STS-MT Skin-Effect Freeze Protection Heat Tracing Cable - Raychem

Maintains Temperatures up to 150 °C


RAYCHEM STS-MT Skin-Effect Heat Tracing Cables offer freeze protection and process temperature maintenance, specifically designed for embedded or long pipeline applications. STS-MT Heating Cables facilitate circuit lengths of up to 15 miles/25 km, reducing the number of connection and power source locations required. Capable of handling applications up to a maximum of 302 °F/150 °C, they are approved for use in both hazardous and non-hazardous locations. The polyolefin outer jacket makes them particularly suitable for heating pipelines transporting materials like crude oil, VGO, and phenol.

The STS-MT Tracing Cable, conforming to internationally recognized standards such as IEEE 844.1/CSA C22.2 No. 293.1 and IEEE 844.2/CSA C22.2 No. 293.1 at 5,000 VAC, is specially formulated for medium-temperature STS Skin-effect Tracing System applications. They are certified for use in hazardous and non-hazardous locations when integrated into a nVent-designed STS Trace Heating System, meeting requirements of the U.S. National Electrical Code and Canadian Electrical Code.

The RAYCHEM STS-MT Skin-Effect Trace Heating Cables provide a safe, efficient, and reliable solution for freeze protection and process temperature maintenance in embedded or long pipeline applications, offering versatility and durability in various environments and applications.
