Thermal insulation methods of water pipes

The main methods of thermal insulation of water pipes water pipes, laid deep underground, are protected from exposure to low temperatures. However, not in all cases, an acceptable depth of styling is observed. The level of water pipes should be lower than the freezing level. Pipe laying depth depends on the type of soil. If the soil does not allow you to dig a sufficiently deep trench, you need to think about the insulation of the pipes. The first method is a very relevant and proven option is to create high pressure in the pipe. Water in the pipe does not freeze under pressure. In this case, it will be enough to cut a small receiver into the pipe, and pump pressure into it (about 3-5 atm.). This will be enough for the water in the pipe of the country house does not freeze throughout the winter. To resume the efficiency of the pipeline, it is necessary to struggle the stifled pressure to the usual. The second method in a very reliable way is to warm the water supply through a systematic heating of the pipe with a special cable, which is entrusted with the surface of the pipes. The depth of pipe laying here can be only 30-40 cm. This method is quite in demand and effective. Buying one meter of heating cable will cost about 350-400 rubles. As soon as the temperature decreases, the cable begins to heat up, warming up the pipes. And you can place a cable both outside the pipe and inside. The third method of pipe in the ground begins to freeze due to the inability of the soil to ensure sufficient thermal insulation with a low density. The cold penetrates into the ground, and heat, on the contrary, from the ground outside. Additional thermal insulation of the pipe will not allow you to lose heat and provide reliable protection. Thermal insulation can be performed using special heat insulators, which today have a large number, as well as certain modifications, when an air barrier is formed above the water pipe.
