Definitions

  • This invention relates to pressure vessels having at least one open end and to end closures and side ports therefor. More specifically, it relates to cylindrical pressure vessels designed for reverse osmosis pressure driven filtration operations, particularly to vessels which provide full-bore access to accept elongated, cylindrical filtration media cartridges. Even more particularly, it relates to improved end closure arrangements for such pressure vessels. It also relates to methods for making such pressure vessels of this general type and particularly to those designed for pressure driven filtration operations, especially filtration using filter cartridges, and more particularly to making vessels suited for sidewall porting to provide fluid flow couplings through the cylindrical sidewall of the pressure vessel.
  • Cylindrical pressure vessels have many industrial applications, including use in the field of filtration.
  • Vessels used in filtration are often of the type made from a resin-coated fiberglass shell and having a fully open end that must be closed by a separate closure. Further, one or more side ports are often attached to a cylindrical side wall of such a vessel.
  • Counterboring creates a flat surface allowing standard o-rings or other less-expensive sealing means to be used. However, counterboring cuts into structural glass fibers which weakens the vessel.
  • the present invention provides a pressure vessel comprising a cylindrical side wall formed from resin-coated fiberglass and a relief area onto which a flange of a side port can be attached, the relief area extending outward from the cylindrical side wall.
  • the vessel further comprises a planar mating surface at an outside extent of the relief area, and a bore in the mating surface for accommodating a cylindrical port having a flange.
  • the present invention provides a method of forming a resin-coated fiberglass pressure vessel having a relief area in a cylindrical sidewall of the vessel.
  • the method comprises the steps of: providing a mandrel having a cylindrical forming surface; providing a side port spacer on the mandrel, the side port spacer having a proximate end that conforms to and mates with the cylindrical forming surface of the mandrel and having a planar distal end for forming a mating surface of the relief area; winding a fiberglass material around the mandrel and the spacer to form a cylindrical pressure vessel having a relief area; impregnating the fiberglass material with a resin; and curing the resin.
  • the present invention provides a metallic insert ring for imbedding in the full bore open end of a composite pressure vessel.
  • the insert ring comprises a generally annular body, a cross section of the body having a height extending radially to the body and a width extending axially to the body, and an annular groove in an inside surface of the body.
  • a ratio of the height to the width is less than 0.7.
  • the present invention provides a method and apparatus for forming a pressure vessel 10 having a relief area 12 onto which a flange 14 of a side port 16 can be attached.
  • Examples of pressure vessels of the type used in the present invention are disclosed in commonly owned U.S. Patent Nos. 6,165,303 and 5,720,411 to Darby et al.,
  • the present method and apparatus provides a more efficient, lower cost approach to providing a relief area than known methods.
  • the present invention results in a configuration which more effectively utilizes the glass fibers of the pressure vessel shell 18 than known configurations.
  • a cylindrical mandrel (not shown) of a known design is used as a form upon which to build the pressure vessel shell 18.
  • a side port spacer 20 is provided having a concave surface 22 of a shape which is complementary to the cylindrical surface of the mandrel.
  • the side port spacer 20 is designed to conform intimately to the cylindrical mandrel.
  • the side port spacer has a flat surface 24 opposing the concave surface 22.
  • the side port spacer 20 is placed on the mandrel. Then, reinforcing fibers combined with a resin, such as fiberglass wound with thermoplastic resin fibers or a thermosetting impregnating resin, are wound around the mandrel and side port spacer 20. The resin is then hardened, forming a rigid pressure vessel shell 18. In the case of fiberglass wound with thermoplastic resin fibers, the resin is sintered or melted under the influence of heat and then cooled, allowing the heat-softened thermoplastic to harden.
  • Other reinforcing fibers such as glass, carbon, KEVLAR (available from Dupont), metal, aramid, silicon carbide and boron may also be used.
  • thermoplastic fibers include, for example, polyethylene, polybutylene terephthalate, polyethylene terephthalate and nylon.
  • thermoset plastics such as epoxy, vinyl ester and polyester, can be used in place of the thermoplastic fibers.
  • the finished pressure vessel shell 18 is removed from the mandrel and the side port spacer 20 is removed from the shell 18.
  • a flat surface 26 formed on the inside of the cylindrical shell side wall corresponds to the flat surface 24 of the side port spacer 20.
  • a port hole is formed in the flat surface 26 of the pressure vessel shell 18.
  • the side port 16 having an annular flange 14 is inserted through the port hole.
  • the side port flange 14 bears and seals against the flat surface 26 in the relief area 12 surrounding the port hole.
  • the port hole is provided with an inside thread 27.
  • the side port 16 is provided with a corresponding outside thread 28. Thereby, the side port 16 can be inserted and threaded into the port hole.
  • An annular groove 30 in the side port flange 14 accommodates a standard o-ring 31. When the side port flange 14 is tightened against the flat surface 26 by way of the threads 28, the o-ring 31 is captured between the flat surface 26 and the flange 14 to provide a seal.
  • another advantage of the present invention over the prior art concentric relieved region is that the flat surface 26 permits the glass filaments that are capturing the port flange 14 to approach the loaded area at a steeper angle, and therefore carry a greater load.
  • FIG. 4 shows an alternative embodiment of a side port spacer according to the present invention.
  • FIGS. 5 and 6 show a metallic insert ring 32 for imbedding in the composite shell 18 of a full-bore opening vessel 10.
  • the ring 32 acts to reinforce the shell 18 where a closure 33 is attached.
  • An inside annular groove 34 of the ring 32 also supports a locking ring 35 that holds the closure 33 in place.
  • the insert ring 32 has a cross-sectional radial height (H) to axial width (W) ratio of less than 0.7, as compared to prior art ratios of greater than 1.0.
  • the lower ratio configuration moves the centroid of the insert ring's cross-sectional area 36 to a point which permits a reversal of the direction of the torque applied to the composite shell 18 by the loaded insert ring 32.
  • the conventional insert ring when loaded by the pressurized fluid within the vessel, applies a torque to the shell which concentrates a compressive bearing stress load adjacent to the inner diameter of the shell wall. Reversing the direction of the torque applied by the insert ring 32 on the shell shifts the maximum loading to the interior of the composite wall, i.e. the region adjacent to the outer diameter of the insert ring 32.
  • insert ring 32 is shaped to minimize or eliminate the region adjacent to the ring 32 which would inherently be devoid of fiberglass due to the bridging of the fiberglass strands as they traverse the insert ring 32.
