Understanding NACE RP0391: The Standard for Materials Performance in Deepwater Production
While the "NACE RP 0391 PDF" is tempting to search for free, the risk of outdated information or malware isn't worth it. Budget for the $200 purchase from AMPP—it is cheaper than replacing a corroded fly ash silo.
Engineers often make the mistake of specifying a lining based solely on its chemical compatibility, assuming it will hold up against physical wear. However, a lining that resists acid perfectly might disintegrate in a matter of weeks if exposed to a high-velocity slurry containing sand or coal. nace rp 0391 pdf
: It identifies specific risks like hydrogen grooving—localized vertical tracks caused by rising hydrogen bubbles that eat through protective films in tanks and pipes.
Before you apply your next lining system, consult the guidelines within RP 0391. The cost of the document is negligible compared to the cost of an unplanned shutdown caused by premature lining failure. However, a lining that resists acid perfectly might
: It absorbs moisture from the air, which can lead to localized dilution and severe corrosion.
A common point of confusion is how NACE RP0391 relates to (the global standard for materials in H2Scap H sub 2 cap S -containing environments). NACE MR0175/ISO 15156 focuses broadly on sour service ( H2Scap H sub 2 cap S The cost of the document is negligible compared
acid is significantly more corrosive and has a higher freezing point ( 45∘F45 raised to the composed with power F 7∘C7 raised to the composed with power C
