Abstract:
A pressure vessel is disclosed, the pressure vessel having an outer shell, an inner shell, and a temperature regulating device, the temperature regulating device adapted to regulate the temperature of a fluid stored in the inner shell during operation of the pressure vessel and to minimize curing time during manufacture of the pressure vessel.
Abstract:
This invention relates to gas vaporization and supply system that includes (a) a vessel suitable for holding a bulk quantity of a liquefied gas; (b) at least one heating source positioned on or near the vessel to supply energy to, or remove energy from, the liquefied gas; and (c) a heating source controller adapted to use process variables feedback for dynamically regulating the heating source and maintaining and regulating gas output. The process variables feedback results from cascading sequence control of at least two process variables. The process variables include pressure, temperature, and/or gas output flow rate. This invention also relates to a method for delivery of a gas, e.g., ultra high purity gases, from a liquefied state in a controlled manner to a usage site, e.g., a semiconductor manufacturing facility. This invention provides faster heating system response to fluctuations in customer demand, a longer heater life, and improved reliability.

Abstract:
In a screw structure of a high-pressure tank, there is an issue in that the strength of the screw section declines each time the screw section is used, and therefore an object of the present invention is to provide a tank having a structure which restricts decline in the strength of the screw section. In order to achieve this, the tank according to the present invention includes a mouthpiece having a mouthpiece screw section which is formed with a screw thread and has a larger diameter on the outer side than on the inner side in an axial direction of the tank, and a valve having a valve screw section which corresponds only to a portion of the mouthpiece screw section. In this tank, when installing a product valve on the mouthpiece, it is possible to use a screw portion of the mouthpiece of which strength has not declined, by using, for example, a test valve and a product valve having different positions of the valve screw sections.
Abstract:
A gas tank is provided which can ensure high gas barrier properties even with respect to a gas having a small molecular size, for example, a hydrogen gas. In a high-pressure gas tank comprising a resin liner inside an FRP layer, an oxide layer is formed on the inner surface of the resin liner. When a reinforcing fiber is wound around the outer surface of the resin liner by a filament winding process, air is beforehand enclosed inside the resin liner. Next, when the reinforcing fiber is thermally cured to form the FRP layer, the inner surface of the resin liner is thermally oxidized to form the oxide layer.
Abstract:
A pressure vessel arranging and integrating a plurality of vessel structures each including a cylindrical liner opened at both ends and a fiber reinforced resin layer covering the outer periphery of the peripheral wall of the liner. Dome-shaped communicating members bulging outward are fixed across both respective ends of the liners of the vessel structures, thereby making the interiors of these liners communicate with each other and closing the open ends of these liners. This pressure vessel can be installed with no wasted space, and also allows an increase in capacity.
Abstract:
A mounting system for a pressure vessel is disclosed. The mounting system includes a first retention cap, a second retention cap, and a plurality of fastening bands coupled to the first retention cap and the second retention cap, wherein the first retention cap and the second retention cap each include a concave inner surface and a mount, the concave inner surface substantially corresponding to at least a portion of an exterior surface of the pressure vessel to secure the pressure vessel between the first retention cap and the second retention cap.
Abstract:
A pressurized container includes two plastic casings (12, 14) and produces a leakproof container or storage arrangement which is economical to produce. A gap opening (24) between the casings (12, 14) extends up to a point at which the casings (12, 14) are positioned together in a coaxial manner. An external support ring (22) with a wedge-shaped tapering (26) extends to that point and is embodied as an individual piece or has at least two metal, ring-shaped individual segments (28, 30).
Abstract:
Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.
