The ISO 21809-1 standard mainly targets external coatings for buried or underwater pipelines in the petroleum and natural gas industry pipeline transportation system, especially polyolefin coatings (3PE and 3PP). Taking the ISO 21809-1:2018 version as an example, according to ISO 13623, this document specifies the corrosion protection requirements for factory applied three-layer polyethylene and polypropylene coatings on welded and seamless steel pipes in pipeline transportation systems for the petroleum and natural gas industry. And the pipeline coated according to this document is considered suitable for further protection through cathodic protection.
