In hydrostatic testing of welded pipe (for leakage, strength etc.) the ratio of minimum hydrostatic test pressure to internal design pressure is around __________________?
Correct answer: B. 1.5
- A. 0.5
- B. 1.5
- C. 2.5
- D. 3.5
Explanation
Hydrostatic tests are commonly conducted at about 1.5 times the internal design pressure, providing a safety margin for leakage and structural strength. The test pressure must remain below levels that could permanently damage the pipe.
