Resumen

This document specifies the criteria and requirements for the in-field application of coatings, coating repair and coating rehabilitation on buried pipelines.

This document specifies:

— coating assessment (new and existing);

— removal of degraded coatings;

— surface preparation;

— on site or in situ application of external coatings.

It is applicable to petroleum or natural gas pipelines, with or without a cathodic protection system.

The pipelines could be operational during the removal, preparation and application process.

This document states qualification/testing for field contractors and site applied coatings to all of the pipeline components, including bends, tees, fittings, valves and interfaces between different coatings in soil-to-air pipeline sections.

Technical and performance characteristics of the repair and rehabilitation coating materials are referenced to ISO 21809-3.

The coating of field joints is outside the scope of this document. Field joint coatings are dealt with in ISO 21809-3.

This document excludes the application of coatings when the pipeline is immersed (submerged).
