Anti rust coating for oil pipelines

Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical or electrochemical corrosion reaction of steel pipe.

Methods of anti rust coating for oil pipelines

1PE, 1PP layer

2PE, 2PP layer

3PE, 3PP layer

(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.
