Key Topics Covered
The exam is based on the API 936 standard, focusing on the following core areas:
1. Refractory Material Fundamentals
Candidates must understand types of monolithic refractories such as castables, gunning mixes, and ramming materials. Topics include material composition, bonding methods, curing, and properties like density, porosity, and strength.
2. Installation Methods
Exam content covers correct installation procedures using various techniques. Candidates are expected to understand formwork requirements, anchoring systems, placement methods, vibration, gunning, and patching.
3. Testing and Inspection
The ability to conduct and interpret field tests is essential. This includes sampling, flow testing, bulk density, absorption, and strength testing. Inspection of installation thickness, anchorage quality, and surface preparation is also evaluated.
4. Quality Control and Documentation
Candidates are tested on procedures for maintaining quality during installation, including acceptance criteria, inspection checklists, and post-installation documentation.
5. Safety Considerations
The exam also addresses safe handling practices, PPE usage, hazard recognition, and general job site safety for refractory work.
How to Prepare for the Exam
To pass the API-936 exam, candidates should have a strong understanding of the API 936 standard and related industrial practices. Preparation steps include:
Studying the API 936 Standard
Reading and thoroughly understanding the standard is crucial. Key sections include definitions, installation procedures, and testing requirements.
Taking a Training Course
Several training providers offer courses specifically for API-936, which cover both theoretical and practical aspects of the certification. These may include mock exams and real-world case studies.
Practicing with Sample Questions
Using practice questions and simulation tests can help reinforce knowledge and identify weak areas. Focus should be on scenario-based questions and interpreting field conditions.
Getting Hands-On Experience
Field experience in refractory installation or inspection significantly enhances understanding. Candidates should try to observe or participate in actual installations and quality control processes.
