2.1 Maintaining the temperature of a petrochemical oil unit with heater ribbons
To maintain the temperature of an oil unit, the user has defined the geometric characteristics of the lines to be drawn and the calculation assumptions:
temperature to be maintained: 80 C to ± 5 C ;
minimum outside temperature: – 15 C ;
pipe diameters: 4 and 6 inches ;
total length of all pipes to be traced: approx. 10,000 m ;
thermal insulation: 40 mm thick rock wool;
no preheating required.
A specialist manufacturer was entrusted with all the thermal studies,...

TRACE software, developed by EDF R&D, is used to design pipe temperature maintenance systems for heating tapes, mineral insulated cables, shielded resistors, current flow tubes and heating effect tracer tubes. It is a tool for thermal and electrical calculations.
For thermal applications, the following calculations can be made:
