Does the density of ice vary at different temperatures?

Does the density of ice vary at different temperatures? How much pressure does the expansion that occurs when water turns into ice exert on pipes, and can this pressure be enough to rupture 304 pipes?

When water turns into ice in a confined space, the force generated is extremely large. Whether the container will be ruptured depends on factors such as its material, structure, and strength; it cannot be determined simply based on assumptions. If it was known in advance that the water in the container would freeze due to low temperatures, why weren’t preventive measures taken ahead of time? This is a matter of human management and systems, not a problem with water turning into ice or the material of the container.
The crystal structure of ice varies at different temperatures, resulting in different densities. Water has a high degree of expansion when it freezes. In typical engineering designs, if a space is tightly sealed and the pipe materials are not strong enough to withstand such expansion, the pipes will burst. In areas where temperatures are below freezing in winter, heating is generally necessary.
