Being certified by the National Board Inspection Code (NBIC) is a key aspect of our company. Having a NBIC “R-Stamp” allows us the flexibility to serve our clients in repairing and/or altering pressure vessels. All of our work is performed under ASME Section VIII, Div. 1 and individually verified by an Authorized Inspector (AI). Maddox Industrial Group travels across the United States providing a variety of essential services to our clients in pressure vessel installations, inspections, repairs and alterations.
