By,identifying and addressing corrosion activity, repairing corrosion defects, and remediating the,cause, ECDA proactively seeks to prevent external corrosion defects from growing to a size that is,large enough to impact structural integrity.,ECDA as described in this standard practice is specifically intended to address buried onshore,pipelines constructed from ferrous materials. Other methods of addressing external corrosion on,onshore ferrous pipelines, such as pressure testing and in-line inspection (ILI), are not covered in,this standard but are covered in other industry standards. Users of this standard must be familiar,with all applicable pipeline safety regulations for th……
