Resumen

ϲʿ 21809-3:2016 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 ϲʿ 13623. This part of ϲʿ 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.

ϲʿ 21809-3:2016 defines and codifies in Table 1 the different types of field joint coatings for pipelines.

ϲʿ 21809-3:2016 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 ϲʿ 21809 are considered suitable for further protection by means of cathodic protection.
