How to warm the pipe?
Many had to deal with frozen pipes. How to warm the pipe, tell our article.
Water in pipes can freeze when the pipeline is laid without proper consideration of the type of soil and specifically the depth of its freezing.
In some cases, the water pipe freezes when it rusted inside and in some areas rust particles accumulate, which prevent the water from passing through the pipe quickly. In order to prevent such freezing, it is necessary to lay the pipe at a depth of approximately 2 meters and you will not have to think about how to heat the pipe in the ground. In the case when it is impossible to do, it is necessary to use a special heating cable. To avoid freezing of the water pipe, it is also necessary to eliminate all its leakage.
A sewer pipe can freeze when its slope towards the cesspool is small or when cold water constantly flows from the toilet bowl or faucet and does not pass a large amount of warm water, which helps to remove the icing.Small drains of cold water can thoroughly freeze such a sewer pipe, and if it is also metal, so much the more.
The sewer pipe is heated by pouring hot water or a solution of water with salt into the sewage system.
Methods for heating pipes
The water pipe will freeze when the soil around this pipe becomes negative, that is, it freezes completely. If you warm the pipe, you will still not be able to heat the soil layers.
Here's how to warm a frozen pipe:
- Wrap the pipe with rags or foam and periodically pour boiling water on it. This method is the most affordable, but can only be used indoors. If the frozen pipe (including metal-plastic) is under the ground, then such boiling water with its boiling water can be delayed for 11-13 hours.
- You can heat a plumbing or sewer pipe with the help of special equipment that is used for preventive washing of these pipes - a hydrodynamic installation that supplies hot water with a temperature of 150 ° C through a high-pressure hose with a capacity of 90-100 atmospheres.Such a unit operates from an electrical network of 380 V and a minimum power of 7 kW, and the water boiler is powered by diesel fuel. It is possible to heat such a pipe with the help of water at room temperature, but this method is ineffective.
- You can also heat the pipe with the help of hot air, which can be produced, for example, by a building dryer, various heaters that are equipped with fans. But how to warm the plastic pipe? It should be remembered that if the heating is incorrectly calculated, then the pipe can be melted. This method takes time from 2 to 10 hours.
- You can also wind the pipe in a spiral with wires that are used in a floor heating system and connect the wires to the network. Such heating of plastic pipe takes up to 4 hours. This method is not suitable for heating underground pipes.
Underground water supply
It is worth remembering that the water in the underground water supply can freeze even when entering your house, for example, in the basement or basement, because concrete can freeze faster than the soil. To avoid this, it is possible to place a pipe in a sleeve, that is, a pipe with a large diameter, in the places where such a pipe passes through the wall, and fill the voids formed between these pipes with polyurethane foam.
Underground plumbing can also be protected from freezing with a merilone, isover or glass wool. You can also cut strips of foam, glue the box from these strips and put it on the pipe. You can fill the cavity of the box with polyurethane foam.
Now you know how to warm the pipe without calling emergency services!
