A cryogenic liquid storage tank includes a base plate and side wall extending upwardly. The base plate and side wall include an outer leaf enveloping an inner leaf The outer leaf part of the base plate includes a lower, outer leaf concrete bottom plate on a substrate. The bottom plate is continuous with an outer leaf reinforced concrete layer of the outer side wall. An inward surface of the bottom plate and concrete layer of the outer leaf are lined with a continuous outer leaf metallic membrane. A bottom insulation layer is arranged above the outer leaf metallic membrane on the bottom plate. The inner leaf includes an inner leaf concrete bottom layer on the bottom insulation portion. The inner leaf metal membrane is lined with an inner leaf inner concrete layer. The outer leaf hoop stress reinforced outer concrete wall supporting an insulated dome structure.

A boss for a pressure vessel has a flange. The flange includes an interior keyway having an inner sidewall and a plurality of bores disposed on the inner sidewall. A pressure vessel includes a main body section and an end section. The end section includes a boss and the boss includes a flange. The flange includes an interior keyway having an inner sidewall and a plurality of bores disposed on the inner sidewall. In another aspect, a pressure vessel includes an outer shell, and inner liner and a boss including a flange with an exterior side and an interior side. The liner is mechanically integrated with the flange via a plurality of anchors, each anchor contacting the flange only on the interior side. A method of forming a pressure vessel includes providing a boss having a flange. The flange has an interior keyway having an inner sidewall and a plurality of bores disposed on the inner sidewall. The method comprises allowing a fluid polymer material to flow into the interior keyway and into the plurality of bores.

A boss for use with a vessel is disclosed. The boss includes a first component adapted to be formed in an opening of the vessel, wherein the first component includes a first coupling element, and a second component including a second coupling element, wherein the second coupling element engages the first coupling element to secure the second component to the first component, and wherein a liner of the vessel is disposed therebetween.
摘要:
An apparatus and method for suspending an inner tank within an outer tank to form a cryogenic storage tank. Opposing ends of the inner tank are suspended from the outer tank by suspension members. A preloading device facilitates the preloading of the suspension members to suspend the inner tank within the outer tank. The suspension members constrain the inner tank in a statically determinable manner so that a desired preloading and loading can be imparted upon the suspension members. The suspension members advantageously limit the parasitic heat leaks between the inner and outer tanks.
摘要:
A method for manufacturing a polymeric inner liner for a storage tank, particularly a hydrogen storage tank, comprising: providing a cylindrical body of polymer material, having a first open end and a first peripheral connection tab at the first open end, the cylindrical body comprising a structural layer and a barrier layer; providing a dome-shaped end cap of polymer material having a base with a cross-section essentially corresponding to a cross-section of the first open end of the cylindrical body and having a second peripheral connection tab at a peripheral end portion of such end cap; placing the end cap with its base onto the first open end of the cylindrical body and with the first and second peripheral tabs in contact with each other; and welding both peripheral connection tabs together. A storage tank made using such liner. Use of such tank for storing hydrogen.

摘要:
A pressure vessel assembly, and method of use, for storing a gas at an elevated pressure. The assembly includes a vessel body having a rigid wall with an inner surface defining a storage chamber and with an inlet allowing the gas to enter the storage chamber. The assembly includes a flexible liner positioned within the storage chamber to be in fluid communication with the inlet to receive any fluid entering the vessel body. The liner is formed of an elastic inner layer contacting the gas and a metallic outer surface. The inflated, unrestrained liner volume is generally at least as large as the chamber volume and more typically, slightly larger. Stored gas contacts the inner surface of the liner and expands the liner from a smaller deflated volume until the outer surface of the liner contacts the wall of the pressure vessel.
摘要:
A pressure container comprising axially extending side walls formed of plastic extending between a top end and a bottom end. A metal top is attached at a top seam in pressure-containing relation to the top end of the side walls, and a metal bottom attached at a bottom seam in pressure-containing relation to the bottom end of the side walls. Optional top and bottom beads are formed in the side walls to aid in sealingly securing the metal top and bottom to the side walls. A method for containing pressurized materials by providing and filling such a pressure container is also shown.

A method of filling and sealing a gas capsule having (i) a hollow body portion and (ii) an elongate hollow neck portion having a free open distal end extending from the body portion is disclosed. The method is accomplished by applying a filling cap to the open end of the neck portion while evacuating the capsule and refilling with helium. Two crimping steps while pressure is maintained finishes the filling and sealing method.

A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The vessel may be formed in a variety of useful shapes and the tubes may have various internal and external cross-sections. The end caps may be filled with sintactic foam with canals leading to the passageway. Microtubes through the syntactic foam may connect the tubes to the passageway. The vessel is further strengthened by overwrapping with high-strength braiding material, hoop winding or by overlayment with high-strength fabric. The vessel is further strengthened by coating with plastic resin. Apparatus and methods for forming the cellular reservoir flexible vessels are described.
