Description |
The SS304 tubing of the instrument tapping line connected to nitrogen storage vessel has failed by thick-lip rupture under Hoop stress. Evidences suggest that the failure was due to presence of defects in the tubes. The defects were identified as preexisting longitudinal cracks, typical of extrusion defects. It is recommended that the entire SS304 tubing of the instrument tapping line be changed to prevent recurrence of similar failures.
