Catastrophic tube failure engulfs boiler building in

2020-7-23 · Incident overview A severe tube rupture occurred on a high pressure steam boiler which was operating at 750 pounds per square inch shortly following a warm-up period on start-up. A catastrophic tube failure caused a release of a significant portion of the 40,000 liters of water in the boiler in approximately one minute. The inside of the entire four storey boiler building was engulfed in high
