Installation using plastic pipes.
When using plastic pipes, the general installation principles for heat-tracing
of plastic pipes should be respected (i.e. using Aluminium tape ATE-180 as
installation method). It is only allowed to use plastic pipes with minimum
temperature rating of 90°C. If correctly installed, the temperature behaviour
will be comparable with metal piping. Deviations of temperature can be
compensated for by using the 'Power Correction Factor'.
Special applications
Installation on composite pipes
The maximum allowed surface temperatures needs to be considered in case
of use of composite pipes. If special applications are wanted, heat loss
calculations must be performed to predict achievable temperatures.
Contact your local Tyco Thermal Controls supplier for assistance and advice.
