RP3.4-08 Assessing coating damage and hydrogen embrittlement risks of steel pipelines under the combined effects of hydrogen from external cathodic protection and internal hydrogen containing fuels
Cathodic protection (CP) and external coatings can prevent hydrogen from exiting the pipe wall. CP can have a similar effect as electrochemical hydrogen charging whilst external barrier coatings could trap hydrogen at the metal/soil interface and produce a backpressure for hydrogen permeating through the wall. This backpressure could also result in extensive coating damage.
This research aims at addressing these issues by assessing hydrogen embrittlement behaviour and coating damage under the combined effects of cathodic protection and external coatings with high pressure hydrogen fuels.
The scope of research will take 18 months.
