How to solve the problem of freezing and cracking of water pipes?

In winter, the temperature inside the water pipes is relatively low, and a thin layer of ice will form.

When water freezes, it becomes less dense, resulting in a larger volume. At the same time, the outside of the water pipe is exposed to the sun, and the temperature is relatively high.

Due to the effect of heat expansion and contraction, iron or partially plastic water pipes are malleable.

It is not good, so the water pipes are easy to freeze and crack, which not only brings considerable trouble and loss to our lives, but also affects the neighborhood in serious cases.

Winter water pipe anti-freeze solution.

1. The pipe is buried underground.

When doing home renovations, bury the water pipes underground, as the temperature underneath is slightly warmer.

2. Put a protective layer on the water pipe.

1) Rock wool for indoor buried water pipes in the north.

Insulated sleeve. 2) Outdoor water pipe anti-freezing.

Water facilities such as water pipes and faucets that are exposed to the outdoors can use cotton and linen.

Fabrics, plastic foam (insulating cotton.

EPE) is wrapped with a wrapping tape to keep warm, which can cope with low temperatures above -10. In the case of severe cold temperatures, wrap the outside with foam cotton and wrap it with a sealing film.

Note: Plastic tubing is recommended for perennial protection. You can also try using a hot water bottle, a hair dryer (PP-R tube is slightly frozen, and you can use a hair dryer.

Anti-freezing, be careful not to blow at one place when blowing, but blow up and down. The water supply pipe is thawed.

3. Increase the indoor temperature.

1) Close windows to protect from the cold.

When the weather is cold, the indoor ventilation time should not be too long. In particular, close the windows of the balcony, kitchen, bathroom and all north-facing rooms at night to ensure that the room temperature is above 0.

2) You can turn on some heating appropriately, or you can choose thicker curtains.

4. Drip anti-freezing.

Flowing water does not freeze easily.

1. First of all, if the water pipe is broken, check it yourself to see if it is broken.

2. If there is a loosening of the place where the tap pipe is connected to the faucet and affects the normal domestic water, then you can close the water valve first, and then screw the connection between the faucet and the water pipe yourself.

3. If the water pipe has not been used for a long time, or because the water pipe has been used for too long, the water pipe has begun to break from the inside to the outside, then the water pipe needs to be replaced.

4. Replace the water pipe, if you have a certain experience in replacing the water pipe, then you can replace it yourself, if you have no experience, it is recommended to ask a professional person to repair the water pipe.

5. If the water pipe is only a little ruptured in a place, resulting in water leakage, there is no need to replace the water pipe at this time, you can use black tape to wrap it, which can also solve the problem.

6. Finally, in order to reduce or avoid such problems, it is necessary to repair and maintain the water pipes regularly in life in the future, and solve the problems in time.

Keep warm and vented.

Under normal circumstances, indoor water pipes are not easy to freeze and crack. This is often the case in the case of colder winters, which is often the case in outdoor or tube well water pipes.

There are two ways to solve this problem. One is to wrap the water pipe with a layer of insulation cotton, just like putting on a layer of clothing for the water pipe, which has a warm effect and is not easy to freeze and crack. The second way is to empty the pipes.

The reason for the freezing and cracking of the water pipe is that the water inside freezes and expands, and the water pipe is swollen and cracked, and the temperature is generally low at night, so the valve can be turned off at night and the water pipe is emptied, so that it is not easy to freeze and burst.

Hope it helps.

When the water freezes at zero temperatures, the volume increases by about 9%, so it may burst through the pipe.

The general household treatment method is to close the main gate, drain the water, and keep the faucet open. This reduces the amount of water in the line and increases the space available for expansion. Also pay attention to other water-containing containers, such as toilets and toilet tanks, which should also be depleted.

It depends on the local climate and the duration of sub-zero temperatures to determine the antifreeze plan.

In a city like Shanghai, where there is no indoor heating and occasionally falls below zero, it is best to leave some drainage valves at a relatively low position of the pipeline when decorating, so that all the water in the pipe can be drained at zero temperature.

Cut off this section, attach it with a piece of pressure-resistant hose, tighten it with wire or a pipe clamp, and replace it with a new one after the winter.

If the pipe thread is not removed, the distance from the wall is too small to operate.

Roasted with fire, and welded with electric welding. If it is another material, the water pipe needs to be replaced

Get an insulated jacket on the outside of the water pipe.

The main reason why water pipes are frozen and cracked is:The temperature is low enough。"Thawing weather after snow can easily cause water supply meters to rupture and leak pipes. According to the alarm, from 9 to 11 o'clock, the water meter in the residents' homes is more frozen and cracked, and from 12 to 16 o'clock, there are more water pipe leaks.

The local temperature is low enough and there is no reliable anti-freeze measures to freeze the water inside the pipes. Water expands when it freezes. PVC pipes themselves are easy to weather, and if there is water inside, it is easy to freeze and crack in winter, which will affect the use and cause accidents.

In this regard, the emergency repair personnel have rushed to the scene in time to deal with it, and at present, the water supply has not been greatly affected. Chen Sheng, head of the customer service department of the city water company, said.

The main reasons:

When water is cold, it solidifies and increases in volume, and the low temperature makes the water pipes fragile. So instead of freezing and cracking the pipes, they swelled and cracked. The density of water is 1, the density of ice is, volume = mass density, the mass of water in the water pipe does not change, when the water becomes ice, the density also decreases, and the volume becomes larger.

When the volume is large, the water pipe bursts.

How to prevent water pipes from freezing and cracking.

In the winter in the north, the water pipes are prone to freezing and cracking, causing serious water leakage, so special attention should be paid to prevention and inspection. When changing the water pipe, be sure to wrap the pipe with insulation material, in order to prevent freezing and cracking caused by winter or bad weather in the future, the insulation material can be used with galvanized steel pipe water pipe. There are also a few tips that can also alleviate the freezing and cracking of water pipes:

1. Where there is ice in the house, it should also be wrapped in sacks and wrapped with straw ropes.

2. Anti-freezing equipment (anti-freeze hydrants, anti-freeze wooden boxes, etc.) should be installed on the faucets and water pipes outside the house.

3. In the house with water pipes, the door seams and window seams should be pasted, and the insulation in the house should be paid attention to.

4. The covered sand washed away by the flood in the rainy season should be filled before winter to prevent the soil from being too shallow and freezing to damage the water pipe.

5. Once the water pipe is frozen, do not use fire or boiling water to scald it (that will damage the water pipe and faucet due to sudden expansion), and wrap the faucet with a hot towel to help thaw it.

Because the water freezes and the water grows in volume and the pipes shrink, the cracks are protruding. Another important reason is that plastic pipes and steel pipes become brittle at low temperatures, and their pressure resistance drops dramatically, so they are easy to crack.

The water pipe is full of water before freezing, and the water pipe will not crack if there is no water or a small amount.

When the weather is too cold in winter, the temperature will be very low, when the temperature is very low, the internal molecular structure of the water pipe may change and reorganize, the intermolecular interval will be tighter, and the intermolecular repulsion will become larger.

Causes of freeze cracking.

Generally speaking, matter follows the law of thermal expansion and cold contraction, but for water, it has a certain temperature premise, for example: above 4 degrees, it is in line with the principle of thermal expansion and cold contraction, however, 4 degrees 0 degrees, due to the weakening of the force of water molecules, the molecular spacing is larger, the volume will become larger, and the ductility of the metal in winter is also weak, when the water freezes, the volume increases, and the water pipe will burst.

Prevent water pipes from bursting.

In winter, when the outside temperature is lower than freezing, we can wrap a layer of insulation material on the outer layer of the cold water pipe, so that it can play a role in heat preservation and keep the water from freezing, so as to prevent the water pipe from bursting.

Prevent the solar water heater from bursting.

Nowadays, most homes have installed solar water heaters, but what about in winter? The heating pipe of this solar water heater may be frozen and cracked, at this time, we only need to put the water in the water heater at night or in windy and snowy weather, so as to prevent the pipe from being frozen and cracked.

Generally speaking, substances follow the law of thermal expansion and cold contraction, but for water, above 4, it conforms to the law of "thermal expansion and cold contraction", but when it is below 4, water no longer conforms to the law of "thermal expansion and cold contraction", but conforms to an opposite law, called "hot contraction and cold expansion". 4 0, because the force of water molecules becomes weaker, the molecular spacing is larger, and the volume will become larger. This pattern is especially evident when the water is below 0 and ice has formed.

When the water is cold, it solidifies and increases in volume, and the low temperature makes the water pipe fragile, so it is not the water that freezes and cracks, but the water cracks due to expansion.

The density of water is 1, the density of ice is the volume mass density, the quality of the water in the water pipe does not change, when the water becomes ice, the density becomes smaller, the volume becomes larger, and the water pipe will be burst.

The main reason why the water pipe is frozen and cracked is that the burial is relatively shallow and the insulation is not good. In winter, the temperature drops below 0 degrees. It's going to freeze the pipes and burst.

In winter, the temperature decreases, the metal ductility is poor, the pressure is weak, the water molecular structure in the water pipe changes and reorganizes, the intermolecular interval is tighter, and the intermolecular repulsion force will also become larger, when the intermolecular repulsion force is greater than the molecular structure cohesion, resulting in the rupture of the water pipe.

Long-term exposure to air, thermal expansion and contraction, long-term non-replacement, the quality of the water pipe itself is not guaranteed, or the surface is exposed to external force and cracks are not repaired in time. It may cause water pipes to freeze and crack.

When water freezes, there is a process that is not thermal expansion and contraction, but cold expansion, in this process, the water pipe has to bear a huge tension, and the strength of the water pipe cannot meet the needs of the tension, and the water pipe will freeze and burst.

When the weather is too cold in winter, the temperature will be very low, when the temperature is very low, the internal molecular structure of the water pipe may change and reorganize, the intermolecular interval will be tighter, and the intermolecular repulsion will become larger.

Whose density is 1 The density of ice is Volume = Mass Density The mass of the water in the water pipe does not change, and when the water turns into ice, the density also decreases, and the volume also increases. When the volume is large, the water pipe bursts.

The density of water is greater than that of ice, and when water turns into ice, it becomes larger. Therefore, the water pipes in winter are easy to freeze and crack.

Causes of freezing and cracking: From a physical point of view, the cold winter is as low as the temperature is low, at this time, the water will slag due to the solidification phenomenon and let the ice, the mass before and after solidification remains unchanged, and the density of ice is smaller than that of water, so the volume will become larger after freezing, so the water pipe can be frozen and cracked.

In winter, the practice of avoiding the rupture of the water pipe can be insulated by exposing the water pipe and faucet on the ground, such as using a wooden square bucket to cover the faucet, filling it with sawdust, exposing the faucet, and adding a wooden cover can not freeze, it is best to add a main valve at the starting point of the exposed water pipe, once the faucet is frozen, the main valve can be closed, or the main valve can be closed when going out for a long time to prevent water leakage when the faucet is frozen.

1. Do not twist the frozen water pipe, do not use pliers and other tools to start hard, and do not use fire or boiling water to pour it directly, otherwise it is easy to damage the faucet and cause the pipe or water meter to burst. The correct way to do this is to wrap the faucet in a towel and pour warm water along the faucet to thaw it down the pipe, or use a hair dryer to blow the faucet.

2. The freezing of indoor pipes can be solved by increasing room temperature.

Precautions for water pipe freezing:

1. Protect the billing water meter, remove the water in the water meter well, and wrap the water meter in the meter well and the opening cavity of the front and rear water pipes with thermal insulation materials, exposing the dial for easy inspection.

2. Close the doors and windows at night to ensure that the indoor temperature is above 0. In case of severe cold weather (below -3), in order to keep the faucet from freezing, the most effective way is to unscrew the faucet slightly after using the water, keep the drip or line flow state, and ensure the flow of tap water in the water pipe.

Yes. Ice is less dense than water, and when water freezes, it expands in volume and increases in volume by 10%. After the water freezes, the volume expands, and the pressure generated cannot be transferred through the pipe, so it must break through the weakest part of the water pipe's pressure resistance, release the pressure, and cause the water pipe to burst.

Water pipes will freeze and burst. The density of ice is less than that of water, and when the water is formed into a leakage of ice, the volume expands and the volume increases by 10%. After the water pipe freezes, the water pipe becomes a closed container, after the water freezes, the volume expands, and the pressure generated cannot be transferred through the pipe, and it is bound to break through the weakest part of the water pipe's compression, release the pressure, and cause the water pipe to burst.
