WebDec 21, 2024 · HIC Testing. Steel’s resistance to hydrogen-induced cracking in moist H2S conditions can be assessed via HIC testing. You may test your steel in a number of various ways. The GMax test and the HIC test are two examples of these assays. You can use these tests to find out how resistant the steel in your line pipe is to hydrogen-induced cracking. WebFor carbon steel products made from rolled plate, in addition to consideration of SSC resistance, HIC/SWC shall be considered (clause 8) and SOHIC and SCZ should be considered (clause 7.2.2).”. This question is in relation to NACE MR0175/ISO 15156-2 Clause 7.2.1.2. Reference: ISO 15156 Maintenance Panel Inquiry #2012-09.

WebAug 9, 2010 · Note that although HIC is independent of stress, another phenomenon of SOHIC (Stress oriented HIC) depends on stress concentration and steel needs to be stress relieved to avoid SOHIC. Appendix A of API 945 gives good information on SSC, HIC and SOHIC mechanisms and ways to counter them. Regards, Sachin
