The invention relates to a cryogenic tank comprising an inner shell intended to contain the cryogenic fluid, an outer shell arranged around the inner shell and delimiting a space between the two shells under vacuum, the outer shell extending in a longitudinal direction and having a plurality of reinforcing ribs distributed in planes that are perpendicular to the longitudinal direction, the ribs being formed by deformations, for example by knurling, on one and the same wall of the outer shell, wherein the tank also includes at least one reinforcing element for reinforcing at least part of at least one of the ribs, the reinforcing element comprising a strip rigidly connected to the two portions of the wall situated at the base and on either side of the rib.

Cladding of the interior of a component part of a pressure vessel is shown. A lining which conforms to at least a portion of the interior geometry of the component is positioned in the interior of the component. The lining is then pressed into the component past its yield strength. The lining is then fused to the component.

A method of manufacturing a high-pressure fluid vessel includes forming a first portion of a high-pressure fluid vessel with a molding process. The high-pressure fluid vessel includes a stack of capsules. Each capsule includes a first domed end, a second domed end, and a semicylindrical portion extending between and connecting the first domed end to the second domed end. The method further includes forming a second portion of a high-pressure fluid vessel with the molding process. The second portion of the high-pressure fluid vessel is positioned adjacent to the first portion of the high-pressure fluid vessel. The second portion of the high-pressure fluid vessel is welded to the first portion of the high-pressure fluid vessel.

A precast, prestressed concrete tank and method that facilitates construction of a primary inner tank within a secondary outer tank, and which permits for the construction of the primary inner tank after the secondary outer tank has been erected, but without requiring insertion through a top of the secondary outer tank, or by tunneling underneath the secondary outer tank, is disclosed. The primary inner tank has an inner wall and the secondary outer tank has an outer wall (precast, prestressed concrete) and wire windings. The primary inner tank is disposed inside of the secondary outer tank. The secondary outer tank has a plurality of first precast outer wall panels, and a temporary construction opening frame. The temporary construction opening frame defines an access doorway during construction of the tank. The temporary construction opening frame is disposed on a foundation base slab.

It concerns the invention of a pressure vessel (VP) which can be assembled from individual parts, and basically comprises: a plurality of wall modules (MP), at least one connection module (MC) for pipes or sensors, and closing modules (MF) that can be chosen from: have equal configuration and have different configurations. All of the modules have bores (105) distributed radially on their flat surfaces (101) and these bores (105) are distributed between a hollow drill (1051) with a seat (1151) and a torque screw bored (1052) (106) inserted therein attach a module to another adjacent module, with a sealing ring (104) therebetween.

A method for rapidly filling a compressed gas storage tank with a moderated temperature rise using a Coanda nozzle to inject the feed gas into the tank and using the Coanda nozzle to direct the feed gas along the inner surface of the storage tank; entraining the stored gas with the feed gas that is flowing under the influence of the Coanda effect to flow along the inner surface of the gas storage tank; and transferring heat from the flowing gas to the external walls of the tank. Also, a compressed gas storage tank for rapid filling with a moderated temperature rise comprising: a gas storage tank and a Coanda nozzle capable of directing feed gas that is injected into the gas storage tank along the inner surface of the gas storage tank.

Disclosed herein is a structure that comprises a tank including an outer cylindrical surface and a domed end. The structure also comprises a tank skirt positioned circumferentially around the tank. A wall of the tank and a wall of the tank skirt form two sides of a y-joint between the tank and the tank skirt. The y-joint includes a wedge structure positioned between the tank and the tank skirt. Additionally, a thickness of at least one of the wall of the tank or the wall of the tank skirt forming the y-joint tapers such that the thickness of the at least one of the wall of the tank or the wall of the tank skirt that tapers has a greater thickness at the y-joint than away from the y-joint.

A member for manufacturing a high-pressure tank liner is provided for producing a high-pressure tank liner with better welding quality between its liner halves than conventional products. The high-pressure tank liner is produced by welding together a pair of liner halves that have cylindrical bodies to be connected with each other on each joint portion having an opening at its one end. The member includes: the liner half; and a cap member that is easily attached to and removed from a communication tube of the liner half, which communication tube is formed on another end opposite to the joint portion between the liner halves and causes an inside and an outside of the high-pressure tank liner to communicate with each other.

A high-pressure tank liner includes a body portion formed from a cylindrical body, a diameter-expanded part formed into a cylindrical body at the body portion with a larger diameter than an outside diameter of a general part of the body portion, and a staircase portion including stairs and formed at a stepped portion between the general part and the diameter-expanded part of the body portion. A distance from a corner on the diameter-expanded part side of the stepped portion to a peripheral surface of the general part while passing through a corner of each stair constituting the staircase portion is shorter than a lateral width of roving formed from reinforced fibers arranged in such a way as to extend in a circumferential direction of the body portion.

A composite pressure vessel assembly includes a first vessel having a first inner layer and a second vessel having a second inner layer. An outer layer of the assembly is in contact with and substantially envelopes the first and second inner layers. A junction of the assembly has outer boundaries defined by segments of the first inner layer, the second inner layer and the outer layer. A cross-layered component of the assembly is disposed in the junction, the first and second inner layers and the outer layer for adding strength to the junction and restricting delamination.
