The device is for curing a coating substance inside a pipe. The device has a flexible shaft inside a duct, an air inlet channel within the duct, a body configured to be attached to the duct, a heat sink in connection with the body and defining a plurality of cooling channels which are in fluid connection with the air inlet channel. The device further has a plurality of light emitting devices configured to be cooled by the heat sink. The device further has an air outlet channel in fluid connection with the cooling channels of the heat sink. The air outlet channel exits the body from the same side of the body as the air inlet channel enters the body.

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.

Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters. The tool can be used manually or in an automated fashion to push and pull the paint gun and paint the interior of a pipe.

A vertical internal coating machine is taught, which may be used with bodies such as cans (2 piece, 3 piece, draw, redraw) and including cylinders, containers and any similar body. In the machine cans or similar bodies are sprayed with the star wheel in continuous motion without stopping and starting. The machine teaches that a plurality of spray guns may be provided for each pocket of the star wheel. By means of the machine an improved line layout is devised which may eliminate the need to raise the bodies immediately prior to a necker by allowing the vertical can internal coating machine and internal bake oven to be disposed on any level of the facility, upper, lower, mezzanine, etc. In green aspects, the machine may use negative pressure cabinets/hoods and positive pressure tunnels to entrain volatile organic chemicals emitted by the spray guns and coated bodies and may send these VOCs to a VOC destruction device, such as an oven.

A method of operating a pipeline or apparatus is carried out by subjecting a pretreated component of a pipeline or apparatus to cathodic protection. The pretreated component is that having surfaces previously treated with a coating of a treatment composition of a colloidal particle dispersion having inorganic nanoparticles with an average particle size from 500 nm or less that exhibit properties of Brownian motion. At least some of the inorganic nanoparticles of the treatment composition are positively charged nanoparticles. The surfaces of the pretreated component are fresh surfaces or surfaces where any residues or deposits that have been previously formed on the surfaces from prior material contact have been removed prior to being treated.
