Abstract

The paper deals with damage mechanisms affecting the piping and piping elements during working life of the well collector as an integral part of the upstream plant. An initiated crack has propagated in the vertical piping elbow and caused leakage. The damaged elbow has a sensitive cut, and a new elbow is welded onto the pipe by GTAW and SMAW processes. Necessary NDE was performed after repair welding activities showing that remediation of the line is properly conducted. The line is successfully put into service.

Keywords: piping elbow, cracks, manifold, repair
