The wall thickness for a large high pressure pipeline is determined by the consideration of the____________________?
Correct answer: B. Circumferential pipe-wall tension
- A. Axial tensile stress in the pipe
- B. Circumferential pipe-wall tension
- C. Forces exerted by static and dynamic action at bends
- D. Temperature stresses
Explanation
Internal pressure produces hoop stress approximately twice the longitudinal stress in a thin cylindrical pipe, so circumferential wall tension normally governs the required thickness. Axial and thermal effects may still require separate checks.
