Narrative
A magellan maintenance crew was welding a 2-inch tor onto the #6-12 pipeline at albany junction in preparation to launching a pig when a nearby 1/2 inch ball valve associated with the relief tubing for a mainline valve failed. The line was not running at the time and the release was quickly controlled. The downstream rov was already closed when the release occurred so the pressure receded in a short amount of time and a plug was quickly placed into the fitting. The ball valve that failed was approximately 20 feet away from the tor being installed. The failed ball valve was sent to a laboratory for analysis. The lab concluded the valve separation resulted from a shear overloading of the threads, most likely due to temperature and pressure build-up from electrical resistance heating during welding of the tor.
