Research on the application of polyethylene anti-corrosion technology in three-layer structure of oil and gas pipelines
The main structure of the anti-corrosion layer and the anti-corrosion mechanism coating, its bottom layer is an epoxy powder. Epoxy powder is generally mainly composed of some epoxy resin curing agent, catalyst modifier, leveling agent, pigment, thixotropic agent and other materials, and then melted and extruded through a certain mixing technology, grinded and screened, and then processed to make epoxy powder. , because the epoxy resin among its components contains an epoxy group, so during the high-temperature processing of the coating, the curing agent contained in the epoxy powder and its epoxy resin An epoxy group inside will undergo a curing reaction. The result of this reaction is to produce an active group such as a light group or a unitary group, and these active groups can be combined with The metal or metal oxide combines to form an ionic bond, which allows it to firmly adhere to the metal surface.
< r /> my country’s oil and gas gathering and transportation pipelines have begun to take shape. However, some corrosive impurities appearing in pipelines will cause great corrosion to the inner walls of oil and gas pipelines, causing many pipelines to be severely corroded in less than a year or two. Severe corrosion of oil and gas pipelines will cause some accidents, and in serious cases, it will cause losses to national property and casualties. At present, the corrosion method of oil and gas pipelines has many advantages, such as easy coating and simple operation, and the cost of this method is low. At the same time, this method can also reduce the surface roughness of the inner wall of the pipeline, reduce the friction and increase the friction. Pipe life reduces energy consumption and saves costs.
