In this paper, a high-temperature and high-pressure reactor was used to simulate the corrosion of a submarine pipeline on an offshore platform by using on-site water samples and configured water samples respectively. The macro and micro analysis results show that the uniform corrosion rate obtained by using configured water and on-site water samples is basically the same, and the point corrosion rate of configured water samples is slightly higher than that of on-site water samples. The reason may be that the residual corrosion inhibitor or the presence of trace bacteria in the on-site water sample formed a protective film on the sample surface. The research results of this paper provide guidance for the next step of the sea pipe corrosion simulation test using field water or configuration water research.

摘要

In this paper, a high-temperature and high-pressure reactor was used to simulate the corrosion of a submarine pipeline on an offshore platform by using on-site water samples and configured water samples respectively. The macro and micro analysis results show that the uniform corrosion rate obtained by using configured water and on-site water samples is basically the same, and the point corrosion rate of configured water samples is slightly higher than that of on-site water samples. The reason may be that the residual corrosion inhibitor or the presence of trace bacteria in the on-site water sample formed a protective film on the sample surface. The research results of this paper provide guidance for the next step of the sea pipe corrosion simulation test using field water or configuration water research.
