Hoop and Longitudinal Stress
These stresses are used in most calculations for road and RR crossing, spans, blasting, streams, etc. before deciding on the safety of the pipe.
Live hoop and longitudinal stress must be below seam and girth weld fatigues limits. Outside force stresses must be known for proper evaluation.
