NACE Criteria and Effective Control of External Corrosion on Pipelines

ABSTRACT

As important as cathodic protection is to external corrosion control, it may not be the

most important issue facing those concerned with preventing external corrosion.  The NACE International SP0169 document clearly states the intent of the document is to provide guidance for effective control of external corrosion.  Many seem to ignore the intent of this document and concern themselves only with cathodic protection and related criteria.  We must consider the other parts of the document and how to effectively control external corrosion with all possible methods with an understanding of how these methods work to provide expected performance.
