To understand the weight of this standard, one must first understand the enemy. In refineries and petrochemical plants, equipment is often exposed to sulfide-containing environments. During normal operation, high temperatures keep these sulfides stable. However, during a shutdown—when equipment cools down and is exposed to air and moisture—these sulfides react to form Polythionic Acids (PTA). Using "stabilized" grades of steel (like Type 321

: During normal operation, austenitic stainless steels develop a protective sulfide scale. As long as the system is hot and oxygen-free, it is safe. To understand the weight of this standard, one

SP0170 prescribes a multi-stage ECDA process. The classic four-step ECDA framework appears with refinements:
