The alkaline wash neutralizes any polythionic acid as soon as it forms. nace sp0170 pdf

: It emphasizes the importance of regular maintenance and monitoring of CP systems to ensure their continued effectiveness.

The NACE SP0170 standard provides structured methodologies to interrupt the PTA-SCC triangle, primarily focusing on neutralizing or isolating the corrosive environment during shutdowns. 1. Alkaline Washing (Soda Ash Solutions) To get the actual details of SP0170, downloading

Residual stresses from welding, cold forming, or operational thermal stresses provide the mechanical energy required to propagate cracks along the weakened, chromium-depleted grain boundaries.

When these three factors intersect, intergranular cracking can propagate through the metal walls in a matter of hours, leading to catastrophic leaks upon startup. Core Mitigation Strategies in NACE SP0170 The alkaline wash neutralizes any polythionic acid as

NACE SP0170-2018 focuses on the complete "shutdown" period, which it defines as encompassing not only the actual downtime but also the periods required for safely shutting down and starting up the equipment . The standard outlines three primary mitigation methods to prevent PTA SCC.
