If a boiler is being prepared for a hydrostatic test as part of a periodic inspection, in accordance with 46 CFR 61, which statement is true?

🔍 Key Concepts

• 46 CFR 61 requirements for hydrostatic tests on boilers • Differences in construction and circulation between fire-tube and water-tube boilers • Why specific water temperature ranges are required to prevent damage or false readings

💭 Think About

• Look up the exact wording in 46 CFR 61 about hydrostatic tests and note whether it lists different temperature ranges for fire-tube versus water-tube boilers • Think about which boiler type is more sensitive to rapid temperature changes and thermal stresses, and how that might affect the allowed temperature range • Compare the temperature spans in each choice: which option best reflects a reasonable, moderate range that avoids very cold and near-boiling water?

✅ Before You Answer

• Verify the exact temperature ranges specified in 46 CFR 61 for each boiler type • Confirm whether fire-tube and water-tube boilers have different ranges or share any overlap in required test water temperature • Check that the temperatures used are above typical cold feedwater and well below boiling to avoid thermal shock or phase change during the test

Question 1 of 27070

If a boiler is being prepared for a hydrostatic test as part of a periodic inspection, in accordance with 46 CFR 61, which statement is true?

Water-tube boilers should be filled with water from 70°F to 160°F, and fire-tube boilers should be filled with water from 70°F to 100°F.

Fire-tube boilers should be filled with water from 60°F to 170°F, and water-tube boilers should be filled with water from 60°F to 100°F.

Fire-tube boilers should be filled with water from 70°F to 160°F, and water-tube boilers should be filled with water from 70°F to 100°F.

Water-tube boilers should be filled with water from 60°F to 170°F, and fire-tube boilers should be filled with water from 60°F to 100°F.
