The DuBose National Energy Services Quality Assurance Team has successfully developed and fine tuned a comprehensive Quality Program that is second to none.

Our highly qualified and trained QA staff has a combined experience in the Nuclear, Military, and Commercial fields in excess of 200 years.

DNES has maintained an ASME Section III Accredited Quality System Certificate, manufacturing and supplying, since 1977 – the longest continuous certification in the U.S. We have expanded our accreditation to include fabrication per our N type certificates NPT Certificate Numbers N-3165, NS N-3278 and NA N-3584.

Our ongoing goals are to not only meet our customer’s needs, but to exceed their expectations.

Our Quality Program is based on:

  • ASME Section III
