Fundamental sources of failures: Poor assembly, service and maintenance — Lesson 1

This lesson covers the fundamental sources of failure in various systems, focusing on failures due to poor assembly, poor service conditions, and poor maintenance. It explains how improper assembly can lead to component failure, emphasizing the importance of following correct assembly procedures. The lesson also discusses how poor service conditions, such as abnormal high rate of loading, unfavorable oxidative wear, and extreme temperature conditions, can lead to premature failure. Lastly, it highlights the importance of a well-thought-out maintenance plan to prevent failure. For instance, it discusses a case study of a boiler tube failure due to poor maintenance strategy.

Key Takeaways

- Poor assembly can lead to component failure. It's crucial to follow correct assembly procedures to prevent such failures.
- Components designed for specific service conditions should not be used under different conditions. Doing so can lead to premature failure.
- A well-thought-out maintenance plan is essential to prevent failure. Regular inspection and maintenance can help detect potential failures and take corrective action.
- Case studies, such as the boiler tube failure, illustrate the importance of proper maintenance and adherence to service conditions.
