API 580 Risk Based Inspection Practice Test

What is a major concern related to the removal of passivation films?

1. Reduced aesthetic appeal

2. Increased equipment deterioration

3. Excessive maintenance costs

4. Lower operational efficiency

The correct answer is: Increased equipment deterioration

The removal of passivation films is primarily a concern because it can lead to increased equipment deterioration. Passivation films are thin layers that form on the surface of materials, such as stainless steel, which serve as a protective barrier against corrosion and other types of degradation. When these films are removed, the underlying metal surface becomes more vulnerable to environmental factors such as moisture, chemicals, and other corrosive agents. This exposure can accelerate corrosion rates and lead to the premature failure of equipment, increasing the likelihood of leaks or structural weaknesses over time. In contrast, the other options—reduced aesthetic appeal, excessive maintenance costs, and lower operational efficiency—while potentially relevant in certain contexts, do not directly address the most critical issue associated with the removal of passivation films. The primary focus remains on the integrity and longevity of the equipment, making increased deterioration the major concern.
