Nathaniel G. Sutton, P.E.

Mr. Sutton has developed E²G’s abilities in accelerated creep testing, high-temperature hydrogen attack (HTHA), and high-temp material properties.  He has performed fire damage assessments, and consulted on numerous projects related to metallurgy, corrosion, materials selection,and risk-based inspection (RBI).  He has hands-on welding experience, which he has used to provide guidance on weld repairs, hot taps, and fabrication problems.  Mr. Sutton has presented at NACE/AMPP, API, and MTI conferences. 

Prior to joining E²G, Mr. Sutton worked in BP’s downstream US refineries and R&D groups.
