Abstract: The pipe has a non-circular cross section that generally looks like that of a squashed circle. The pipe would not deform significantly from that having the squashed circle cross section under the condition in which the inside pressure is the same or less than that of the internal pressure of the pipe that carries ordinary cold tap water. The cross section of the pipe gets deformed to become rounder and larger when the water within the pipe is frozen, and the rounder and larger cross section is large enough for the pipe to contain the frozen water or ice without having any damages. The pipe is made of material such as high carbon content steel that allows the pipe to change its shape back to the pre-frozen shape as the water inside is thawed out.
