Mineral insulated heating cable (international nominal MI cable) I. Introduction mineral insulated heating cable (international nominal MI cable) is the use of high-purity alloy heating wire as a heat source, high-purity, high temperature, high crystallinity of magnesium oxide for thermal insulators, seamless stainless steel or brass as sheathing, using a special manufacturing process. Second, the product uses: 1, petrochemical industry: container heating, process pipe insulation, tank with heat insulation clear wax plugging the oil pipeline. 2, heating insulation: building large heating plants, warehouses holding agriculture horticulture greenhouse heating, thermostatically controlled heating poultry. 3, outdoor equipment and facilities in cold areas: machinery and equipment runway stadium, football television transmission tower culverts, Chokes transportation hub facilities, schools, hospitals open-air stage intermittent liquid pump. 4, oil platforms and offshore boating: cabin deck anti-condensation heating fluid piping insulation heat insulation of machinery and equipment. 5, preheat combustion devices: nuclear reactor fuel boiler preheater preheat gas unit heaters. 6, runways, railway rail, road forks, etc. need to be heated, insulation place.
