Each heat exchanger we build undergoes a rigorous, multilevel quality control review to ensure that our custom-engineered products meet the highest standards.  All units are thoroughly inspected by our quality control department and a National Board authorized inspection agency prior to shipment.

Our standard quality control package includes:

  • U1 or R forms
  • Mill test reports
  • Hydrotest certification
  • ASME code name plate rubbing
  • As-built drawing 

Aurora Industrial Machining's Quality Control Group can perform a wide variety of  in-house non-destructive examinations including:
