Coating compositions for coating fluid handling components, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of a fluid handling component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

The invention relates to the use of coatings of nanoscale SiO.sub.2 particles in water-carrying cooling systems to prevent abrasive corrosion and depositions as well as to a method for the production of such a coating.

A grouting material delivery and application system for coating the exterior of a collapsed liner with an even distribution of grouting material prior to insertion into a damaged conduit. The apparatus includes a wetout funnel for receiving grouting material to evenly coat the exterior of the liner. The wetout funnel includes opposite walls forming a v-shape with a slot at the bottom of the v-shape and a squeegee disposed at the slot for controlling the coating of grouting material for a uniform covering on the liner as it passes through the wetout funnel. A first ejector pipe having an inflow end and an outflow end for receiving and dispensing grouting material to coat one half of the exterior of the liner. A second ejector pipe having an inflow end and an outflow end for receiving and dispensing grouting material to coat the opposite half of the exterior of the liner.

A composition for application to a substrate is provided. The composition comprises a base component and an activator component. The base component comprises hydroxyl functional prepolymers and the activator comprises isocyanate prepolymers. The composition further comprises an amount of carbon fibre. The hydroxyl functional prepolymers are formulated to polymerise with the isocyanate prepolymers to form a polymer containing carbon fibre.

A spray coating system includes a spraying robot sized to fit within a conduit. The spraying robot includes arms that extend outward and retract inward to maintain contact with an interior surface of the conduit. The spraying robot is configured to be coupled with hoses that separately supply different fluids to the spraying robot. The spraying robot includes a spray head from which a compound formed from the fluids is sprayed onto the interior surface of the conduit. The spraying robot is configured to be pulled through the conduit and/or self-propel in the conduit to spray the compound onto the interior surface of the conduit and form a coating thereon.

An adhesive coating device for coating an inner wall surface of a workpiece provided with holes with an adhesive. A control device automatically executes an operation of applying the adhesive, the operation including positioning of the workpiece, relative positioning of a nozzle that applies the adhesive in a non-contact manner with respect to the workpiece, and moving of the nozzle, in which the adhesive is ejected and applied in an oblique direction from the nozzle to the inner wall surface of the hole, and the angle of the oblique direction is such an angle that the adhesive linearly ejected from the nozzle located outside the hole can be applied to the inner wall surface of the hole with a desired depth without interfering with an opening part of the hole.

A system and method for coating marine pipeline weld joints and wet inspection of the applied coating is provided. The coating system includes an anti-corrosion coating including a fluorescent pigment to enhance inspection of the applied coating. The system also includes a robotic crawler for traversing inside the pipe and carrying a coating apparatus and inspection apparatus respectively configured to apply the coating on the weld joints and facilitate inspection of the wet coating. The coating apparatus comprises a spraying nozzle provided on a forward end of the robotic crawler and configured to spray coating onto on the surrounding circumferential pipe surface. The inspection apparatus includes an ultraviolet radiation emitter for activating the fluorescent pigment in the coating and a camera for providing a live image feed of the coated weld joint area to an operator computing station for inspection of the applied coating.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A frozen material prevention system for preventing a freezable material in a fluid flow from freezing and accumulating frozen material in a flow path, including, a surface configured to interact with a freezable-material-miscible (FMM) liquid to retain the FMM liquid to the surface. The system can include the FMM liquid. The FMM liquid can be configured to absorb the freezable material to prevent freezing and accumulation of frozen material on the surface.

An air purging coater apparatus is disclosed for purging mixed components from the apparatus disposed in a pipeline at a pipeline site. The apparatus includes a remote-controlled apparatus for insertion within the pipeline at the pipeline site. The remote-controlled apparatus includes a drive for controllably moving the remote-controlled apparatus internally within the pipeline. A high-pressure mixing device defines a first and second inlet controllably connected to a pressurized and further pressurized source respectively of a first and second component. The high-pressure mixing device defines a high-pressure mixing chamber connected to the first and the second inlets for mixing together the first and second components. The high-pressure mixing device defines an outlet connected to the high-pressure mixing chamber for receiving a flow therethrough of the mixed components. A spin head defines an internal conical surface and a baffle so that the mixed components are applied to an inside surface of the pipeline. The high-pressure mixing device is controllably movable from an application disposition thereof to a purging disposition. In the purging disposition, the flow of the mixed components is terminated and a source of pressurized air flows into and through the first and second inlets and the high-pressure mixing chamber and the outlet for purging any residual mixed components from the high-pressure mixing device thereby avoiding any need for the use of a potentially hazardous solvent.
