Heat Trace Tape Control for HVAC Piping Quality 101
https://highperformancehvac.com/heat-trace-tape-control-for-hvac-piping/
Heat Trace Tape Control for HVAC Piping Heat trace tape looks similar to Romex and simply provides electrical resistive heating for the pipe. Heat trace tape is made of many layers that begin with the heat trace wire. The wire inside the insulation (typically 16 AWG) that heats up is surrounded by a conductive core.
Heat Tracing of Piping Systems - Effective Steam Tracing
https://wermac.org/documents/steam_tracing.html
The most common diameters of steam tracing are 3/8 in. (9.52 mm) and 1/2 in. (12.7 mm) OD copper or stainless steel tubing. Diameters of 5/8 in. (15.88 mm) and 3/4 in. (19.05 mm) OD tubing have been used; however, this entails greater expense. Tubing that is 3/8 in. is more easily plugged by sediment and/or debris, so it is less frequently used.
HEAT TRACING AQUATHERM PIPE
https://aquatherm.com/tech-bulletins/heat-tracing-aquatherm-pipe
When using any type of external heat source applied to Aquatherm piping, such as heat tape, heating cables or hot water maintenance cables the product must be: 1. Suitable for use with plastic piping. 2. The heat system must be self-regulating and ensure the surface temperature of the Aquatherm pipe and fittings will not exceed 158ºF (70°C). 3.

Step 2.Determine Pipe Heat Loss Find QP in Table 1 (page 2) for the nominal pipe size and insulation thickness based on ΔT. For example, for a 3" (76 mm) pipe with 2" (51 mm) insulation and ΔT = 60ºF (33.3ºC), the value for QP is 5.5 W/ft (10.8 W/m). THERMAL DESIGN- PIPES Step 3.Adjust for Insulation Table 1 (page 2) is based on ASTM C547 ...

• Self Regulating Hot Water Maintenance Heat tracing is used to counteract the heat lost from process equipment and piping through its insulation. A heat tracing system is a group of process equipment and piping which is heat traced and controlled in a logical and economical manner. There are many reasons for making up the heat loss of a ...

http://thermalpipesystems.com/heat-tite/
Heat-Tite is a steel piping system featuring a gasketed coupling with built-in expansion control for condensate, low temperature hot water, dual temperature, or chilled water service. Heat-Tite is a top quality, energy efficient piping system that is easy to install. The standard carrier pipe is Schedule 40 A53 steel pipe with the sealing ...
CHAPTER B6 HEAT-TRACING OF PIPING SYSTEMS
http://www.123seminarsonly.com/Seminar-Reports/039/54519342-Heat-Tracing.pdf
Heat-tracing may be avoided in situations where heat loss to the environment can be effectively minimized. In cold climates or areas with severe winters, water pipes are often buried below the frost line. Alternatively, they may be kept from freezing by …

From the diagram above - 80 mm fiber glass insulation, temperature difference 80 oC and pipe dimension 2 1/2" - the heat loss is approximately 20 W/m. The heat loss from the whole pipe can be calculated as ( 100 m) (20 W/m) = 2000 W Pipe Heat Loss - Insulation thickness 50 mm Pipe Heat Loss - Insulation thickness 40 mm
Propylene Glycol vs Heat Trace - HVAC/R engineering
https://www.eng-tips.com/viewthread.cfm?qid=157745
Provide vents & drain valves to completely drain the outdoor piping including the chiller evaporator. Check requirement of your state. Use of food grade propylene glycol may be required. This is more viscous and less thermally efficient as ethylene glycol but it has no environmental hazard concern. lilliput1 sterl (Mechanical) 29 Sep 06 17:31
