🔍 Key Concepts

• Waterside grooving as a specific type of tube corrosion in boilers • Typical location and pattern of waterside vs fireside corrosion on boiler tubes • How flow patterns and water level affect where internal corrosion damage appears

💭 Think About

• Think about whether waterside grooving is related to the water side, the gas side, or both, and how that would affect where and how you could see it during an inspection. • Consider which answer choices describe a location or pattern that would make early visual detection especially hard before any leakage is obvious. • Ask yourself: does this damage require special testing to even suspect it’s present, or is it more about its physical position and orientation in the boiler?

✅ Before You Answer

• Verify which option actually matches the known typical location/pattern of waterside grooving on boiler tubes. • Check whether any option is clearly describing fireside conditions, which would not match a purely waterside corrosion mechanism. • Confirm whether waterside grooving is usually associated with tube bends, horizontal runs, or a specific drum connection, and how that influences detectability.
