Narrative
On 7/7/2017 a small pinhole was discovered on the bottom of a pipe girth weld connected to a 4" tee located on the sorrento dome propane pipeline manifold between the meters and the storage well. The manifold and associated pipeline was bypassed until repairs were made. Non-destructive x-ray tests determined a faulty weld was the cause of the release. Upon inspection, the cause of the leak was visually verified to be a pinhole due to an incomplete final pass at a girth weld at the 6 o'clock position of a welded tee. Nde found the base pipe material to be competent. Hc manifold is estimated to have been fabricated in the 1950s
