Asphalt Enamel Coating
Asphalt enamel (AE) coating is a plant-applied external bitumen (asphalt) based enamel hot applied coating system to provide good corrosion protection for onshore and offshore steel line pipes and fittings.
AE is a safer and more environment friendly coating system than coal tar enamel coating, consisting of a film of primer, one or two layers of reinforcing inner wrap and a layer of outer wrap impregnated with oxidized bitumen along with various grades of asphalt enamel.
Sometimes, a solar protection (weather-resistant material) is applied to protect the coating from sunlight if the coated pipe have a long period of open air storage.
