Anti rust coating for oil pipelines

Anti rust coating for oil pipelines Methods of anti rust coating for oil pipelines (1) pipe rust rust → brush painting asbestos powder material mixing the clay piece of barbed wire wrapped insulation materials → wiping asbestos cement protective shell corrosion paint brush. (2) Pipeline brush rust rust → dressing perlite tile galvanized wire → asphalt moisture barrier protection layer → outsourcing galvanized iron brush finish. (3) pipe rust rust → up brush package superfine wool shell (or rock wool, polyurethane foam cool tile) → (aluminum foil or asphalt shingle) moisture barrier protection layer → galvanized iron finish. (4) Pipeline brush rust rust → direct injection polyurethane foam aluminum foil in the pipeline → coat protective layer of galvanized iron. Basic requirements rust layer of oil pipeline: according to the production process, the long-distance transport conditions and open dumps time, oil pipeline rust should have the following properties: good workability, safety and environmental protection, fast drying; paint bright, transparent, non-coding cover logo, do not cover the steel surface rust state; oil pipeline to withstand wind, sun, rain and other environmental conditions affect the rust layer should have good weather resistance; during handling and transport of oil pipeline there is shock, bumps and shocks and other destructive factors, rust layer should have good impact resistance; during shipping, humid Tropics job, rust layer should have good moisture resistance, salt spray resistance; cold in winter regional and summer desert areas, the ambient temperature can reach -30 ~ 60 ℃, rust layer should have good temperature variability.
