ADVANCED CATHODIC PROTECTION

CONCEPTS COURSE

Cathodic Protection (CP) is about to be subject to major changes in the way we interpret protection and understand its mechanism. It will change our precepts and challenge our traditional beliefs. The course is designed for experienced CP specialists and NACE Level 3 certified professionals.

The course will explain and investigate why:

We have observed cathodic protection at potentials as positive as -350mV Cu/CuSO4.

We have observed corrosion at potentials as negative as -1000mV Cu/CuSO4.

AC corrosion proceeds more rapidly the more negative the CP potential.

Larger %IR DCVG results reveal smaller defects than lower %IR DCVG results.

Our criteria for stray current corrosion may sometimes be dramatically relaxed.

Our criteria for CP interference may sometimes be dramatically relaxed.

An off potential on a coupon of +400mV Cu/CuSO4 is a good result.

Obtaining CP in soft water is problematic.

Researchers working on stray current corrosion criteria have changed their approach.

Those attending the course will also receive copies of two software programs written by Markus:

One is used in the paper “M. Büchler, A New Perspective on Cathodic Protection Criteria Promotes Discussion, Materials Performance 54, No 1, 44 (2015)”. For inputs of soil resistivity, soil type, defect size, ON potential and AC potential it draws a Pourbaix Diagram and Evans Diagram showing where the defect lies in terms of DC corrosion and CP, and provides graphs of AC & DC ON potentials and current densities indicating its AC corrosion status.

The second program replaces attenuation equations for designing CP by allowing for variations along the pipeline in the number and size of defects, pipe wall thickness and diameter, soil resistivity, CP unit locations, drain point potenials and AC potentail. The pipeline can be broken into any number of nodes to allow for such changes. The output for each node is the same as the first program plus it gives graphs of the CP unit currnet demand and ON potential along the pipeline route.

Lecturer: Markus Buchler

Markus Büchler is the Chief Executive Officer (CEO) of the Swiss Society for Corrosion Protection (SGK), Technoparkstr, Zürich, Switzerland. After joining SGK in 2000 as head of research and development, he took the position of CEO in 2006.

His field investigations and research have contributed to the understanding of corrosion of buried structures. He has a M.S. Degree in Materials Science (Dipl. Werkstoffing (ETH), April 1994) and a Ph.D. in Technical Sciences (January 1998) from the Swiss Federal Institute of Technology (ETH), Zürich, Switzerland.
