ANSI - NACE TM 0284 - 2011, Evaluation of Pipeline and Pressure Vessel Steels for Resistance to Hydrogen-Induced Cracking

National Association of Corrosion Engineers (NACE) International, Houston, TX. 2011. 23p. ISBN: 1-57590-163-3Provides a standard set of test conditions for consistent evaluation of pipeline and pressure vessel steels and compares test results from different laboratories pertaining to the results of the absorption of hydrogen generated by corrosion of steel in wet H2S. Describes two test solutions, Solution A and Solution B, and includes special procedures for testing small-diameter, thin-wall, electric-resistance welded and seamless line pipe. Test is intended to evaluate resistance to hydrogen-induced (stepwise) cracking only, and not other adverse effects of sour environments such as sulfide stress cracking, pitting, or weight loss from corrosion. Complements NACE MR0175/ISO 15156.This standard establishes a test method for evaluating the resistance of pipeline and pressure vessel plate steels to HIC caused by hydrogen absorption from aqueous sulfide corrosion
