The testing pressure of storage tanks and pressure vessels designed as per Indian standard codes should be about ______________ times the design pressure?
Correct answer: A. 1.5 to 2
- A. 1.5 to 2
- B. 3 to 4
- C. 4 to 5
- D. > 5
Explanation
Hydrostatic or pressure testing is commonly carried out at about 1.5 times the design pressure to verify vessel strength and leak tightness. The range 1.5 to 2 is therefore the appropriate choice.
