Steam Heat Tracing

More Information

The availability of steam at most chemical plant sites, coupled with its thermodynamic properties and relative ease of use, make steamtracing an attractive heat-transfer medium for many heat-tracing applications in chemical and petrochemical plants. Unitemp supplies quality steam tracing components suitable for a variety of steam tracing applications; including pre-insulated tubing, pre-form heat transfer products and heat transfer cement.

ThermoTube (Pre-insulated Tubing)

ThermoTube construction consists of a single insulated copper or stainless steel process tube ideally suited to transport steam, hot or cold liquids, gases or refrigerants. Pre-insulated with nonhygroscopic glass fibre, the tube is complete with a heat reflective foil wrap and a weatherproof outer covering. ThermoTube can also be manufactured in a variety of optional process tube materials, wall thicknesses and outer coverings to meet a multitude of applications.

Specifications / Ratings

Available standard tube diameters:1/4”, 3/8”, 1/2" & 3/4" (6,8,10,12 & 20mm)
Maximum process temperature:204°C
Minimum installation temperature:-10°C
Maximum recommended steam pressure:1825kPa

ThermoTube is supplied in long length coils and can be quickly and easily installed. The pre-insulated feature of ThermoTube allows installation to be completed in one step as opposed to multiple steps required when using field-installed materials. Ease of installation is further enhanced by the ability to attach ThermoTube to existing cable trays, angles, channels, struts and I-beams.

SnapTrace (Heat Transfer Compound)

SnapTrace is flexible heat transfer compound (preformed in 1.22m sections) designed for rapid installation on straight piping runs. Unitemp’s heat transfer compounds provide an efficient thermal connection between the tracer and the process pipe. By eliminating the air voids that would normally exist, heat is directed into the pipe wall primarily through conduction rather than convection and radiation. A single tracer utilizing snap trace has the equivalent performance of 3 to 5 air convection (bare) tracers. Snap Trace includes TFK galvanised steel channel, providing mechanical and weather protection to the installation.

Specifications / Ratings Benefits of SnapTrace include:
Minimum process pipe diameter:40mm
  • no surface preparation required
Minimum steam pipe diameter:12mm
  • installation times are 5 times faster
Maximum exposure temperature:208°C
  • non-soluble in water
Minimum exposure temperature:-73°C
  • requires no curing procedures
Minimum installation temperature:-12°C
  • increases heat transfer rates significantly over bare traci
  
  • factory-formed to fit the tracer and pipe.
