eLearning

• 3 months online access

Upon successful completion of this course, delegates shall be able to;

1. Explain the working principles of bolted flange assemblies and their role in maintaining joint integrity.
2. Identify and describe the various types of flanges, including sealing faces and surface finishes, and determine their suitability for specific service conditions in accordance with relevant ASME standards.
3. Understand flange ratings, specifications, and component sizing requirements.
4. Describe the types, materials, and properties of gaskets (non-metallic, semi-metallic, metallic) and their application in different operating environments.
5. Describe bolt types, materials, and specifications (including ASTM A193), as well as thread design and terminology per ASME B16.5 and related standards.
6. Explain the principles of flange assembly, including the effects of friction, lubrication, alignment, and the role of washers.
7. Compare bolt tightening methods and sequencing, and explain the correct application of hot bolting and half-bolting procedures.
8. Understand the pressure testing requirements for flanged joints and the differences between hydrostatic, pneumatic, and other test types.
9. Apply inspection acceptance criteria for flange faces, bolts, and gaskets, including damage assessment and in-service evaluation per ASME PCC-1, ASME PCC-2 and other references.
10. Identify common causes of flange leakage and apply troubleshooting techniques to prevent recurrence, considering gasket behaviour under load and thermal cycling.
11. Demonstrate understanding of key requirements from the API BFJI reference publications to support closed-book exam performance.
12. Build exam readiness through practice mock exams, applying knowledge to US-style multiple-choice questions.
