Narrative
A nipple on a 2-inch drain down valve on a tank lateral line developed a pinhole leak. The line was isolated and drained of product so the nipple could be replaced. The tank line was returned to service following the repair. The nipple was sent to a laboratory for analysis which determined the leak was caused by under deposit pitting that initiated at the id surface. The presence of water and debris caused a reduced oxygen environment under the debris which promoted pitting.
