Case history: A steam line rupture at Tennessee Eastman division

At approximately 1:07 PM on November 3, 1998, a 12'' branch 600 psig steam line on a pipe bridge near the center of the Tennessee Eastman Division (TED) plant ruptured catastrophically. A 36'' long section of the line upstream of a decommissioned venturi flow meter failed, resulting in a major steam leak. The leak led to the loss of 600 psig header pressure throughout the plant, resulting in the shutdown of all steam generation equipment, and the loss of production throughout most of the TED facility for a period of 5‐7 days.
