Multiphase Flow Internal Corrosion Direct Assessment (MP-ICDA) Methodology for Pipelines

This standard describes the NACE International internal corrosion direct assessment (ICDA) process for multiphase flow pipeline systems. Intended to serve as a guide for applying the MP-ICDA process to these types of pipeline systems, this standard outlines a methodology to assess pipeline integrity because of the threat of internal corrosion. This standard applies to both onshore and offshore pipelines containing CO₂, H₂S, and O₂. Included in this standard are several figures detailing the steps in the MP-ICDA assessment process and tables containing data and selection criteria. There are also three appendices for additional information.
