MERL provides Reclamation with corrosion engineering and technology services:

  • Cathodic protection design, testing, troubleshooting, and repair.

  • Corrosion-related inspection during and after construction and whenever problems arise.  This includes inspection of pipelines and tanks, evaluation of efficacy of cathodic protection systems, and fiber reinforced polymer repairs.

  • Corrosion testing  and monitoring in field and lab settings including salt fog, immersion, cathodic disbondment, electro impedance spectroscopy (EIS), and coupon testing per ASTM standards.

  • Applied research facilities for assessment of new materials, corrosion mitigation methods, and corrosion and degradation issues related to Reclamation materials in a variety of environments and water chemistries.

  • Forensic analysis and failure analysis of metal parts and coatings, metallographic examination, analysis of fracture surfaces, examination using microscopy and X-Ray diffraction.

  • Materials selection for metals and non-metals.

Assistance can be provided for the following structures (but not limited to):

  • Pipelines
  • Storage Tanks
  • Pressure Vessels
  • Canals
  • Dams
  • Pumps
  • Gates
  • Trashracks

Corrosion and Coatings School:

Corrosion and Coatings School is a 3-day course offered by MERL.  This course will familiarize participants with the issues relating to corrosion of metal and corrosion protection including how corrosion occurs and methods to minimize and prevent corrosion to infrastructure, protective coatings, cathodic protection, new technologies; and inspection and repair techniques.  The course will also provide hands-on experience to participants.  Contact any group member for further information.
