Assessment (SCC) Management

MC140 MasterClass Series/ASME STANDARDS COURSE MC141 MasterClass Series/ASME STANDARDS COURSE
This two-day MasterClass provides a broad overview of analysis methods This two-day MasterClass is intended for engineers interested in learning
for defects in pipeline. The course begins with a summary of important more about SCC, conducting SCC integrity assessments, and managing
material properties and a review of integrity assessment methods for the results of such assessments. Prerequisites are two to four years of
pipeline defects. Analysis methods for corrosion are covered, including experience related to pipeline integrity management and/or involvement
