The American Petroleum Institute’s authorized pressure vessel inspectors must have a broad knowledge base relating to maintenance, inspection, repair, and alteration of pressure vessels. The API Pressure Vessel Inspector Certification examination is designed to determine if individuals have such knowledge.

The program benefits employers and the industry as a whole by helping to:
  • improve management control of process unit operation, repair, and maintenance
  • reduce the potential for inspection delays 
  • provide a continued high level of safety through the use of highly specialized and experienced inspectors
