Heated pipe. Heating cables for pipe heating

House and plot

The heating systems of pipelines for protection against freezing Raychem provide protection against freezing liquids in plastic and metal pipelines, as well as maintenance of appropriate fluidity for oil. This system is nothing but cable heating of pipelines.

To heat pipelines, frostop green cables are used (10 W / m at 5 s) and Frostop Black (18 W / m at 5 s)

One cable cannot be used for heating two rooms. Due to the stitching radiation, the core is reliable over long periods of time. Let's start with the advantages of pipe heating systems. As for the prevention of freezing, you can also support pipes with warm water. We choose a warming cable in accordance with the temperature we want to get in the pipes. It is emphasized that if self-regulatory wires are used, you can abandon the circulation system hot water. It should be borne in mind financial benefits.

Hot water has the right temperature at each point of its consumption. Losses like water and energy required for its heating, less. You do not need to heat the water while you are outside the house. Installations can be installed on typical surfaces. Based on the measurement of humidity and temperature, the controller with proper coordination of the operation of the heating system saves about 75% of electricity compared to systems with only temperature measurement.

Under negative temperature ambientThe thermal insulation is not capable of independently protect the pipelines from freezing.

Sigor weather conditions may also lead to blocking fuel lines.

In cold conditions, one heat insulation cannot fully protect the drainage pipes from freezing and to compensate for heat loss, the Raychem heating cable is used, which is one of the main elements of the heating system of the pipeline electrocabel.

The accuracy of digital sensors used by the controller is much higher than that of analog sensors. Speaking about cables that are used to protect pipes from freezing, keep in mind several versions. First of all, they can be laid on the pipes and internal pipes. Use also includes pipes for maintaining temperature. sewer pipecontaining fatty substances. It should be emphasized that the wires can be used as in metal pipesand in plastic pipes. Cables are usually paved along the pipeline under the insulation layer.

Raychem pipe protection systems prevent freezing liquids in plastic and metal pipes.

Most often in winter cold, the risk of water supply controls, both domestic and home, located straight along the street or in a small depth of the ground, increases at different times or in the unheated basement.

You can choose between self-regulating and retaining cables. Self-adjustable cables are usually treated as heat sources operating in open spaces. The cable feeds on one side without the need for a regulator. In the context of properties in the form of variable resistance against the outdoor temperature, the element generates an appropriate amount of heat. On the other hand, stationary channels are considered a heat source in areas with low temperatures. Components are based on their own control in the form of a thermostat.

Heat the pipeline

Raychem's heating cables are placed and mounted by straight areas directly on pipes under thermal insulation.

Warming Cable Installation Flexibility

Heating cables can be sliced \u200b\u200bon the plots of the required length in place, which simplifies their installation.

A simple and efficient solution is a cable heating of water supply systems using a self-regulating heating cable. Ultra - modern properties Self-regulation neutralizes overheating by Raychem cables, despite a rather thick layer of thermal insulation. Thanks to this feature, the pipe heating cable will not be abrupting, working a qualitative and reliable period of time.

Please note: self-regulating pipe sets do not require the use of temperature controller. However, you can use a self-use device. It should be noted the compact dimensions of the device. More advanced models can operate with two temperature sensors, and the other - as a limiting sensor. Ease of use will definitely improve the illuminated image of a large size, informing the user about the parameters of the device. Particular attention deserves the adjustable hysteresis, which allows us to determine the accuracy of temperature measurement.

Reliability of self-regulatory cables

Heating cables do not overheat even when mounting a mustache. Thus, the system does not require maintenance.



Ease of delivery of heating cables

Raychem heating cables are supplied on a coil (you can order any needed length).

Advantages of self-regulating cables

Some controllers are designed for mounting on the dashboard. Self-regulating heating cables are popular. As a rule, they take the form of ready-to-use sets intended for direct placement with a certain length. The end is the power cord. You can also use the wires of the drum, and their lengths are adapted to specific requirements. Such solutions play an important role in the proper completion of the cord and connect to the power cord. A useful solution is a self-regulating self-regulating heating cable on the drum for use inside the pipeline.

  • frostop Green 10 W / m heating cable at 5 ° C and alternative Frostop Black 18 W / m heating cable at 5 ° C

Calculation of the length of heating cable

Heating cable is mounted on the pipe with straight areas. On short taps (up to 3 m), the heating cable is advisable to lay the loop instead of T-shaped branching. The total length of the heated pipe:

How do self-regulatory cables work? Their design is based on two parallel copper wires, which are connected to each other crosslied graphite polymer core. The resulting core is a self-regulating heating element with temperature-dependent resistance. As a result, the wires increase their heating power, when the temperature of the heated element decreases and the temperature increases with increasing temperature.

The advantages of using self-regulating cables a lot. In addition to the already mentioned ability to adjust the length according to individual requirements, a simple selection of wires and the possibility of intersection is important, so it is much easier to perform laying, especially on valves and flanges. As the ambient temperature decreases the power of the heating cable automatically increases. It is important that self-regulatory wires cannot overheat even at the intersection points, since power change occurs only in places where temperatures occur.

  • + about 0.3 m on the supply of food
  • + about 1.0 m on on T-shaped branching
  • + about 1.2 m on branching assembly for 4 chains
  • + about 1 m with additional sources of heat loss (valves more than 2 "and pipe supports without heat exchanging)
  • \u003d total required warmer cable

AT-TS-13 thermostat for cable heating reversal

These places do not affect the heating power in other places. In addition, technical isolation provides comfort for users of the water supply system. This leads, for example, to almost instantaneous water heating after the valve flow. The materials offered in this market are usually mats or coatings. Most often these are plastics, such as polyurethane, polyethylene, modified rubber, expanded polystyrene or mineral wool.

Insulation thickness depends at least from several factors. The autonomous conductor is used as a heat source in low-temperature zones. The cable that closes the plug connected directly to the network power source of 230 V is one-sided and controlled by its own built-in thermostat. It is intended for internal and outdoor use on water pipes As a heating element in antifreeze systems. The cable is attached directly to the pipe with a reinforced tape with a closely located thermostat probe against the surface of the protective element.

Selection of thermal insulation to protect pipes and heating cable

Most of the extensive supply of the market consists of a half-row polyurethane isolation. Build comfort will certainly improve automatic closure. It is based on the longitudinal cut and the mounting tape. The material is a coating of polyurethane foam with open pores. The range of isolation use includes central heating, hot and cold water in residential buildings, as well as in public and industrial buildings.

Choosing insulation based on mineral wool, there are remaining insulating products with longitudinal cuts. This product will work mainly as thermal insulation of cold and hot water pipelines, as well as systems of air conditioning, ventilation and solar water. The advantages of this type of product are, mainly the stability of the shape and strength to bend.

Freezing protection for temperatures up to - 20 ° C.

Cables for heating pipelines

Raychem pipeline heating is a freezing protection system, it protects water pipes, fire lines, sprinkler spray systems and fueling from freezing in cold winter conditions. Due to the wide range of applications, the heating cable for pipes is universal for household, industrial and commercial facilities.

Fastening the mounting pipes from heat loss, it is important to remember that the reinforcement reinforcement and bends are correctly insulated. Manufacturers, along with technical insulation, offer finished products in this regard. Therefore, you can use polyethylene insulation. It will search for arches and hard-to-reach pipelines. A special kit can also be bought with a knee in Hamburg.

Self-regulatory cables consist of two parallel copper wires connected to each other crosslied graphite polymer core. This core is a self-regulating heating element, the resistance of which depends on temperature. Thanks to this function, the wires increase their power of heating, reducing the temperature of the heated element and, accordingly, decreases with increasing temperature. Changes in power occur only in places with temperature changes and do not affect thermal power in other places, so self-regulatory cables are not subject to overheating and can even touch or intersect.

The heating system of the pipeline from freezing Raychem reduces the total installation and operation costs.

This energy-saving solution includes self-regulating cables and an automatic control device that controls the temperature and includes the system only then in those areas where it is necessary. The heating cable for pipes operates based on a special semiconductor matrix capable of changing its conductive properties depending on the temperature change. That is, it includes the system when the temperature indicators decreases and, on the contrary, turns off it when the indicators reach elevated values.

For sanitary installations there are insulating hoses made of soft polyethylene foam with closed pores. Resistance to mechanical impacts provides an external protective film. It is worth paying attention to thin-walled insulating hoses made of soft polyethylene foam and foil shell, which is resistant to rupture. The inner layer was covered with a gliding foil. Where are the hoses of this type? First of all, they will work as insulation of pipes cold water. The application also contains places where the components remain uncovered.

Heating cables to protect against freezing Frostop Green and Frostop Black are suitable for pipes and heating of pipelines from any material (copper, stainless steel, plastic, composite materials or carving pipes) without restrictions. In addition, cable for heating pipelines can be laid both inside the pipe and outside. To select the method of laying, there are certain recommendations with which specially trained specialists are familiar. It is them that it will be advisable to entrust the installation of pipe heating.

At the stage of the selection of individual components of the antifreeze system, it is important to take into account the heating power to compensate for the heat loss. You can perform self-drawing or use tables provided by manufacturers. In the process of control, special thermostats are often used. The surface temperature of the pipeline is measured at the coldest point, and then the heating circuits turn on when the temperature reaches the specified value. The thermostat is useful with the energy saving function.

When installing the electrical system responsible for protection against pipe freezing, special attention should be paid to the proper connection of the power supply chain to the heating cable. The power supply is usually based on a cold wire or a connecting outlet, which is located on the heated pipeline under insulation. Special connecting kits or junction boxes can be used to connect.

For plastic pipes, it is necessary to use the ATE-180 aluminum fastening tape. Heating cables in freezing protection systems should be closed by fastening ribbon over the entire length of the cable. The thermal conductivity coefficient of thermal insulation λ \u003d 0.035 W / (m k) or below.

Important note: Heating cables to protect against freezing with fluorine by polymer protective sheath (for example, BTV2-CT) should be used for solvent-containing, mixed and / or bitumen thermal insulation. Modern pipe heating systems must necessarily comply with all the above requirements. It is in this case that we can talk about economical, comfortable, reliable and durable work.

In winter, when negative temperatures occurs, there is a danger of freezing of water pipes. Despite the heat insulation, the frost penetrates in a layer of thermal insulation for a certain period of time, blocking the flow of water or damaging pipeline, valves or other fittings. Electric flexible hoses are ideal for this purpose. Thanks to them, we can heat both metal and plastic pipes And their fittings.

Ready heating kits with plugs

Freezing protection for cold, rainwater and sanitary pipes can be used for.

Protective protective cables

We have the opportunity to cut and pack on the construction site. They allow you to create branches. They are characterized by a changing heating capacity depending on the temperature. Heating cables increase their power in the case of a decrease in the temperature of the pipeline and decrease in the case of increasing the temperature of the pipeline. They can touch each other and intersect, there is no danger of overheating wires.
