The instrument pipelines in power plants, such as main steam flow, outlet steam pressure, drum saturated steam pressure, and reheater inlet steam pressure, are prone to freezing and blocking in winter due to their small diameters. Therefore, power plants now commonly use electric heat tracing to keep the pipelines warm. However, leaks may occur at valve or transmitter interfaces, causing the pipeline temperature to rise significantly, sometimes reaching 600 degrees. As a result, standard electric heat tracing cables or heating cables cannot be used normally on such pipelines. But MI heating cables, with their high-temperature resistance, are perfectly suited for the job.

Our company's dedicated electric trace heating system for power plants, chemical factories, cement plants, etc., is specifically designed for special electric tracing heaters and MI mineral insulated heating cables used in steam piping. The characteristic of our electric tracing heater is the addition of an insulating layer between the sheath and shielding layer, which can be directly installed on the pipe walls with steam lines. The MI mineral insulated heating cable, due to its unique structure and materials, can withstand temperatures up to 800°C, offers customizable power from 5W/M to 269W/M, and features even heat distribution, thereby eliminating the inconvenience of using insulating clamps and other insulating methods for installing electric tracing heaters in steam pipes.

Not only does it save installation and maintenance costs, but also, as the electric heating tape and MI mineral insulated heating cables are directly installed on the pipe wall, they provide a more direct and effective heat tracing effect, thereby reducing energy consumption and operating costs. Therefore, the specialized electric heating tape for steam pipes and MI mineral insulated heating cables are excellent products for preventing freezing and heat tracing of steam pipes.
