Curriculum Vitae

David HendrixDavid Hendrix, P.E., is the founder of The Hendrix Group, Inc., a metallurgical engineering consulting company providing materials engineering and corrosion services to the chemical, refining, oil & gas, pulp & paper, and insurance/legal communities. David has extensive experience consulting on a national and international basis in the areas of metallurgy/materials, corrosion, corrosion control documents including API 584 Integrity Operating Window development, root cause failure analysis, risk-based inspection, mechanical integrity and fitness-for-service. He has conducted several thousand failure analysis investigations concerning mechanical failures, and ambient and elevated-temperature corrosion failures. Mr. Hendrix was the lead outside consultant for the U. S. Chemical Safety and Hazard Investigation Board in investigating the corrosion-related failure of equipment in a refinery crude unit that resulted in a serious fire and has served as a testifying expert regarding mechanical integrity technology, corrosion and failure analysis.

He has worked with a variety of end-user companies, equipment manufacturers, and insurers on root-cause failure analysis, inspection and testing, and specification and selection of metals, alloys, and paints and coatings. This work has included materials selection for corrosive environments and new design applications, problem solving, and investigating the fitness-for-service of in-service equipment and components.

Mr. Hendrix graduated with honors from the University of Alabama with a bachelors degree in Metallurgical Engineering. Academic honors included deans list, and selection to Tau Beta Pi and Alpha Sigma Mu engineering honor societies. He is a registered Professional Engineer in the state of Texas and a NACE International accredited Materials Selection/Design Specialist. David holds an API 581 Risk Based Inspection certification and has been certified as a API Aboveground Storage Tank Inspector.

Mr. Hendrix has presented/authored more than thirty three papers and publications on the subjects of corrosion, failures, paints and coatings, equipment selection and performance, and risk-based inspection of process equipment. A member of numerous technical associations including NACE, ASM, and SPE, David has held many responsible positions, including Chairman of NACE International subcommittee T-5B, High-Temperature Materials Performance; 1999-2000 Chairman of the NACE International Houston Chapter; 2001-2002 Education Committee Chairman of the ASM Houston Chapter; 1999 Vice-Chairman of ASM's Gulf Coast Corrosion Control Conference (GCCCS); Vice-Chairman of the 2003 NACE Central Region Conference, and 2006-2007 Chairman of the ASM International Houston Chapter.

Prior to founding The Hendrix Group, David was Manager, Metallurgical Engineering department of Law Engineering, a multi-disciplined consulting company with offices nationwide. Responsibilities at Law included consulting on company wide materials engineering projects, business development, and technical advisor to the department's NDT group.

Mr. Hendrix also held responsible positions in Texaco, Inc.'s corporate Metallurgical Engineering department and with ARCO Chemical Co.'s corporate Specialty Engineering group. At ARCO, Mr. Hendrix was responsible for failure analysis, corrosion and materials selection for ARCO's Texas chemical plants, materials advisor on new plant construction, investigated equipment fabrication and welding problems, audited fabrication shops, and administrated ARCO's corporate equipment coatings standard.
