API 936 Refractory Personnel Certification Practice Exam

API 936 Refractory Personnel Refractory linings in industrial furnaces degrade under extreme heat, chemical attack, and thermal cycling—demanding specialists who grasp material composition, installation techniques, and failure analysis. This certification tests your depth in selecting appropriate refractories for specific applications, diagnosing deterioration patterns, and executing repairs that extend equipment life. Understanding phase diagrams, bonding mechanisms, and thermal properties separates competent technicians from those who oversee costly premature failures.
