Narrative
Enterprise employee discovered a leak on a pig trap valve. The pig trap was isolated and the valve in question was replaced. The valve was also sent to a third party for a metallurgical analysis to determine the root cause. Update 01-16-15 the metallurgical failure analysis of the failed piping components has been complete. The report states that the leak was a result of aqueous corrosion. Since the drain is a low point with zero flow, the drain is considered a dead leg where salt water and other corrosive products could collect.
