For frost protection of pipes, heating cables are used to maintain a high enough temperature to avoid the pipes of freezing, whether the pipes are in the ground or inside buildings; such as hot water pipes or drinking water pipes. Both regular TXLP heating cable and self-limiting heating cables can be used.
Series resistance single conductor heating cables are installed in one or more loops on the surface of the pipe or spiraled in order to give the correct load.

Self-limiting heating cables and parallel resistance heating cables are normally laid straight along the pipe or spiraled in order to give the correct load.

The heating cables are fixed to the pipe by means of a temperature resistant tape. The best thermal contact and heat distribution is achieved by wrapping an aluminium foil over the heating cable before the insulation is applied. The insulation must be suitably protected against moisture or water.

On flanges and vents on process piping, 1-1,5 m (40 -60")of heating cable is wrapped carefully in such a way that uncoupling can be done later if necessary.

Thermostat control is recommended in order to maintain a steady temperature and save energy. An electronic thermostat with a remote sensor should be used.

Heating cables can also be used for maintaining temperatures of tanks or to provide frost protection.

Please see our heating cable handbook for further information regarding pipes and tanks.
