This standard is intended for use by corrosion control personnel, design engineers, project managers, purchasers, and construction engineers, and managers. It is applicable to underground steel pipelines in the oil and gas gathering, distribution, and transmission industries.
This standard describes methods for qualifying and controlling the quality of fusion-bonded epoxy (FBE) pipe coatings, urethane coatings, epoxy-urethanes, shrink sleeves (special applications), two-part liquid epoxies, and other properly qualified coatings (as long as the proper parameters are met in accordance with this document, e.g., polyolefin, three-layer coatings), provides guidelines for the proper application, and identifies inspection and repair techniques to achieve the best application of plant- and field-applied coating systems.
Offshore coating systems have evolved over the past 50 years to allow for restrictions in raw material use and solvent emissions. This has meant that many tried and tested systems can no longer be used. This paper describes the industry in terms of attempts to generate suitable prequalification testing scenarios which will prevent premature failures of untried new systems
NOTE: We are in the process of back adopting the ISO 15156:2020 edition to become the ANSI/NACE MR0175 standard. We will advise when the new version is available for purchase.

HISTORICAL DOCUMENT. External corrosion direct assessment (ECDA) is a structured process that is intended to improve safety by assessing and reducing the impact of external corrosion on pipeline integrity. By identifying and addressing corrosion activitiy and 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.
