EXT TAPE SELECTION GUIDE
CALCULATE WATTS REQUIRED PER METRE
Use tables above
A Heat losses per meter / temperature rise __________
B Correction factor for insulation thickness __________
C Thermal insulation efficiency factor __________
D Correction factor location __________
E Correction factor pipe material __________
Watts required per meter of pipe = A x B x C x D x E = W/M
Length of heating tape required = Pipe length metres x W/M
Wattage per M of tape selected
Spiralling Pitch
A Establish loading ratio of tape length to pipe length
Loading ratio = Total metres of heating tape required
Length pipeline (Metres)
B Using the chart below plot pipe diameter against loading ration to obtain spiral pitch.

Installation
Straight 
Tracing 
Attach to the underside of the pipe, fixing points every 250mm.
Spiralled Tracing 
Ensure firm contact, fixing points every 500mm.
Heating Tape must maintain firm contact with pipe and not be allowed to hang free or overlap upon itself. Control thermostats are recommended at all times.
