A stuffing box is used for____________________?
Correct answer: B. Prevention of fluid leakage around moving parts
- A. Absorbing the contraction/expansion of pipeline due to temperature changes
- B. Prevention of fluid leakage around moving parts
- C. Facilitating smooth opening and closing of a valve
- D. Reducing the resistance of fluid flow
Explanation
A stuffing box surrounds a moving valve stem or shaft and uses packing to restrict leakage along the moving part. It is not primarily used to absorb pipeline thermal expansion or reduce flow resistance.
