MI armored heating cable, also known as mineral insulated heating cable, is a solid body composed of electric heating wire material, inorganic insulation (such as magnesium oxide, aluminum oxide, etc.), and metal protective tube. It is tightly compacted by a mold and is particularly suitable for heat tracing of high-temperature pipelines. MI armored heating cables have the advantages of pressure resistance, earthquake resistance, flexibility, energy saving, high impermeability, radiation resistance, explosion prevention, safety and reliability, easy installation, high mechanical strength, and long service life, especially in pipelines that require high output efficiency or need to withstand high-temperature steam blowing, as well as industrial sectors such as aerospace, nuclear energy, petroleum, chemical industry, construction, machinery, and power energy, and scientific research and teaching fields. In environments that require anti-corrosion and explosion-proof, MI armored heating cables can better reflect their excellent characteristics. These high-quality features have been verified internationally for more than 40 years.
