Practical applications of hydrogen permeation monitoring and modeling are presented. Applications discussed are effectiveness of HVOF metalizing on preventing permeation and monitoring sulfide scale stability. Use of a simple modeling program to determine a diffusion coefficient for seamless pipe during full ring testing and to determine sample soak duration when running hydrogen charged mechanical tests will be presented.
