Water pipes some times burst during severe wintres in cold countries?
water expands on freezing

When water freezes it expands, as opposed to practically all other liquids. (For this reason ice fortunately forms on the TOP of ponds and lakes.) The expansion causes pressur…e to build up that could eventually burst the pipe. However, most water pipes burst because, as the ice builds up in the direction of the pipe, the water pressure continues to build up downstream from the growing volume of ice, that is between the ice and the faucet's. (Water pressure does not appreciably increase upstream as there is much more water on this side.) This enormous buildup of pressure can eventually cause the strongest of pipes to burst. It is a good idea to leave a faucet dripping if the pipe leading to it is in danger of freezing. Not only does this significantly reduce the chance of the water freezing in the pipe, but it keeps the water pressure from building up to dangerous levels that can cause bursting.
WHY PIPES BURST Surprisingly, ice forming in a pipe does not typically cause a break where the ice blockage occurs. It's not the radial expansion of ice against the wall of …the pipe that causes the break. Instead, following a complete ice blockage in a pipe, continued freezing and expansion inside the pipe cause trapped water's pressure to increase downstream - between the ice blockage and a closed faucet for example at the end. It's this increase in water pressure, literally thousands of pounds of pressure, that leads to pipe failure. In other words, the pipe bursts where little or no ice has formed.
because the water inside the pipes freezes which causes ice to be created, which then expands and causes the pipe to burst
Generally the same materials are used for pipes in moderately cold contries, they are just buried deaper in the ground so that they are below the surface layer that freezes.. … In really extreme situations insulation can be used but this only works if the water flows all the time. Any pipe will freeze if the temperature around it is below freezing and the water sits there for long enough no matter how good the insulation, in these situations heater elements can be run along the pipes but this is expensive, both for installation and running energy costs.
Ice forms in the pipes. When water freezes it expands a little bit! In water pipes it sometimes expands just enough to split the pipe. The reason why water pipes sometimes …burst in winter is because water pipes are full of water and in the winter the air is very cold, sometimes in the UK even 2 or 3 degrees celcius. Because the air is so cold, and the air is surrounding the water pipes During the winter, the cold air is surrounding the pipes, which has water. The air turns the water inside the pipes to ice. When water freezes, it expandes. The frozen water expanded just enough to cause the pipe to burst.
Water expands when frozen, Metal contracts when frozen, somethings gotta give.
They freeze. Water expands when it freezes and the pipe breaks.
the pipes were metal and metal rusts when water is on it
turn off main tap at building entry point
Becuase when water freezes, it expands and burst the pipe from the inside.
Because ice (solid water) has a higher volume than liquid water. As water freezes the molecules stick together with hydrogen bonds but with large gaps in between thus the vo…lume increases and expands
Water pipes tend to fracture or crack when an earthquake occurs rather than burst (something bursts when the pressure applied to it's internal surface gets to large and exceed…s the strength of the material is is formed from - a bit like if you force to much air into a balloon). Pipes tend to fracture because the seismic waves make the ground move up and down, backwards and forwards and side to side. This causes the pipe to be bent in differing directions as well as being squashed and stretched. These compression, shear tensile and torsion force will, if they are large enough, create stresses within the pipe wall that are large enough to break it, forming a crack.

Because the water expands! . Water when it freezes - - expands. Therefore water in pipes will split the pipes; water in a glass will break the glass; water in plastic jugs wi…ll disform the jugs. .
Water in the pipes turn to ice and it will expand till it breaks. Always let your pipes run a little water at all times when it is cold.
