RICWILSKINEFFECTCURRENTTRACEDSYSTEMS The Most Reliable Cost-Effective Heat Tracing System For Long Pipelines Control Panel Power Transformer Exterior surfaces of SKIN EFFECT CURRENT SYSTEMS are electrically grounded. The voltage is impressed between the cable and the inner surface of the heat tube. Service Pipe

Electric SKIN EFFECT CURRENT TRACING combines the engineering principles of skin effect and proximity effect. Skin effect is an alternating current phenomena whereby AC current flows in the outer surface of a carbon steel conductor. Proximity effect is an electromagnetic force whereby equal currents in opposite directions attract. By placing the electric cable inside the heat tube, the current is drawn to a thin section of the heat tube inner wall. Heat generated from the current is dispatched through the heat tube wall and into the service pipe by conduction. Custom Designed and Supplied...

Applications The effective maintenance temperature range for SKIN EFFECT CURRENT TRACING is +35°F to +350°F. (will withstand -80°F to +450°F) Typical SKIN EFFECT CURRENT TRACING applications include: • WATER • ACIDS • FOODS • OILS • GASES • BASES • CHEMICALS • RESINS • HYDROCARBONS PRODUCTS RICWIL SKIN EFFECT CURRENT TRACING SYSTEMS are custom designed for both single and multiple pipe applications. The multiple pipe configuration enables non-metallic pipes to be efficiently heat traced and also provides secondary containment for the pipeline. SKIN EFFECT CURRENT TRACING SYSTEMS can be...

Heat Tracing is the use of an externally applied heat source on a pipeline to compensate for heat losses through the thermal insulation. Heat tracing evolved from the need to maintain the flow of low, medium and high temperature liquids through a pipeline, regardless of the surrounding environment. The primary applications for heat tracing are: 1) freeze protection, 2) temperature maintenance and 3) heat/reheat. Early heat tracing methods, utilizing steam or hot fluids, were inefficient in their use of thermal energy and their ability to maintain a uniform temperature along the pipeline....
