Pipe Heating and Tank Heating


A similar principle can be applied to process piping carrying fluids which may congeal at low temperatures, for example, tars or molten sulphur. Hit-temperature trace heating elements can prevent blockage of pipes.


Industrial applications for trace heating range from chemical industry, oil refineries, nuclear power plants, food factories. For example, wax is a material which starts to solidify below 70 °C which is usually far above the temperature of the surrounding air. Therefore the pipeline must be provided with an external source of heat to prevent the pipe and the material inside it from cooling down. Trace heating can also be done with steam, but this requires a source of steam and may be inconvenient to install and operate.



These types of cables are very popular due to their inherent safety and cut to length ability.
The general construction is that there are two conductors (bus-wires) providing a live and neutral supply along the length of the cable. A semi conductive heating matrix is extruded between these conductors forming the heating element.
Suitable electrical insulation is further extruded over the matrix providing the dielectric barrier.
The cable is then completed with options of a metallic braid and a further outer jacket for both mechanical and corrosion protection.
The function of the inner conductive core is to generate heat. The output will vary dependant on its temperature and the local environment. This is the self-regulating effect.
The advantage of the cable is that it cannot overheat and can be cut to the desired length. A potential disadvantage is the start-up currents which must be assessed and accounted for with any associated switch gear, thermostats or protection.
