Abstract: Methods are provided for strengthening (e.g., repairing, structurally reinforcing, etc.) a fluid-system component by installing, as a circumferential wrap or a patch, a radiation-curable composite laminate. Kits including composite repair materials and equipment for implementing the methods are also provided. Examples of fluid-system components that may be strengthened include pipework, pipelines, transmission pipelines, distribution pipelines, gathering lines, oil risers, gas risers, process piping, girth welds on pipelines or vessels, tanks, vessels, elbows, tees, flanges, and high-pressure injection lines.

Abstract: Systems, method and devices for applying a fluid composite to a carrier sheet are presented herein. An aspect of this disclosure is directed to a fluid-administering apparatus for applying a fluid composite, such as resins, epoxies, and adhesives, to a carrier sheet, such as a cloth tape. The apparatus includes a support frame with a container buttress, and a container removably received within the container buttress of the support frame. The container has a basin for holding the fluid composite, a lid covering the basin, and first and second scraping surfaces for scraping the carrier sheet. The container also has first and second slots, each of which is defined through a respective opposing side of the container. The carrier sheet passes through the first slot, traverses down into the basin through the fluid composite, slides over the first scraping surface then under the second scraping surface, and passes out through the second slot.

Abstract: A protective seal, a protective seal kit, and a method for sealing a joint region between pipes are provided. The protective seal includes a first wrap, comprising a corrosion-resistant material, wrapped around a seal region, contacting the outer surface of the pipeline assembly. A second wrap, comprising a self-adhering fiberglass composite, wraps around the first wrap. The kit includes a flexible wrap fabricated, in part, from a corrosion-resistant material, and a second flexible wrap fabricated, in part, from a fiberglass cloth impregnated with a resinous pliable-plastic material. The method includes wrapping a corrosion-resistant, inner wrap around first and second pipes such that this wrap surrounds the joint region and adheres to the pipes. A fiberglass-composite outer wrap is wrapped around the inner wrap and the first and second pipes such that the outer wrap surrounds the inner wrap and adheres to the pipes. The outer wrap is cured.

Abstract: Deformable plugs, fluid seals formed from a deformable plug, and methods for sealing a hole with a deformable plug, are provided herein. In some embodiments, the deformable plug includes a resinous composite that expands and solidifies upon exposure to a catalyst. A carrier with a compressible body configured to embed within a hole is impregnated with the resinous composite. The fluid seal can be formed from a carrier with a porous body that is compressively embedded within a hole. The carrier is impregnated with a resinous composite that expands and solidifies upon exposure to a catalyst. One or more anchors are formed from the resinous composite after being exposed to the catalyst. The anchors retain the carrier inside the hole.

Abstract: End seals, end seal kits, and methods for sealing the space between an outer casing and an inner pipe, which extends through the outer casing, are provided herein. The end seal may include a frustoconical seal member configured to seal the space at one end of the outer casing. A composite wrap covers the seal member. The kit includes a deformable sealing putty and a flexible wrap. The method includes: applying a deformable sealing putty to the outer casing and inner pipe; forming the sealing putty into a fluid tight seal, the seal having a hollow body with an annular segment disposed within the outer casing, and a frustoconical segment extending coaxially from the annular segment outside of the outer casing; wrapping a flexible fiberglass composite wrap around the frustoconical segment of the seal; and curing the fiberglass composite wrap.

Abstract: A method and kit for repairing a gas leak in a pipe containing natural gas. The natural gas repair kit includes a leak sealant, a pressure sealant, and an encapsulator. The method for repairing the gas leak includes the act of applying a leak sealant over the leak in the pipe. The method further includes the act of wrapping a pressure sealant around the pipe near the leak. The pressure sealant should enclose and contact the leak sealant. Additionally, an encapsulator should be wrapped around the pipe near the leak. The encapsulator should contact the pressure sealant and the pipe.

Abstract: A high-strength patching material made of a cloth woven from continuous filament fiberglass warp and filling yarns and impregnated between the yarns with a resinous pliabile-plastic material which hardens spontaneously upon exposure to aqueous moisture is disclosed for use in leakproof patching of pipes and other containers of fluids under elevated pressures.

Abstract: A construction material adapted for a wide variety of uses is shown, as, for example, in repairing cracks, holes and dents in the hulls and bodies of boats and land vehicles, leaks in gas and liquid conduits such as exhaust pipes and water pipes, and leaks in gas and liquid tanks and other containers; repairing fractured poles, booms, spars, antennas, and the like, and strengthening similar structures that are not fractured; patching roofs, gutters, and drainpipes; sealing leaking containers of pressurized fluids, such as air-conditioning systems, swimming pools, and hydraulic hoses; and electrically insulating all manner of articles. The product comprises a flexible web impregnated with a pliable mastic in a sealed package which maintains its contents in stable soft and pliable condition until opened, after which the web is applied to the use intended and the mastic begins to harden in place upon exposure to water, or to only the moisture in the air.
