Abstract:
The invention relates to a method for the production of a bladder accumulator (10) which separates two media chambers (16, 18) from one another in a storage housing (12) by means of a bladder body (14), comprising at least the following production steps: - extruding a plastic tube over the bladder body (14); - shaping the plastic tube with the integrated bladder body (14) in a molding tool that corresponds to a predeterminable plastic core container (20), and - winding at least one plastic fiber from the outside on the plastic core container (20) for the purpose of creating the storage housing (12).
Abstract:
This invention is directed to a method of decreasing the rate of escape a gas from a breached containment system by introducing into the containment system a plurality of objects that create a tortuous path for the gas to get to the point of breach thereby substantially reducing the degree of damage done by the breach.
Abstract:
The present invention relates to covering for a gas storage (100). The covering comprises an interior membrane (102) which is mountable to the gas storage (100) for at least partially enveloping an inner volume (Vs,i) of the storage (100) for storing industrial gas. Further, the covering comprises an exterior membrane (101) which is mountable to the gas storage (100), wherein the exterior membrane (101) covers the interior membrane (101) in such a way that an outer volume (Vs,o) for storing support gas is generated between the exterior membrane (101) and the interior membrane (102). The exterior membrane (101) comprises a material with an ultimate elongation of more than 100%.
Abstract:
The present invention concerns a metal membrane for a low-temperature-fluid storage tank wherein longitudinal and transverse corrugations are formed and both corrugations intersect each other. In the intersection of the corrugations, a bidirectional expandable member connected to each corrugation is formed so that the bidirectional expandable member is longitudinally and transversely expandable. The bidirectional expandable member is protruded and is shaped like a pyramid, a dome or a cross. Each metal membrane is welded into a unit panel and the edge of each metal membrane is welded with the common edge of another adjacent metal membrane to keep a cargo warehouse air-tight, and ultra-low-temperature LNG is stored inside the cargo warehouse, so when the metal membrane contracts due to thermal deviation, the present invention reduces plane rigidity and, at the same time, equalizes plane rigidity of two intersecting directions. Accordingly, durability is improved, air-tightness is maintained and storage of low-temperature liquid is stabilized, regardless of extreme thermal deviation. Furthermore, fabrication of the storage tank is improved because the present metal membrane is easily clamped by a clamping unit of a welding robot or a transfer device.
Abstract:
The invention relates to a hydraulic accumulator, in particular a bladder accumulator, comprising two at least partially adjacent plastic casings (12, 14). The first plastic casing (12) comprises a collar part (16) at least at one end thereof. The aim of the invention is to produce a leakproof accumulator arrangement which is economical to produce. To achieve this, a gap opening (24) between the casings (12, 14) extends up to a point, at which the casings (12, 14) are positioned together in a coaxial manner, and a disk valve (50) is provided as a valve for controlling the supply and discharge of the medium in the opening (10).
