What standards must be followed when making repairs or alterations to piping systems covered by API 570?

• A. ASME B31.3 or the Code to which the piping system was built.
• B. ASME Section VIII.
• C. ISO 9001.
• D. NFPA 70 (National Electrical Code).

Answer: (A)

Repairing or altering piping systems covered by API 570 must follow the same standard that governs the piping—typically ASME B31.3 Process Piping—or the Code used when the system was originally designed and constructed. This keeps repairs within the original design expectations for pressure, materials, and testing, preserving the system’s integrity and safety. Other options don’t fit because Section VIII covers pressure vessels, ISO 9001 is a general quality management стандарт not a piping repair standard, and NFPA 70 focuses on electrical installations rather than piping standards.
