: Provides procedures for applying internal coating systems to railroad tank cars used for acid transport. 5. Accessing the NACE RP 0391 PDF
Thermoplastic Linings (PE/PP)
). In low-flow or stagnant conditions, hydrogen bubbles rise vertically along the walls of storage tanks or horizontal pipes. As these bubbles travel upward, they displace the protective passive film, creating vertical channels or "grooves" in the steel. NACE RP0391 dictates design practices to minimize stagnant zones and avoid hydrogen grooving. 3. Material Selection Matrix According to NACE RP0391

Concentrated sulfuric acid behaves paradoxically compared to diluted configurations. At lower concentrations, it acts as a strong reducing acid, aggressively attacking carbon steel. However, in the , it functions as an oxidizing agent and a powerful desiccant. The Protective Iron Sulfate Shield
