Thermal stress. Boilers are intended to be slowly heated to operating temperatures and pressures. A rapid change in temperature will result in stresses in the steel. These stresses can, and have, resulted in sudden cracks or fractures in the sheets, the tubes, and weld points. The sudden release of steam and water cause a massive expansion in water and steam, enough to demolish complete buildings.
