HISC and SSC
HISC and SSC
(OP)
During subsea pipeline design I have come across hydrogen induced stress cracking and sulphide stress cracking. i think i understand what these are, however I am unsure of the difference between them. Is SSC not caused by the hydrogen in H2S, and therefore a result of hydrogen as well? I have read that HISC affects duplex materials and can make them more susceptible when cathodic protection is applied. Is this the only difference? Thanks
