Understanding how piping fails is crucial. Key mechanisms include: General and Localized Corrosion Stress Corrosion Cracking (SCC) Erosion/Corrosion Fatigue and Creep C. Repair, Alteration, and Rerating (API 570)
The protocol for executing temporary vs. permanent repairs. You must learn when fillet-welded split sleeves, enclosure boxes, or full-encirclement patches are acceptable, along with preheating and Post-Weld Heat Treatment (PWHT) exemptions.

This is the primary code. Your course material must include:
: Calculating short-term and long-term corrosion rates to determine the next inspection interval. Understanding how piping fails is crucial
Welding and Brazing Qualifications. Covers Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR).
Dedicate a block of time exclusively to calculations. Print out calculation worksheets and repeat problems until you can find minimum thickness, corrosion rates, and remaining life without looking at the solutions. permanent repairs
2.75 hours, featuring 110 questions. This tests your memory of concepts, definitions, degradation mechanisms, and responsibilities.
Learn which code takes precedence when there is a conflict (e.g., API 570 overrides ASME B31.3 for in-service piping). Conclusion
