Resumen:
This part of ISO 21809 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. This part of ISO 21809 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.This part of ISO 21809 does not address additional mechanical protection, thermal insulation or joint infills for concrete weight-coated pipes.This part of ISO 21809 defines and codifies the different types of field joint coatings for buried or submerged pipelines as presented in Table 1. NOTE Pipes coated in accordance with this part of ISO 21809 are considered suitable for further protection by means of cathodic protection.
