NACE AMPP TR21524-2023
Commentary on Standards Development for Selection and Qualification of HSCResistant Materials in Subsea Service with Cathodic Protection
National Association of Corrosion Engineers , 02/13/2023
As a companion document to MR21525, this Technical Report provides results, review and commentary on many investigations of HSC and includes important literature data, references, background information, service experience and related standards that were utilized in the development of the AMPP MR21525. Most of the information in this Technical Report covers findings from HSC field experience and HSC data from brine/CP exposure tests or from other cathodic charging experiments. It is important to note, in the use of MR21525 and in the review of data contained herein, that HSC can also be induced from hydrogenating environments and conditions other than from just from CP exposure alone. A non-exhaustive list of such conditions is presented later in this Technical Report.
