AMPP CP3 Technologist case studies
AMPP CP3 Technologist · Put your knowledge to work in context.
The AMPP CP3 Technologist credential is an advanced-level certification for coatings professionals who already inspect and want to be recognized for the technical judgment that sits above routine inspection: interpreting specifications, diagnosing coating failures, resolving disputes over surface preparation and application, and advising on material selection. It is aimed at experienced coatings inspectors, project coating engineers, QA/QC leads, and technical service staff in industries such as pipelines, marine, water and wastewater, and industrial facilities. The exam spans the full coatings lifecycle. Corrosion fundamentals and coating science underpin questions on surface preparation standards and methods, coating and lining material selection, and application methods and equipment. Topics on this exam: Corrosion Fundamentals and Coating Science, Surface Preparation Standards and Methods, Coating and Lining Material Types and Selection, Coating Application Methods and Equipment, Inspection, Testing, and Quality Control, Specifications, Standards, and Project Documentation, Safety, Environmental, and Regulatory Requirements, and Failure Analysis, Troubleshooting, and Remediation. The AMPP CP3 Technologist case studies are 5 cases and about 1,741 words.
1Epoxy Coating Failure on Buried Pipeline
A 12-inch diameter carbon steel pipeline is buried in clay soil with a resistivity of 1500 ohm-cm. The external coating is a fusion-bonded epoxy (FBE) applied 10 years ago.
353 words, about 2 min2Surface Preparation for Immersion Service
A carbon steel tank interior is being prepared for lining with a 100% solids epoxy. The specified surface preparation is NACE No.
357 words, about 2 min3Selecting a Coating for a Chemical Storage Tank
A new carbon steel tank will store 50% sulfuric acid at ambient temperature. The tank is 10 meters in diameter and 8 meters high.
329 words, about 2 min4Airless Spray Application Defect
A contractor is applying a zinc-rich primer using airless spray to a bridge structure. The specified DFT is 75 microns.
313 words, about 2 min5Coating Failure Due to Poor Adhesion
A newly applied epoxy coating on a concrete floor is failing by peeling after 6 months. The concrete was prepared by diamond grinding, and the moisture content was 4% when coated.
