Product Description

Self regulating heating cable for process temperature maintenance

    In general, pressure piping refers to those pipelines bearing pressure from internal or external no matter what media they carry.
To prevent condensation/ solidification or increase of viscosity and maintain temperature, indirect heating should be necessary from inside or outside the pipelines.
   

 

    Electric heat tracing can be adopted maintain pipeline temperature. The media that pipelines carry can be gas, liquefied gas, steam. They can be inflammable, explosive, toxic or corrosive; and their maximum operating temperatures can be higher or equal to their boiling points.
    When the ambient temperature is too low, the medium temperature may be lower than the solidification/condensation point. To prevent heat conduction between the medium and the outside, it is necessary to have appropriate heat tracing for the pipeline. In choosing heat preservation systems, the following aspects should be taken into account:

1. Is the site conditions characterized with inflammable/ explosive atmosphere?
2. Will the heat preservation system accelerate corrosion of pipelines? Inappropriate heat tracing may give rise to safety accidents,

    Sanniu's specialized electric heat tracing system is an ideal choice and solution. By far, Sanniu has successfully designed and installed electric heat tracing systems for various pressure pipelines.
    In choosing appropriate electric heat tracing cables, we must use the enhanced type (explosion-proof & corrosion-resistant) heat tracing cables. Subject to different media, there are electric heat tracing cables of several temperature groups to choose from. For gas media, the explosion-proof & corrosion-resistant self-regulating heat tracing cables can be used; for liquefied gases requiring relatively higher temperature maintenance and for long pipelines, constant wattage heat tracing cables (0-180ºC) may be a good choice; if the internal medium temperature is very high, e.g. steam, MI heating cable (0-600ºC) is good choice. All these cables are fire retardant and explosion-proof.

Product discription

Summary
Self-regulating heating cable is constructed of a semiconductor heater and two parallel bus wires with the addition of insulation layer, The heating elements are parallel to each other and its resistivity has a high Positive Temperature Coefficient "PTC". It has the characteristics of automatically regulating the temperature and output power when heat; It can be sheared to use and overlapped by itself without the problems of overheat and burnout.

Working Principle
In each self regulating heating cable, circuits between the bus wires change with the ambient temperature. As temperature decreases, the resistance decreases which produces more output wattage; Conversely, as temperature increases, resistance increases which lower the output wattage, loop back and forth.

Features 
1. Energy efficient automatically varies its power output in response to pipe temperature changes.
2. Easy to install, can be cut to any length (up to max circuit length) required on site with no wasted cable.
3. No overheat or burnout. Suitable for use in non-hazardous, hazardous and corrosive environments.

Applications
1. Processing of agricultural and sideline products and other applications, such as fermentation, incubation, breeding.
2. It applies to as all kinds of complicated environment such as ordinary, danger, corrosion, and explosion-proof areas.
3. Frost protection, ice-melting, snow-melting and anti-condensation.
