Covers the NACE external corrosion direct assessment (ECDA) process—a process of assessing and reducing the impact of external corrosion on pipeline integrity. ECDA is a continuous improvement process providing the advantages of locating areas where defects can form in the future, not just areas where defects have already formed, thereby helping to prevent future external corrosion damage. This standard covers the four components of ECDA: Pre-Assessment, Indirect Inspections, Direct Examinations, and Post Assessment. PRINTED HARD COPIES REQUIRE A MINIMUM OF 7-10 DAYS FOR PROCESSING BEFORE SHIPPING.
Describes a method to show equivalence of other methods for measuring the level of contamination of salts on surfaces to the Bresle patch method defined by ISO 8502-9. A definition of equivalence is provided, along with information on the allowable range of variance, test methods, preparation of steel panels, data analysis, reporting, validation of test methods, and rationale for testing. This standard is an aid to those who must comply with the International Maritime Organization (IMO)’s Performance Standard for Protective Coatings (PSPC).PRINTED HARD COPIES REQUIRE A MINIMUM OF 7-10 DAYS FOR PROCESSING BEFORE SHIPPING.
This NACE Standard establishes material requirements for resistance to sulfide stress cracking (SSC) in sour refinery process environments, i.e., environments that contain wet hydrogen sulfide (H2S). It is intended to be used by refineries, equipment manufacturers, engineering contractors, and construction contractors.
