Coal Silo Failures Reveal the Need for NDE Inspection

In July 2016, a coal silo collapsed at an Indiana power plant. The root cause was identified as cracking of the cone-to-skirt weld. Warnings to inspect this vulnerable weld were published widely in conference proceedings and trade journal articles. Nevertheless, coal silos continue to fail at an alarming rate (Figure 1), which suggests that the […]
