Overview

The Corrosion Engineering team assesses materials performance in corrosive environments and evaluates integrity management solutions for the energy industry. Specialized sour service laboratories and pilot scale flow loops provide unique facilities for industry testing, research and development.

The Corrosion Engineering team operates under the Oil and Gas sector.

Program Capabilities

  • Flow loops for evaluating corrosion-monitoring technologies and corrosion-mitigation strategies
  • Under deposit corrosion (UDC) in aqueous and hydrocarbon environments
  • Microbiologically influenced corrosion (MIC)
  • Evaluation of systems using electrochemical approaches to determine corrosion susceptibility
  • Assessing corrosion under mechanical stress to simulate environmental cracking
  • Chemical mitigation testing (e.g. inhibitors, biocides, wax dispersants, asphaltene dissolvers, etc.) for oil and aqueous systems
  • Corrosion resistance, anti-fouling properties and integrity of coatings
  • Testing according to various NACE, ISO, ASTM and CSA standards

Pilot Scale Oil Flow Loop

  • Pipeline operation simulation with controlled flow rate and temperature
  • Pipeline inspection gauge (Pig) design evaluation
  • Chemical inhibitor evaluation
  • Real time corrosion rate monitoring
  • Simulation of localized corrosion (pitting and MIC)

Sour Service Testing Facilities

  • Proof ring testing (NACE TM0177, Method A) with stresses up to 200,000 psi (based 0.252" diameter specimen) and 110ºC
  • Stirred autoclaves for sour exposure testing up to 350ºC, 345 bar (5,000 psi)
  • Autoclaves for mechanical loading in environments up to 320ºC, 200 bar (2,900 psi)
  • Rotating cage capabilities for corrosion inhibitor evaluations (ASTM G184)
