Heating cables in the pipe: the device and the purpose of
Pipelines in Russia have always frozen, delivering a lot of inconvenience to the municipal services and residents. Repeat mistakes in the operation of central water supply systems in your personal economy somehow do not want, so smart people, before you dilute the water supply network of your private home, always think about reliable heat insulation of supply pipes or use technological devices to warm up the working environment. Think and we are with them.
Operatively warm up the water supply system( ideally - in an automatic mode) all the owners of country estates dream. Without water it is very bad, and a whole household and financial catastrophe is unfrozen to unfreeze a frozen sewage pipe. In most cases, the correct( buried) laying of external pipeline networks and the qualitatively made heat insulation are saved, sometimes the problem has to be solved promptly. In this case, the cable to heat the pipes inside becomes a panacea.
The heating cable assembly for pipes is elementary, like all genius: an ordinary electric boiler( TEN), sealed in a plastic heat-resistant shell with a coefficient of thermal conductivity ideally matched to the operating conditions. Let's consider more in detail:
- the basis: current-carrying, more often copper wires or as they like to name heating wires;
- polymer coating of wires, in the cheapest version made of PVC, but there are a lot of variations from different manufacturers;
- copper braid inner cable for heating water supply - the most functional part of the entire device;
- is an outer polymeric shell, responsible for heat transfer to freezing pipelines.
The purpose of laying a heating cable for heating pipe structures both outside and inside is also quite obvious. When the temperature of the outside air falls below -5 degrees, local freezing sites already appear in autonomous water supply networks, and severe Russian frosts can paralyze( or destroy) the entire system.
Advantages and disadvantages of the heating cable for
pipes We immediately admit that we carry out an electric cable for heating on the surface, and even more so, inside the water supply systems, we consider it an extreme measure when all other ways of protecting the water pipe from freezing have already been exhausted. Any mechanical deformation, breakdown of insulation of conductors, and communal water problems will be covered with shock electrical shocks. The main minus we have outlined, we will pass to the positive.
- correctly configured automation of the heating cable connected to the network for water supply networks frees the owners from the problems of maintaining a stable operating temperature in the water supply pipes;
- heating cable in the pipe is simple to operate: simply plug the plug into an electrical outlet and wait for the result;
- surface version requires certain installation works, but in emergency cases such winding can prevent not only freezing, but also mechanical destruction of the pipeline;
- guaranteed by the manufacturers of the internal cable for heating the coolant level of safety of the operated water pipes;
- reliable operation of cable wiring for nominal and uninterrupted operation of power grids.
Installation and installation of a heating cable
It makes sense to consider two options for the installation of water networks with similar heating elements: regular and emergency.
- In the first case, we have the frank negligence of the designers of external wiring of water pipelines that failed to provide quality, guaranteed heat insulation of the supply pipelines. Cable electric heating( inside the pipe or external stroke) becomes a forced measure.
- The second option can be attributed to the category of force majeure, when the operating conditions of the water pipe go beyond the usual climatic norms and the heating of the pipes with an internal or external electrical cable becomes the only solution to the problem.
Installation of such systems is better to be entrusted to licensed specialists, and during operation, to take into account the elementary economic factor - the consumption of the network heating cable averages 50-60 W per one running meter. Warming the plot in 50 m during one day will cost you about 900 rubles. Do not be scared, this is the marginal mode of energy consumption in arctic conditions.
