ASME Section VIII Catalytic Reactors

Roben Mfg, Inc. fabricates catalytic reactors to ASME Section VIII Division 1 and Division 2 standards, ensuring the highest levels of pressure vessel safety and quality. Our ASME-certified manufacturing processes deliver reactor vessels that meet or exceed code requirements for materials, design, fabrication, inspection, and testing.

What Is ASME Section VIII Certification?

ASME Section VIII of the Boiler and Pressure Vessel Code establishes rules for the design, fabrication, inspection, and certification of pressure vessels. Division 1 covers standard pressure vessels using design-by-rule methodology, while Division 2 allows alternative rules using design-by-analysis for optimized vessels. ASME certification requires rigorous quality systems, qualified personnel, and authorized inspection.

Frequently Asked Questions

What is the difference between Division 1 and Division 2?

Division 1 uses design-by-rule methodology with prescribed formulas and safety factors. Division 2 allows design-by-analysis using detailed stress analysis techniques, potentially resulting in lighter, more economical vessels for high-pressure applications. Division 2 requires additional engineering and documentation.

What does ASME certification ensure?

ASME certification ensures that materials meet specified requirements, designs are properly engineered, fabrication follows qualified procedures, welders are certified, and all work is inspected by an Authorized Inspector. The U Stamp indicates compliance with all Section VIII requirements.

Do you provide National Board registration?

Yes, all ASME code vessels are registered with the National Board of Boiler and Pressure Vessel Inspectors. Registration provides a permanent record of the vessel and enables future repairs or alterations under the R Stamp program. We provide all required documentation for registration.
