WebJul 1, 1999 · Abstract. The SOHIC phenomenon and the newly proposed test method for evaluation of SOHIC resistance are briefly reviewed in context with laboratory and in-service behavior of line pipe steels in order to explain the apparent discrepancy in SOHIC resistance between modern, clean steels and older, more dirty steels. Conference: Corrosion … WebSOHIC can have a greater effect on serviceability than HIC because it effectively reduces load carrying capabilities to a greater degree. The inspection requires characterization of …
