Abstract
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 method to prepare and apply a coating composition to at least a portion of a component to reduce damage to the component, the method comprising:
- combining trifunctional silane, silanol fluid, titanium dioxide, and a filler;
- mixing the trifunctional silane, the silanol fluid, the titanium dioxide, and the filler to obtain the coating composition, the trifunctional silane comprising from about 0.01 weight percent (wt. %) to about 20 wt. % of the coating composition, the silanol fluid comprising from about 40 wt. % to about 99 wt. % of the coating composition, and the filler comprising from about 0.01 wt. % to about 25 wt. % of the coating composition, one or more of the trifunctional silane, the silanol fluid, or the filler being operable to cure and form ethyl T-resin units, each of the ethyl T-resin units forming two or more bonds with one or more of other ethyl T-resin units, silanol fluid, or filler, the coating composition being operable to form a coating layer on a surface of the at least a portion of the component, and the coating layer operable to dissipate kinetic energy associated with an impact of particles on the surface of the component;
- and
- spraying one or more layers of the coating composition onto the surface of the at least a portion of the component so as to define the coating layer when coated thereon.
A method to prepare and apply a coating composition to at least a portion of a component to reduce wear damage, the method comprising:
- combining trifunctional silane, silanol fluid, titanium dioxide, and a filler;
- mixing the trifunctional silane, the silanol fluid, the titanium dioxide, and the filler to obtain the coating composition, the trifunctional silane comprising from about 0.01 weight percent (wt. %) to about 20 wt. % of the coating composition, the silanol fluid comprising from about 40 wt. % to about 99 wt. % of the coating composition, and the filler comprising from about 0.01 wt. % to about 25 wt. % of the coating composition;
- and
- applying one or more layers of the coating composition onto an interior surface of the at least a portion of the component so as to define a coating layer on the interior surface when coated thereon, the coating layer being operable to dissipate kinetic energy associated with an impact of particles on the interior surface.
A method to prepare and apply a coating composition to at least a portion of a component to reduce wear damage, the method comprising:
- combining trifunctional silane, silanol fluid, titanium dioxide, and a filler;
- mixing the trifunctional silane, the silanol fluid, the titanium dioxide, and the filler to obtain the coating composition, the coating composition operable to form a coating layer on an interior surface of the at least a portion of the component when positioned thereon, the coating layer operable to reduce wear damage to the component and operable to dissipate kinetic energy associated with an impact of particles on the interior surface of the component when the coating is positioned thereon;
- and
- applying one or more layers of the coating composition onto the interior surface of the at least a portion of the component so as to define the coating layer when coated thereon, the component comprising one or more of a goat head, a fluid end, a frac iron, an elbow, a valve, a pump impeller, a seal, a pipeline, a pipeline segment, or a pipeline pump.
A method to prepare and apply a coating composition to at least a portion of a component to reduce wear damage, the method comprising:
- applying a primer composition comprising epoxy to a surface of the at least a portion of the component so as to define a primer layer when coated thereon and cured;
- combining trifunctional silane, silanol fluid, titanium dioxide, and a filler;
- mixing the trifunctional silane, the silanol fluid, the titanium dioxide, and the filler to obtain the coating composition, the coating composition operable to form a coating layer on the primer layer when positioned thereon, the coating layer operable to reduce wear damage to the component and operable to dissipate kinetic energy associated with an impact of particles on the surface of the component when positioned thereon;
- and
- spraying one or more layers of the coating composition onto the primer layer so as to define the coating layer when coated thereon so that the component has the at least a portion coated with the primer layer and the one or more coating layers on the surface and exhibits a comparison factor indicative of an increased resistance to wear ranging from about 2 to about 30, the comparison factor being indicative of a first amount of time during which the surface of a portion of the one or more coating layers wears to a first depth divided by a second amount of time during which the surface of the portion of the component without the one or more coating layers wears to a second depth equal to the first depth.
