Heating cable in pipe: description and description

At the onset of cold weather, various types of pipelines are exposed to low temperatures. Frost is able not only to hold the liquid inside, but also lead to ruptures in the material of communications. To avoid long repairs and problems with water supply, sewerage and other systems, a heating cable is installed in the pipe. This device allows you to heat industrial and household pipelines, tanks. To properly select the heating cable, as well as effectively use it, you need to know the device and the features of such systems.

Wire Functions

A heating cable for heating pipes is designed for communications that lie at shallow depths, run on surfaces or on sections of buildings that are not heated. This is where the help of the presented device is required. The cable consists of heating cores, various conductive and insulating materials. A cold wire with a fork is fed to it. When the system is connected to the network, heat enters the environment. In this case, the cable can be installed both on the pipe surface and inside it.

Wire device

, необходимо понимать его устройство. Installing the heating cable in the pipe , you need to understand its device. For such purposes, a self-regulating wire is used. It looks like a ribbon cable. In it passes 2 veins, between which there is a special material. This is a polymer semiconductor matrix. It acts as the core of the cable system. A feature of this matrix is the continuity of its heating in each section. This makes it possible to cut the wire in any desired place.

Also, the semiconductor material provides a reaction for changing the heating temperature of the cable when cooling or heating the environment. And this quality is typical for each section of the system. Adjusting to the ambient temperature, the wire can not overheat. Around the veins and the matrix is insulated. It provides a dielectric strength, protection from mechanical influences. Unfavorable environmental conditions also can not damage the internal cable system.

Application area

или на ее поверхности способен уберечь коммуникации от замерзания. Heating cable inside the pipe or on its surface can protect communications from freezing. Previously, they were most often used in industrial needs. On the networks of water supply or sewerage in open areas such systems were installed. Next, the owners of private houses became interested in the products presented. Recently, more and more often a system is being purchased, which is mounted not directly on the pipe, but directly into it. This allows you to achieve a good result with minimal energy costs. The cable, which is installed inside the communications, is only applicable for water pipes with drinking or technical water.

System Benefits

имеет массу преимуществ для коммуникаций. The heating cable for the water pipe inside the pipe has a lot of advantages for communication. If there is such a heater inside the networks, the system will be durable and reliable. Pipelines in this case can be mounted above the freezing level of the soil.

When choosing a quality product, the owner of a private house can count on a long service life of the system. Condensation will not form on the pipes. Therefore, their surface will not be subject to rapid destruction. The lifetime of self-regulating wire reaches 40 years. At the same time, it consumes a minimum amount of electricity. It starts to work only when the ambient temperature drops. If it is above +15 ° C, the wire itself stops functioning. Therefore, you can forget about interruptions in the water supply system.

Installation inside the pipe

, следует помнить о некоторых особенностях этого процесса. Having decided to install the heating cable into the pipe , it is necessary to remember some features of this process. This type of installation is ideal for property owners who have already installed the water pipe. If the pipes freeze in the winter, you can purchase the presented system and install it right inside the networks. To reduce heat loss, it is necessary to equip the insulation of pipes. Its thickness is selected in accordance with the diameter of the communications. For pipes ½ or ¾ in diameter, a layer of thermal insulation of at least 20 mm is suitable. If the diameter is even greater, this proportion increases proportionally.

The better insulation is installed, the less electricity is consumed by the wire. A wide selection of special insulation for pipes is on sale . If desired, you can purchase rolls of materials. They also quite qualitatively manage to insulate communications.

Selection process

There are several features that a heating cable for heating pipes has. правильную разновидность довольно просто. Choose the right variety is quite simple. First of all, it is necessary to pay attention to the scope of the product, which the manufacturer has designated. A self-regulating wire suitable for drinking communications must have a food compliance certificate. Their insulating material is made of a polymer containing fluorine.

Next, you need to determine the required system capacity. It depends on the diameter of the pipes, the amount of heat loss, as well as the material from which the pipes are made. The greatest power that such systems possess is 50 W / m. This variety is often used for industrial communications. For commercial purposes, 15-20 W / m of system is enough for private real estate. Low-power varieties of 7-9 W / m are suitable for the narrowest, well-insulated pipelines.

Installation of the system

вполне возможно установить самостоятельно. Heating cable in the pipe is quite possible to install independently. First of all, it is necessary to prepare an epiploon. Through it, the wire will be inserted inside the pipe. If the cable goes down the system, its fixation will not be necessary. But wanting to lift it up the pipe, it is necessary to prevent slipping. To do this, they acquire a system with a rigid, reinforced shell. It will allow the wire to keep the shape.

The installation of the system is by no means carried out through the shut-off valves. First of all, the length of the communication section in which the heating element passes will be measured. This segment is marked with a special inscription. The cutting in the system is done with the help of fittings. Their threads must be closed with a tape tape. This will avoid damage to the wire by sharp edges of the fittings. Carrying out all the actions accurately, you can quickly and efficiently mount the system.

Select a manufacturer

и качество которого соотнесены идеально, производят такие бренды, как Ensto, Lavita, Raychem. Self-regulating heating cable for pipes, the price and quality of which are correlated perfectly, are produced by such brands as Ensto, Lavita, Raychem. The most popular among these systems is the first manufacturer. Ensto (Finland) produces a self-regulating wire with a power of 9 W / m. Its quality and relatively low cost make the product a sales leader. The price for 1 m of the system is 630 rubles.

Inside the pipes, cables from Lavita (South Korea) are also laid. Its cost starts at $ 200. For 1 m. But the quality of these systems is somewhat inferior to the products of the Finnish manufacturer.

The average cost is characterized by products of the company Raychem (Belgium) - from 500 rubles. For 1 m. This is a fairly high-quality system. , следует воспользоваться советами экспертов. Installing the heating cable in the pipe , you should use the advice of experts. This will allow you to select and qualitatively mount the system.
