|Patent application number
|METAL-TO-COMPOSITE INTERFACES - The invention relates to improved metal/composite interfaces, particularly for risers used in offshore oil and gas production to connect a subsea oil well to a surface drilling/production facility. The invention provides a composite hoop structure configured to a bearing surface of a metal groove of metal liner over which axial fibers are laid. The composite hoop structure provides for improved transition of axial, torsional and compressive forces between composite fibers and metal surfaces of the metal liner.
|PRESSURE VESSEL WITH COMPOSITE BOSS HAVING GALVANIC CORROSION PROTECTION - The present invention is directed to a pressure vessel comprising a conductive composite boss wherein the composite boss is isolated from contact with materials with different electrical potentials so as to substantially eliminate the possibility of galvanic corrosion.
|SINGLE-LAYER COMPOSITE PRESSURE VESSEL - This invention is directed to a polymeric pressure vessel comprising a wall prepared by living polymerization such that the wall comprises a single layer of polymer having two sub-layers, an inner sub-layer that is not a composite and an outer layer that is.
|FIRE RESISTANT PRESSURE VESSEL - The present invention relates to a fire resistant pressure vessel in which the inclusion of fire resistance does add appreciably to the overall weight of the vessel over a similar vessel that is not fire resistant.
|CONSTRUCT COMPRISING METALIZED DICYCLOPENTADIENE POLYMER AND METHOD FOR PRODUCING SAME - The present invention comprises a method of forming a thin metal layer on a dicyclopentadiene polymer surface and to constructs comprising the metalized layer.
|PRESSURE VESSEL WITH COMPOSITE BOSS - This invention relates to a one-piece composite boss for use with pressure vessel used to transport compressed fluids.
|Pressure Vessel With High Tension Winding to Reduce Fatigue - This invention relates to a pressure vessel that is wrapped with a high-tension winding that prevents or ameliorates the effects of fatigue due to cyclic pressurizing and de-pressurizing of the vessel.
|Pressure Vessel Having Composite Boss With Weldable Metal Fitting - This invention relates to a pressure vessel having a one-piece polymeric composite with a weldable metal fitting such that the pressure vessel can be coupled to a source of compressed fluid by a welded connection.
