Oil and gas industries including lower carbon energy - External coatings for buried or submerged pipelines used in pipeline transportation systems - Part 3: Field joint coatings (ISO/DIS 21809-3:2025); English version prEN ISO 21809-3:2025
Abstract
This document specifies requirements for field joint coatings 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 document 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 document defines and codifies in Table 1 the different types of field joint coatings for pipelines. This document 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 document are considered suitable for further protection by means of cathodic protection.
