Narrative
The pipe was found to have a crack 1.25 inches in length associated with two cad welded mag anode connection. The cad welds were found to be within a few inches of the long seam. It is summized that the thermite welding appeared to be a larger charge with greater heat input on the 0.203 inch w.T. Pipe which can cause liquid metal embrittlement (lme). Given the close proximity to the long seam and the proximity and geometry of the crack it is thought that heat affected zones (haz) of the erw and cad weld were interacting and were likely a contributing factor. Pipeline was originally installed in 1982 which is when we believe the cad welds were made. Repair to pipeline was by installing a five foot long type b full encirclement sleeve.
