-
• API certifications are for in-service inspectors, while ASME inspectors are typically involved in manufacturing.
New pressure vessel fabrication RT, UT, hydrostatic testing, material compliance
Provides fabrication repair requirements, but doesn’t cover in-service repairs
ASME BPVC American Society of Mechanical Engineers (ASME) Authorized Inspector (AI, National Board)
NACE (AMPP)
-
Key Difference
NACE is a cross-industry standard for corrosion and coatings, which overlaps with API and ASME when dealing with material degradation
-
deals primarily with corrosion inspection and prevention, which can be integrated with API and ASME inspections
-
• NACE focuses on coatings and corrosion, making it distinct from both API and ASME.
Corrosion prevention in all industries (oil & gas, marine, construction,
Coating & corrosion control Coating thickness testing, cathodic protection testing, visual and laboratory analysis

Understanding these codes is crucial for ensuring compliance, safety, and efficiency in industrial applications. The biggest takeaway is:
-
• Use API for in-service inspection, maintenance, and repair.
