Abstract

See full text

The disclosure provides a method for establishing a hydrogen charging model for pipeline steel in an equivalent wet hydrogen sulfide environment and an application thereof, which belongs to the field of corrosion electrochemistry. The method includes the following steps: using a cathode hydrogen charging method and a wet hydrogen sulfide environment method respectively to perform hydrogen charging on each sample to be tested under different reaction conditions to obtain several first hydrogen charging samples and second hydrogen charging samples; measuring the hydrogen content of each of the first hydrogen charging sample and the second hydrogen charging sample; performing curve fitting on the variables in the two methods respectively according to the obtained hydrogen content, and the hydrogen charging model for pipeline steel in the equivalent wet hydrogen sulfide environment is obtained according to the fitting result.
