CRN Registration for High-Pressure Reactors and Autoclaves

High-pressure chemical reactors, hydrocracking reactors, and industrial autoclaves operate at pressures and temperatures that require the most rigorous pressure vessel engineering and CRN registration. These vessels often involve Division 2 or Division 3 code approaches, FEA, and fatigue analysis.

Code Selection for High-Pressure Reactors

• ASME VIII Division 1 — up to approximately 3,000 psig for most geometries
• ASME VIII Division 2 — alternative rules for optimized wall thickness; up to about 20,000 psig
• ASME VIII Division 3 — for very high pressure above 10,000 psig

FEA and Fatigue Analysis

High-pressure reactor CRN submissions often require FEA for complex geometries and fatigue analysis for cyclic loading. Kopfkino provides integrated FEA and CRN registration services — the FEA report is part of the CRN submission package.

Frequently Asked Questions

Do mining autoclaves in BC and Ontario need CRN?

Yes. Pressure autoclaves used in gold, copper, and other mineral processing operations require CRN registration in each province of operation.
