Understanding NACE SP0170: Protection Against Polythionic Acid SCC

Sulfide Stress Cracking (SSC)

In the world of oil and gas, refining, and chemical processing, material failure is not just an economic issue—it is a safety and environmental catastrophe waiting to happen. One of the most insidious threats to high-performance alloys is and Chloride Stress Corrosion Cracking (CSCC) . To combat this, engineers and integrity managers turn to a critical standard: NACE SP0170 .

Two years ago, a rival engineer had specified a standard epoxy coating under the saddle. But SP0170, buried in a non-mandatory appendix most people ignored, had a footnote: “For elevated temperature service above 400°F, mechanical isolation is preferred over coatings alone.”
