To avoid PTA SCC—caused by reaction between sulfur, oxygen, and water—the standard recommends: Alkaline Washing:

) reacts with the existing iron sulfide scales. This chemical reaction produces polythionic acids ( H2SxO6cap H sub 2 cap S sub x cap O sub 6 , where x typically ranges from 3 to 6). 3. Tensile Stress

Successful execution of NACE SP0170 protocols requires close coordination between operations, safety, and quality control teams.
