Reliability

Overview

The Welding, Corrosion and Fluid Systems Engineering teams at Devon provide expert-level consultation on productivity and quality enhancement for the energy, manufacturing, fabrication, and construction industries. Typical services include hydrodynamic analysis, instrumentation evaluation, corrosion monitoring and mitigation, welding consumable and/or equipment evaluations, comparisons, demonstrations and recommendations for welding, materials testing, and correlation of wear rates to process conditions.  These services support Oil and Gas, Transmission Pipeline, Water Treatment, and suppliers to these industries. Our research combines bench-top and pilot-scale experiments, field results, and numerical simulation to study, predict, and evaluate mechanisms, parameters, and performance.

 Client Testimony

“The level of expertise and background knowledge the Welding Engineering Program provided was truly invaluable, enabling us as a company to do complete, in-depth, unbiased comparisons of the different orbital machines. The pros and cons of each machine were evenly weighted and we were able to select the best machine for our use.”
