API 570 provides three methods to determine probable corrosion rates for new installations or service changes. Which API 570 reference is cited for this method?

• A. API 570 section 5.4
• B. API 570 appendix C
• C. API 570 section 9.3
• D. API 570 paragraph 7.1.2

Answer: (D)

Understanding how to estimate corrosion rates when there is no operating history is essential for planning new installations or service changes. API 570 addresses this scenario in a specific place, guiding how to determine probable corrosion rates using established approaches, especially when you’re starting from little to no performance data. This reference provides the exact method to rely on for these estimates, which is why it’s the correct citation for this item. The other sections or appendices point to different topics within API 570 and do not provide this particular guidance on estimating corrosion rates for new or modified service.
