In some severely freezing cold climates, most of the time, water or chemical pipelines often needs to be heat traced to achieve pipe freeze protection. However, merely concentrating on thermal insulation of pipes is absolutely not enough to ensure pipe freeze protection. As you can see, A drill pipe with 25 mm thick insulation at 5°C will quickly reach freezing point in less than an hour in an ambient temperature of -10°C. What's more, steam at 150°C is not a viable fuel source that can be used for freeze protection. Above all, the cold condensate return water will definitely freeze in this operation process. In view of those factors, an electric heat tracing cable with much lower output power is exactly a cost-effective and highly efficient option that can meet your various needs.

For those reasons, we highly recommend the following types of heat tracing products, which are included but not limited to self-regulating heating cable, parallel constant wattage heating cable and RDC series constant wattage heating cable.
