A high pressure tank includes: a supplying/discharging hole; and a cap having formed therein a cap-side path which is a part of a flow path. A repelling coating interposes between a liner-side end surface facing a resin-made liner, of a flange section configuring the cap, or a flange section-facing outer surface facing the flange section, of the liner. The repelling coating is formed of a material that repels a matrix resin of a fiber-reinforced resin configuring a reinforced layer.

Provided a multi-layered pressurized gas container, for example one containing carbon dioxide for use in a device or system for the preparation of a carbonated drink, and processes for its manufacture.

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.

Method of constructing a vault of a large storage tank for liquefied natural gas by first modeling the vault with a 3-D modeling software application, then partially building the vault with a framework and a first set of covering panels fixed on the framework where the panels do not touch each other, but leave a number of gaps between them, measuring the dimensions of the actual gaps between the panels using a 3-D scanner, producing a second set of panels according to the scanned dimensional data, and finally filled the gaps between the first set of panels with the second set of panels, which are much smaller than the first set of panels, making the building process earlier and more accurate, which are difficult issues in building large tanks for liquefied natural gas.

A vessel includes a body that defines an interior space. The body includes a first metal surface, a second metal surface, and a non-metallic material crimped between the first metal surface and the second metal surface at a joint. The vessel further includes a pressure relief device coupled to the body. The pressure relief device is configured to vent contents of the vessel to an exterior of the body. Upon exposure of the vessel to a temperature for a period of time, the second metal surface is configured to expand or bend to create a pressure relief route from the interior space to the pressure relief device, between the first metal surface and the second metal surface, and/or the non-metallic material is configured to melt to create the pressure relief route.

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 is provided for producing a pressure vessel from a metal liner, which is reinforced at an outer lateral surface thereof by fiber composite material having a resin matrix. In at least one production step, the resin matrix of the fiber composite material is subjected to an ultrasound treatment.

A high-pressure tank includes an assembly of a pipe split body having a pipe liner and a pipe reinforcement layer covering an outer circumferential surface of the pipe liner, first dome split body having a first dome liner and a first dome reinforcement layer covering an outer circumferential surface of the first dome liner, and second dome split body having a second dome liner and a second dome reinforcement layer covering an outer circumferential surface of the second dome liner. The pipe split body and the first dome split body are assembled such that the first dome liner is located in the outer portion of the high-pressure tank relative to the pipe liner. The pipe split body and the second dome split body are assembled such that the second dome liner is located in the outer portion of the high-pressure tank relative to the pipe liner.

Systems and methods for insulating vessels are disclosed. In one or more embodiments, the disclosure provides a vessel insulation system (e.g., for use with a reactor or pressure vessel), which includes a floating ring sized to circumscribe a top nozzle of a vessel; a plurality of straps connected to the floating ring, the plurality of straps extending downward from the floating ring and being positioned to run along a length of the outer shell of the vessel; and a plurality of segmented rings positioned to circumscribe the outer shell of the vessel and connected to the plurality of straps. The plurality of segmented rings is configured to support an insulation material circumscribing the outer shell of the vessel, which can provide effective securement of the insulation material around the outer shell without welding components on the vessel to secure the insulation material.

A method for manufacturing a tank unit includes performing a pressure resistance inspection on each of a plurality of high pressure tanks before connecting the high pressure tanks, and connecting a gas flow path to the high pressure tanks that have passed the pressure resistance inspection.
