Abstract

ISO 21809-1:2011 specifies requirements of plant-applied external three-layer polyethylene- and polypropylene-based coatings for corrosion protection of welded and seamless steel pipes for pipeline transportation systems in the petroleum and natural gas industries in accordance with ISO 13623.

Pipes coated in accordance with ISO 21809-1:2011 are considered suitable for further protection by means of cathodic protection.
