A certain pressure vessel manufacturer avoids doing reinforcements calculations for openings by always providing a reinforcing pad extending upto double the diameter of the opening and of the same material and thickness as that of the shell wall. If area compensation is accepted as a code guideline, his approach leads to safe design____________________?
Correct answer: D. Irrespective of the shape of the vessel
- A. Only if the opening is on spherical vessel
- B. Only if the opening is on a vertical cylindrical vessel
- C. Only if the opening is on a horizontal cylindrical vessel
- D. Irrespective of the shape of the vessel
Explanation
Under the area-compensation rule, the reinforcement pad replaces the material removed by the opening, provided it has suitable material, thickness and extent. This compensation principle is not restricted to a particular vessel orientation or shape.
