ASME Certification Certified Companies
Authorization to fabricate pressure vessels, boilers, and nuclear components per ASME Boiler and Pressure Vessel Code.
ASME certification authorizes fabrication shops to build pressure-containing equipment to the ASME Boiler and Pressure Vessel Code (BPVC), the most widely adopted pressure equipment standard in the world. The ASME code stamp on a vessel or boiler signifies that it was designed, fabricated, inspected, and tested under a quality system meeting ASME requirements. The ASME certification process requires the fabricator to develop and submit a quality control manual to ASME, pass a comprehensive audit, demonstrate qualified welding procedures and welders per ASME Section IX, and produce a code vessel that passes inspection by an Authorized Inspector (AI) from a third-party inspection agency. The fabricator then receives authorization to apply the appropriate ASME code stamp. Key stamps include U (Section VIII Division 1 pressure vessels), U2 (Section VIII Division 2 alternative rules for higher-pressure vessels), S (Section I power boilers), and R (repairs and alterations to existing code equipment). When sourcing ASME code fabrication, verify the shop holds the specific stamp required for your equipment type and confirm their experience with your vessel's material, thickness, and complexity level.
