4. GREASE WASTE Standards
IEeE for design & installation heat tracing
Maintain Temperature = 109.4°F to 120.2°F
Line Sensing Control
Fluoropolymer Outer Jacket on Heating Cable
Buried Pipe - Delta T for Heat Loss = soil temp – maintain temp
Plastic Pipe = Two lower watt heaters vs one higher watt heater
Plastic Pipe = Aluminum Tape over heating cable
Label Pipe – “Heat Traced”
