Abstract:
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.

Abstract:
Closure modules are coupled to and enclose ends of a multi-cell pressure vessel, especially a multi-cell pressure vessel having arcuate outer wall segments connected by internal web segments that define a plurality of cells in the pressure vessel. The closure modules each have an arcuate surface portion and at least one interfacing surface portion integrally connected at a marginal extent thereof with a marginal extent of the arcuate surface portion. The arcuate surface and interfacing surface portions define a closure module chamber and have peripheral edges. The arcuate surface portion of one of the closure modules abuts contiguously against an interfacing surface portion of an adjacent one of the closure modules. The closure modules are particularly useful for use with multi-cell tanks and vessel bodies, especially tanks and vessels suitable for storing liquid propane.
Abstract:
The invention relates to a tank (10) for storing compressed gas having a pressure of at least 15 Mpa, a casing layer (11) which encloses the hollow space (13) provided for storing the compressed gas, and at least one connection for loading and/or unloading the tank (10). In order to decrease the weight of the tank, the casing layer (11) can be constructed of plastic and/or a fiber material. According the invention, supporting elements (30) which are connected to the casing layer (11) are provided in the hollow space (13) of the tank (10) such that the tank (10) can be constructed in any geometric shape and can especially store gasses under high pressure. The supporting elements (30) can be constructed as filaments which are guided through the corresponding guiding canals (31). As a result, the supporting elements (30) assume the function of a seam. A liner (14) preferably constructed of plastic can be arranged on the inner surface (12) of the casing layer (11) in order to additionally seal the tank (10).
Abstract:
The present invention relates to a vessel (1) made of plastic or a similar material and intended for and suitable for containing internal overpressure. The vessel (1) consists of a tubular part (7), for example, with an end wall termination (2) and an end wall (4) joined to said part at the open end. The vessel may alternatively comprise two vessel parts, having essentially identical cross section in the joining plane and each with an integrated end wall termination, joined together. In accordance with the invention at least one of the vessel parts (7) has internal longitudinal reinforcing partition walls (11, 12), which together with the outer casing (8) of the vessel are joined to the attached end wall (4) or an opposite vessel part, so that the whole or a major proportion of the material in the boundary cross section between the vessel parts is capable of transmitting any axial forces which may arise as a result of internal overpressure in the vessel (1) between both end walls (2, 4) of the joined vessel. The invention also proposes a method for the manufacture of the vessel and its use.

Abstract:
A non-cylindrical pressure vessel storage tank is disclosed. The storage tank includes an internal structure. The internal structure is coupled to at least one wall of the storage tank. The internal structure shapes and internally supports the storage tank. The pressure vessel storage tank has a conformability of about 0.8 to about 1.0. The internal structure can be, but is not limited to, a Schwarz-P structure, an egg-crate shaped structure, or carbon fiber ligament structure.

Abstract:
Tank for storing pressurized water, including a plurality of hollow and tubular segments which are disposed adjacent and joined to each other and which are open on both sides, said tubular segments forming a tank body in which the pressure water is stored, the tank including a rectangular shape, an intake through which water enters the tank, and an outlet through which the water is evacuated from said tank. Two adjacent tubular segments are joined to each other by means of a connecting wall and the tank includes at least one cover on each side of the tank body in order to close said tank body. The connecting walls prevent a direct connection between the inside of two adjacent tubular segments, said tubular segments being communicated to each other through the covers.
Abstract:
A lightweight, ergonomically beneficial, hydrodynamic, and volumetrically efficient hybrid pressure vessel having at least two longitudinally extending, semi-cylindrical sections with flattened rib portions at a common interface between the sections. Additional longitudinally extending sections may be employed to provide additional internal volume. One or more apertures extend through the ribs to provide communication between sections. The pressure vessel comprises a cast metal material, optionally including exterior reinforcing structure for containing internal pressure.
