Improper material selection for concentrated sulfuric acid systems can lead to catastrophic structural failure, hazardous chemical leaks, and hydrogen gas explosions. nace rp 0391 pdf
Threaded or socket-welded piping should be avoided due to the potential for localized turbulence.
Static storage tank shells and low-velocity, large-diameter piping. Limitation: Flow velocities must remain extremely low.
Subsea structures utilize Cathodic Protection (CP) systems to prevent general corrosion. However, CP generates atomic hydrogen, which can diffuse into high-strength steels and cause Cathodic Hydrogen Embrittlement (CHE) . AMPP - The Association for Materials Protection and
