    Abstract: A boss includes a neck and a flange that extends radially outward from the neck. The neck includes a bore therethrough with a longitudinal axis. The flange includes an exterior surface, an interior surface, and a peripheral surface at a farthest extent from the longitudinal axis. The peripheral surface connects the interior surface and the exterior surface and includes, along any radius of the boss, a first circumferential ridge and a second circumferential ridge, wherein the first circumferential ridge is located closer to the exterior surface than the second circumferential ridge. In another aspect, a pressure vessel includes a boss and a liner. In yet another aspect, a method of assembling a pressure vessel is described, which includes inserting the boss through the aperture of the liner and connecting the boss and liner so that the peripheral surface of the boss mates with the perimeter surface of the liner.

    Abstract: A boss assembly for a pressure vessel includes a boss, a fitting, a first seal and a second seal. The boss includes a bore with an inner surface and a first stop feature. The fitting is configured for at least partial insertion into the boss to prevent fluid communication between an interior and an exterior of the pressure vessel, the fitting including an outer surface and a second stop feature. Each of the first and second seals is positioned along the outer surface. The fitting is movable between first and second positions. In the first position, the first seal is sealingly engaged between the inner and outer surfaces and the second seal is not sealingly engaged therebetween. In the second position, the first seal is not sealingly engaged between the inner and outer surfaces, the second seal is sealingly engaged, and the first and second stop features mutually contact.

    Abstract: In assembly of a pressure vessel and mount, the pressure vessel has a diameter and a length and includes a substantially cylindrical body and a boss neck. The substantially cylindrical body has a domed end and tapers from a portion having the diameter to the boss neck at the domed end. The mount includes a central and first and second flanges. The central plate has an aperture therethrough configured to accept a portion of the boss neck. The first and second flanges are located at opposed first and second sides of the central plate, respectively, and are configured to extend toward the body. The assembly occupies no more than a rectangular prism space defined by the length, a width equal to the diameter, and a height equal to the diameter of the substantially cylindrical body.

    Abstract: A pressure vessel has an interior chamber and includes an outer shell, a boss, and an internal liner disposed within the outer shell. The boss includes a port extending between the interior chamber and an exterior of the pressure vessel; and an annular flange extending radially from the port and having an exterior surface and an interior surface. The liner includes an exterior portion adjacent the exterior surface of the flange; an interior portion adjacent the interior surface of the flange; and a vent in the interior portion. A method for forming a pressure vessel includes mounting a boss on a mandrel, flowing a non-metallic polymer around a flange of the boss to form an internal liner of the pressure vessel, forming a vent in an interior portion of the liner; and forming an outer shell surrounding the liner and at least a portion of the flange of the boss.

    Abstract: A system and method of predicting impending failure of a pressure vessel include a pressure vessel, a fluid source, a line coupled to the pressure vessel and to the fluid source, an apparatus, a sensor and a controller. The apparatus includes a conduit and a containment structure. The containment structure includes a cavity separated from an interior of the conduit by a portion of a conduit wall of the conduit. The sensor is configured to determine a value of a physical property in the cavity. The controller is in signal communication with the sensor and configured to detect a change in the value. The method includes determining a first value of a physical property in the cavity, experiencing a failure of the conduit wall, determining a second value of the physical property in the cavity, and detecting a difference between the first and second values.

    Abstract: A pressure vessel includes a shell, a liner, and a boss. The liner is positioned within the shell and defines the interior environment. The boss is located at a first interface between the shell and the liner. The boss includes a cavity and a venting structure located in the cavity. The cavity is located at a second interface between the liner and the boss, and the cavity is located at an interior surface of the boss in communication with the interior environment. A gas vent path is defined from the first interface, through the venting structure, and into the interior environment of the pressure vessel. The disclosure also describes a boss for a pressure vessel and a method of manufacturing the boss. The boss includes a port, a flange, a cavity and a gas venting structure. The cavity and gas venting structure are located on an interior of the flange.

    Abstract: A boss configured for attachment to a pressure vessel includes a first bore therein and a bearing disposed at least partially within the first bore. A system for supporting a pressure vessel on a vessel mount includes a boss, a bearing, and an attachment element. The boss is attached to the pressure vessel and has a first bore therein. The bearing is disposed at least partially within the first bore and has a second bore therethrough. The attachment element is configured to be affixed to the vessel mount, wherein a portion of the attachment element extends through the second bore and is slidable within the first and second bores substantially along a longitudinal axis of the pressure vessel. A method is described for supporting a pressure vessel on a vessel mount.
