Materials and Systems Integrity

Overview

The Corrosion and Fluid Systems Engineering teams at the Devon Research Centre provide expert-level consultation on the development, demonstration, operation, and improvement of corrosion issues and fluid flow and heat transfer systems. Typical services include hydrodynamic analysis, instrumentation evaluation, corrosion testing and mitigation, pipeline and assets integrity, process evaluations, material qualifications, and correlation of wear rates to process conditions.  These services support Oil Sand producers, Transmission Pipeline, and suppliers and service providers to these industries. Our advanced research and testing combines bench-top and pilot-scale experiments, field results, and numerical simulation to study, predict, and evaluate mechanisms, parameters, and performance.
