Abstract

Sistemas de recubrimiento que proveen resistencia a la corrosion y, opcionalmente, lubricacion, para conexiones roscadas. Las composiciones comprenden una primera composicion de recubrimiento que comprende matrices poliméricas de poliimidas o epoxis que se modifican con pequenas cantidades de un polímero que contiene fluor. En las composiciones de recubrimiento también hay presentes agentes inhibidores de la corrosion y partículas inorgánicas con una media del diámetro de aproximadamente entre 10 nm y 10 mm. Opcionalmente se agregan lubricantes solidos, que pueden incluir por lo menos uno de PTFE, HDPE, Grafito, y MoS2, para proveer al primer recubrimiento un bajo coeficiente de friccion. Los sistemas de recubrimiento pueden comprender además una segunda composicion de recubrimiento, que comprende un lubricante solido disperso dentro de una resina epoxi y un solvente. Las primera y segunda composiciones de recubrimiento se depositan por lo menos sobre una porcion de por lo menos uno de los miembros macho y hembra de las conexiones roscadas.Coating systems that provide resistance to corrosion and, optionally, lubrication, for threaded connections. The compositions comprise a first coating composition comprising polymeric matrices of polyimides or epoxies that are modified with small amounts of a fluorine-containing polymer. In the coating compositions, corrosion inhibitors and inorganic particles with an average diameter of approximately 10 nm to 10 mm are also present. Optionally, solid lubricants are added, which can include at least one of PTFE, HDPE, Graphite, and MoS2, to provide the first coating with a low coefficient of friction. The coating systems may further comprise a second coating composition, which comprises a solid lubricant dispersed within an epoxy resin and a solvent. The first and second coating compositions are deposited at least on a portion of at least one of the male and female members of the threaded connections.
