Definitions

  • the liner includes a curved juncture member for joining the bottom and side plates of a conventional liner.
  • the juncture member has an elongated, radial corrugation projecting inwardly which has a plurality of transverse corrugations in it.
  • the juncture member absorbs rhultidirectional stresses due to thermal expansions and contractions and varying static pressures in the tank.
  • This invention relates to cryogenic containers for storage of natural gas and like gases which are stored as liquids under atmospheric pressure and at extremely low temperature. More specifically, this invention relates to an improved inner liner for cylindrically shaped cryogenic storage vessels for liquid natural gas.
  • the cryogenic containers are cylindrical and are comprised of a sealed outer vessel which is designed to accommodate, by itself, the stresses developed during the cooldown, filling and operation of the vessel.
  • a heat insulating material is positioned on the inside surfaces of the outer vessel in sufficient thickness to substantially reduce the heat input to the interior of the container.
  • Located inwardly of the insu-' lating layer is a flexible, thin-walled metal liner which isadapted to expand and contract during heatup or cooldown of the tank and during filling and emptying of it.
  • the flexible liner is not load bearing; rather it flexes in response to temperature changes within the container and transmits static pressures to the insulating layer and thus to the outer vessel.
  • inner liners A number of ingenious designs have beep developed for inner liners. They have been formed from sheet metal having corrugations which take up the expansion 1 and contraction due to temperature changes and variations in static pressure, thereby, reducing extraordinary hoop stresses which otherwise would be developed. Since the metal liners act only as sealing membranes, protecting the insulating layer from the contents of the cryogenic container, and have no structural significance other than to transmit stresses to the insulating layer and ultimately to the structurally significant outer walls, they must be sufficiently flexible to expand under the influence of the static force of the liquid contents of the vessel, to contract at the low temperatures encountered during cooldown of the vessel and to expand when the interior of the vessel is brought to ambient conditions. It will be appreciated that it is necessary to use thicker, and therefore more expensive and less flexible liners, where the stresses encountered are potentially great enough to cause failure of the inner liner.
  • a flexible juncture member for connecting liner plates in intersecting planes, having the following configuration.
  • the juncture member comprises a curved plate, attached at each end thereof to the liner plates, having'an elongated corrugation which extends inwardly, i.e. toward the inner part of the cryogenic container, the corrugation itself having a plurality of transverse corrugations the axes of which are essentially perpendicular to the inner surface of the curved plate.
  • a curved juncture member describing a right angle, is connected to the bottom and side liner plates of a cylindrical cryogenic container.
  • the elongated corrugation extends radially of the container and projects perpendicularly to the concave inner surface of the curved plate and that corrugation itself has a series of transverse corrugations in it.
  • the juncture member of this invention may be formed from a continuous, curved plate in which a'plurality of elongated corrugations are provided, or the juncture member may be comprised of a plurality of curved panels attached at their sides to one another and attached at their ends to the plates being connected.
  • Each of the panels may have one or more elongated corrugations, or, alternatively, each of the curved panels may have side flanges extending inwardly from the concave surface thereof, the flanges being welded at their edges'to the edges of the flanges of adjacent panels, to form the said elongated corrugation. In this fashion each panel forms part of two elongated corrugations.
  • the cylin drical side plate is also provided with a plurality of vertical, elongated, inwardly projecting corrugations.
  • the side plate may be formed from a continuous sheet having the described corrugations, or it too may be formed from a plurality of panels havingcorrugations therein 7 or side flanges which are welded to adjacent side flanges to form the corrugation.
  • FIGS. 1A and 1B are plan views of a cryogenic container with the top removed, showing the flexible inner liner in an expanded and in a contracted state respectively;
  • FIGS. 2A and 2B are elevation view taken along lines 2A 2A and 2B 28 respectively of FIG. 1;
  • FIG. 3A is a detailed elevation view of the juncture member of this invention in a contracted state
  • FIG. 3B is a plan view of the juncture member of FIG. 3A taken along lines 38 3B of FIG. 3A;
  • FIG. 4A is an elevation view of thejuncture member of this invention in an expanded state
  • FIG. 4B is a plan view of the juncture member of FIG. 4A taken along lines 48 4B of FIG. 4A;
  • FIG. 5 is a perspective view of a portion ofajuncture member
  • FIG. 6 is a side view of a cryogenic container showing a support system for the cylindrical liner.
  • reference numeral 12 refers to the outer wall of a cylindrical cryogenic container. Located inwardly of wall 12 is a layer of heat-insulating material 14. Numeral l6 refers to the bottom of the container. Located inwardly of heat-insulating layer 14 is a flexible liner 18 which includes a cylindrical side plate 20 and a flat bottom plate 22 of thin sheet metal. Cylindrical side plate 20 and flat bottom plate 22 are connected by means of ajuncture member 36 described in further detail below in connection with FIGS. 3, 4 and 5. Side plate 20 is supported along its upper periphery 28 by means of support guys 30. Guys 30 pass through guides 32 and over pulleys 34. A counterweight 36 balances the weight of the cylindrical side plate. As shown in FIG.
  • guys 30 are led through a plurality of fixed pulleys 38 each supported in the top structure 40 of the cryogenic container and thereafter through a series of vertically movable pulleys 42.
  • Movable pulleys 42 are, in turn, connected by means of a guy 44 to connectors 46 affixed to the top edge of cylindrical side plate 48.
  • the flexible metal liner 18 is shown in service, i.e. with an inventory of liquefied, natural gas 24 in the cryogenic container.
  • the side plate 20 and the juncture member 26 are under static pressure acting radially outward and they are forced into contact with heat insulating material 14.
  • the flexible inner liner 18 is shown contracted, i.e. when the tank is cooled down but before the liquid is introduced. In this service, there is a gap 21 between the flexible liner and the insulating material.
  • FIGS. 3A, 38, 4A, 4B, and 5 refers to a curved plate which connects flat bottom plate 22 with cylindrical side plate 20.
  • Juncture member 50 includes an elongated, inwardly projecting corrugation 52 extending radially with respect to the cylindrical container and projecting inwardly from the concave surface of the curved plate.
  • Corrugation 52 has a plurality of corrugations 54 whose axes are essentially perpendicular to the concave surface of the curved plate. Several of these axes are designated in FIG. 5 by reference numerals 56, 58 and 60.
  • FIGS. 3A and 3B showjuncture member 50in a contracted state whereas FIGS. 4A and 4B show juncture member 50 in an expanded state under the static pressure of the liquid natural gas in the container. It will be appreciated by referring closely to FIGS. 3A and 4A, that during the process of filling, the juncture member expands both outwardly and downwardly. Thus point 61 on FIG. 3A moves along the direction of arrow 63 to point 65.
  • .Iuncture member 50 expands to a flatter configuration under the static load, as shown in FIG. 4A, by the flattening out of corrugations 54 in elongated corrugation 52.
  • the outward radial movement of juncture member 50 under the static load causes the sides of elongated corrugation 52 to move apart as shown by comparison of the gap designated by reference numeral 77 in FIG. 38 with the gap designated by reference numeral 79 in FIG. 4B.
  • the juncture member absorbs radial expansion of liner 18 in elongated corrugation 52 and flattening expansion in corrugations 54.
  • the metal liner can adjust to the degree of cooldown and to the amount of static pressure and thus is adaptable to any conditions developed within the container.
  • bottom plate 22 expands and contracts when heated or cooled thereby radially displacing the lower end ofjuncture member 50.
  • the juncture member of this invention may be formed from a continuous length of curved sheet, by incorporating a plurality of elongated corrugations therein and then transversely corrugating the elongated corrugations.
  • it is fabricated from a plurality of curved panels, each of which has an elongated corrugation having the transverse corrugations shown. These panels are welded to one another at their side edges, and the ends of each panel are welded to the bottom and side plates of the liner.
  • the juncture member is formed from a plurality of curved panels having a channel-like configuration, two side flanges extending inwardly from the concave surface of the curved panels.
  • the side flanges on adjacent panels are designated by reference numerals and 71, the concave surface by reference numeral 72.
  • Flanges 70 and 71 are welded to one another at weld 74 along their upper edges to form the elongated corrugation.
  • Each panel has a second flange (not shown) which is, in turn, welded to a flange adjacent to it.
  • the flanges on the panels can be transversely corrugated and then mated and welded, or they can be first welded and then transversely corrugated.
  • the juncture member may be formed from a series of channel-like panels, the flanges of the channels forming the sides of the elongated corrugation and the edges of the panels being welded to the bottom and the side members as is shown, for example, in FIG. 18 by reference numerals 83 and 85.
  • the improved liner comprises an integral cylindrical side plate and curved juncture member, both of which are provided with inwardly projecting elongated corrugations, the juncture member only having the transverse corrugapanels, each of which has the elongated corrugations therein or, alternatively, the cylindrical side wall may be formed from a plurality of channel-like panels, the edges of the flangemembers on each channel being welded to the edges of adjacent flanges to form-th elongated corrugations.
  • a cryogenic container including a sealed outer vessel, an insulating layer on the inside surface of said vessel and an inner liner located inwardly of said insulating layer consisting of at least two plates positioned in angularly intersecting surfaces, a juncture member for connecting said, liner plates and absorbing multidirectional relative expansions thereof comprising: an inwardly concave curved plate attached at the opposed edges thereof having least curvature to said liner plates, said curved plate having an elongated corrugation extending inwardly from the concave surface thereof in the plane of greatest curvature, said corrugation itself having multiple corrugations therein the principal axes of which are essentially perpendicular to the concave surface of said curved plate.
