Yes, provided the resin is hydrocarbon-resistant. The standard covers FRP for hydrocarbon service, but check for specific fuel-grade additives.

Acid inlet lines inside storage tanks must extend down near the tank floor. Dropping high-concentration acid through the air space creates massive localized moisture absorption and rapid corrosion.

At concentrations between 93% and 98%, sulfuric acid acts as a powerful oxidizing agent. When carbon steel is exposed to this concentrated environment, a chemical reaction occurs that forms a protective, passivating layer of iron sulfate ( FeSO4cap F e cap S cap O sub 4 nace rp 0391 pdf

If you have been searching for the NACE RP 0391 PDF to understand the best practices for applying abrasion-resistant linings, this post breaks down what you need to know before you download, and why this standard remains a cornerstone of asset integrity.

Protocols for storage tanks, piping spools, and valves. Yes, provided the resin is hydrocarbon-resistant

NACE RP 0391 is more than just a document; it is a blueprint for extending the life of your assets in some of the harshest environments imaginable. Whether you are dealing with coal slurry, phosphate rock, or chemical effluents with high solids content, ignoring the abrasion factor can lead to catastrophic failure.

For vintage plants where the design was based on the older version, it is acceptable to cite NACE RP0391-2001, provided no more stringent requirements have been mandated by the local jurisdiction. Protocols for storage tanks, piping spools, and valves

In the world of industrial materials engineering, corrosion is the silent enemy that drains budgets, shuts down plants, and creates safety hazards. For facilities dealing with concentrated sulfuric acid ($H_2SO_4$), this enemy is particularly aggressive. This is where (now standardized as NACE SP0391 ) becomes an indispensable tool.
