Trace heating cable are vital in ensuring that process temperatures of pipes and vessels are maintained to allow for smooth and efficient running of process plant equipment. When subjected to low ambient temperatures or 'No Flow' conditions, heat loss can cause the contents viscosity to increase. This can cause the material to harden or set within the pipework, either slowing down the process or causing problems to pumping equipment. To minimise the effects of heat loss trace heating is used in conjunction with thermal insulation to supply a heat source to replace this heat loss and therefore maintain the pipe temperature. Typically, a pipe sensing thermostat is used to sense the pipe temperature and energise the trace heating when required. By utilising the correct type of Heating Cable, Thermal Insulation and Temperature Control, process pipework will operate efficiently for many years.
