🔍 Key Concepts

• 46 CFR requirements for non-metallic expansion joints in piping systems • Difference between scheduled periodic inspections and condition-based inspections • What triggers an internal inspection versus an external inspection

💭 Think About

• Look at the answer choices and separate those that are based on fixed time intervals from those based on the observed condition of the joint. Which pattern is more consistent with how the Coast Guard treats flexible, wear-prone components? • Think about why non-metallic expansion joints are used and how they typically fail. Would it be practical and safe to rely only on a calendar schedule, or on evidence of deterioration? • Ask yourself: in 46 CFR, when Marine Inspectors are given discretion, what kind of event or finding usually prompts them to require more intrusive inspections?

✅ Before You Answer

• Verify in 46 CFR whether internal inspections are tied to a specific time interval (e.g., 2.5 or 5 years) or to findings from external inspection. • Check if the regulation uses wording like "whenever", "if", or "when" in connection with internal inspection of non-metallic expansion joints. • Confirm whether periodic ship inspections automatically include internal inspection of these joints, or whether they normally call for external inspection first.
