Petroleum and natural gas industries — External coatings for buried or submerged pipelines used in pipeline transportation systems — Part 3: Field joint coatings
ISO 21809-3:2008 specifies requirements for field joint coating of seamless or welded steel pipes for pipeline transportation systems in the petroleum and natural gas industries as defined in ISO 13623. ISO 21809-3:2008 specifies the qualification, application and testing of the corrosion protection coatings applied to steel surfaces left bare after the pipes and fittings (components) are joined by welding. ISO 21809-3:2008 does not address additional mechanical protection, thermal insulation or joint infills for concrete weight-coated pipes. ISO 21809-3:2008 defines and codifies the different types of field joint coatings for buried or submerged pipelines as presented in Table 1.
