Petroleum and natural gas industries - External coatings for buried and submerged pipelines used in pipeline transportation systems - Part 2 : fusion-bonded epoxy coatings

ISO 21809-2:2007 specifies the requirements for qualification, application, testing and handling of materials for plant application of single-layer fusion-bonded epoxy (FBE) coatings applied externally for the corrosion protection of bare steel pipe for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. High-temperature coatings with a glass transition of above 120 °C or FBE primer coatings for three- or multi-layer polyethylene or polypropylene coatings are not covered by ISO 21809-2:2007. Pipes coated in accordance with ISO 21809-2:2007 are considered suitable for additional protection by means of cathodic protection.
