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.

Provided is a film forming method of a corrosion resistant film having a corrosion resistance under acidic atmosphere and a corrosion resistant member on which the corrosion resistant film is coated. The film forming method of the corrosion resistant film includes: bringing a substrate made of aluminum into contact with an aqueous solution containing sulfate ions and fluoride ions; and heating the substrate to boil the aqueous solution on a surface of the substrate and forming a corrosion resistant film containing at least oxygen, fluorine, and sulfur in the aluminum derived from the substrate on the surface of the substrate.

The subject of the present invention is a weakly corrosive and weakly coloured sulfonic acid, with an APHA colour index of less than 20, comprising chlorides and nitrites in a chloride/sulfonic acid molar ratio of between 1 ppm and 200 ppm, and a nitrite/sulfonic acid molar ratio of between 200 ppm and 6000 ppm, limits inclusive.

Methods and compositions for inhibiting corrosion of a metal product are provided. The metal product can be contacted with water that includes at least one carbonate and/or bicarbonate salt, or otherwise has components that increase the alkalinity of the water. In addition, or as an alternative, the water can include a stannous corrosion inhibitor. The water can be evaporated off of a surface of the metal product to provide a residual of the salt on the surface and/or a protective stannous film on the surface.
