发明名称 Method of creating a sleeve on tubing
摘要 A method and apparatus for the application of a sleeve upon a tubular, such as a pipe string, used in downhole applications, for example in oil and gas exploration or recovery. A mould is located around the tubular into which a composite material is injected. The material is cured at ambient temperature. Optional heating may then be applied to enhance the properties of the sleeve. The heating temperatures are well below those at which the structural integrity of the metal tubular would be compromised as regards its fitness for downhole use. Embodiments of wear protectors are illustrated for sleeves with and without wear pads.
