in a reduced weight without compromising the structural integrity.
Abstract:
An insert for a cryogenic capable pressure vessel for storage of hydrogen or other cryogenic gases at high pressure. The insert provides the interface between a tank and internal and external components of the tank system. The insert can be used with tanks with any or all combinations of cryogenic, high pressure, and highly diffusive fluids. The insert can be threaded into the neck of a tank with an inner liner. The threads withstand the majority of the stress when the fluid inside the tank that is under pressure.
