type of coating offers a superior dry film lubricant that produces a smooth, hard, slick surface and provides excellent corrosion and chemical resistance, often used to meet the environmental demands within the offshore oil and gas industry. Fasteners are particularly suited to PTFE coating, with its ability to provide a combination of high corrosion resistance combined with accurate torque loadings. Wellhead equipment operating under extreme conditions can also take advantage of PTFE high performance coatings, both for corrosion resistance and its load bearing and release properties. Armourcote is an engineered coating solution developed Surface Technology to inhibit corrosion and provide surface release for marine equipment. Te brand was originally established with the introduction of proprietary composite coating systems developed to overcome the inherent softness of the materials used for surface release and friction control applications. Tese composites were first developed using fluorocarbon and fluoropolymer coatings and have subsequently been extended to include
high load bearing, high temperature precision deposited dry film lubricants. Benefits include improve wear
resistance and lower friction, leading to improved abrasion resistance. Loads are taken up by the reinforcement peaks and any wear and abrasion that occurs exposes more of the fluoropolymer coating. Te peaks of reinforcement are continuously smeared with the coating, which results in a smooth wear and abrasion-resistant, low- friction finish. Where greater levels of corrosion
protection are necessary for operations in hostile and demanding environments advanced multi coat, anti-corrosion paint systems are often specified, which complement other protective surface coatings to overcome these serious situations. Te anti-corrosive qualities of epoxy paint systems make them suitable for providing marine barrier protection on subsea equipment that will be permanently immersed or in the splash- zone. Epoxy systems are also resistant to chemical attack, making them useful on equipment such as pipelines and chemical tanks. l
