Petroleum and natural gas industries - External coatings for buried or submerged pipelines used in pipeline transportation systems - Part 3: Field joint coatings (ISO 21809-3:2016)
N EN ISO 21809-3
Annotation
This part of ISO 21809 specifies requirements for field joint coating of seamless or welded steel pipes for buried and submerged sections of pipeline transportation systems used in the petroleum, petrochemical and natural gas industries as defined in ISO 13623. This part of ISO 21809 specifies the qualification, application and testing of the corrosion protection coatings applied to steel surfaces left bare after the joining of pipes and fittings (components) by welding.
This part of ISO 21809 defines and codifies in Table 1 the different types of field joint coatings for pipelines.
This part of ISO 21809 does not address requirements for additional mechanical protection, for thermal insulation or for joint infills of concrete weight-coated pipes.
NOTE Field joints of pipes and fittings coated in accordance with this part of ISO 21809 are considered suitable for further protection by means of cathodic protection.

Нефтяная промышленность и газовые отрасли промышленности - Внешние покрытия для проложенных под землей или затопленных трубопроводов, используемых в системах транспортировки трубопровода - Часть 3: покрытия Монтажного шва (21809-3:2016 ISO)
Эта часть ISO 21809 определяет требования для покрытия монтажного шва бесшовных стальных труб или сварных стальных труб для проложенных под землей и затопленных разделов систем транспортировки трубопровода, используемых в нефти, нефтехимические и газовые отрасли промышленности, как определено в ISO 13623. Эта часть ISO 21809 определяет квалификацию, применение и тестирование покрытий защиты от коррозии относились к стальным поверхностям, оставленным голыми после присоединения труб и деталей (компоненты) путем сварки.
