Cold-Weather XLPE Tank Failure-Mode Sequencing: From Ice Nucleation Through Wall-Thickness Gradient, Micro-Cracking, Hydrostatic Shock, and Permeation Runaway - The Five-Stage Sequence That Splits Tanks at Minus 25 Celsius
Cold-weather failure of crosslinked polyethylene (XLPE) tanks is rarely a single-event catastrophe. It is the end-state of a five-stage sequence that begins with ice nucleation on the tank wall, progr…
