ELECTROCHEMICAL MEASURING METHOD FOR STEEL MATERIAL IN AQUEOUS SOLUTION CONTAINING H2S

摘要

PURPOSE:To obtain the electrochemical measuring method for steel in aqueous solution containing H2S. CONSTITUTION:When the hydrogen permeation test or the sulfide-stress corrosion crack test of iron material is performed in an aqueous-solution environment containing H2S, the aqueous solution is made to flow at the speed of 0.5m/s or more. Thus, sulfide is not generated, and the hydrogen permeation speed is accurately measured. Or the sulfide-stress corrosion test can be performed under the constant conditions.
