Narrative
At 10:30 on 5/16/2019, an enterprise technician noticed a diesel leak on valve 201 while making routine station check. The valve had a pinhole in the tubing which resulted in a 20 gallons leak. This tubing and other samples from shreveport terminal were used to investigate the failure. The failure analysis found two contributing factors that developed the pinhole corrosion in the tubing: excessive contamination and moisture in the fuel system and carbon steel material tubing is not suitable for this service. To prevent reoccurrence, this carbon steel tubing will be replaced by stainless steel tubing throughout the terminal, which significantly lowers the pitting rate as compared to carbon steel tubing.
