Preparation of constituent elements for heating pipes.

The appearance of this product is an elastic heating element. There are two types of heating cables:

  • Having a constant resistance( resistive).The most popular due to the low price. The principle of operation is that the conductor( metal or alloy) generates heat due to high resistance.
  • Zone resistive. It is usually more expensive. The price is due to the fact that it is more quality and reliable. Types of heating cables.

In order to independently design and install cable heating pipes, it is necessary to provide all the nuances:

  • Calculate the length of the wire that will go to the winding, given the diameter of the pipes;
  • Take into account the depth at which the system is laid;
  • Length of the plumbing to be heated;
  • Selects the cable power, which directly depends on the thickness of the pipe walls. Types of heating cables.

How to prepare the cable for installation and operation.

Before starting work, read the manufacturer's recommendations carefully. The connection process itself should be done by a skilled worker who specializes in this type of work. The wire must be grounded in accordance with the regulations in force.

It is strictly forbidden to shorten, stretch and expose to other mechanical influences.

Work should be carried out in the warm season, as the influence of low temperatures leads to the risk of damage to the cable. Types of heating cables.

The piping subjected to the winding must be cleaned of debris, dirt and not be mechanically damaged.

You can not use ordinary adhesive tape as an adhesive tape, as this will lead to overheating of the cable and, accordingly, to its damage.

Ways of laying the cable in the heating system.

There are two methods of laying the heating cable, which are used in everyday life for the heating of sewer pipes:

  • Over the pipe;
  • Inside the pipe.

There are also several options for laying:

  • Laying is carried out linearly along the entire length of the pipeline in several parallel rows, the number of which depends on the required capacity;
  • Winding the wire on the pipe in the form of a spiral. In this case, the power calculation is calculated based on the number of turns and the distance between them;
  • If it is impossible to use the above options, the method of arbitrary wavy laying of the heating cable is applied.

Sequence of installation works: Types of heating cables.

  • A special foil tape must be pasted along the entire length of the pipe;
  • A cable is wound on top of it spirally( or otherwise), the distance between the turns should be approximately 10-15 cm;
  • On top of the second layer is again pasted adhesive tape, which in this case serves as a fixer, which will not allow unwinding and slipping of the wire;
  • All this turns into a heater, the joints between the cable and the heater must fit tightly together;
  • At the end of the process, this structure is wrapped with household tape;

It should be noted that according to the current building codes and regulations, the distance from the cable to the water pipes should be about 1.5 m.
