Joint efficiency (J) for a seamless pipe is_______________?
Correct answer: A. 1
- A. 1
- B. 0.85
- C. 1.5
- D. < 0.5
Explanation
A seamless pipe has no welded joint whose strength must be discounted, so its joint efficiency is taken as unity. Welded construction uses a lower efficiency depending on the weld quality and inspection.
