Which of the following repairs should be made to a badly warped boiler tube?
AI Explanation
The correct answer is C) Replace the tube with a spare, if available, or plug it.
This is the correct answer because a badly warped boiler tube should not be repaired or straightened, as that could compromise the structural integrity of the tube and potentially lead to a failure. The safest and most appropriate action is to replace the damaged tube with a spare, if one is available. If a spare is not available, the tube should be plugged to prevent further issues.
The other options are incorrect because they involve attempts to repair or straighten the warped tube, which is not recommended for a badly damaged tube. Rerolling the tube in the header (option A) or using a hydraulic jack or soft mallet to bend it (options B and D) could further damage the tube and create safety risks.
