Mineral insulated heating cables have incomparably superior performance. In a large number of application practices in China, the advantages of mineral insulated heating cable technology in the field of industrial production are summarized, that is, mineral insulated heating cable technology should be used to solve key cases.

1 High temperature characteristics

Long operating temperature exceeds 150 ℃, whether it is electric heating or electric heating of the pipeline, the organic insulation electric heating method is used, and the service life is definitely not long. In order for the device to achieve a reliable long service life and achieve the expected technical and economic advantages, it is necessary to use heating cables with inorganic insulation MI.

(1) After the electric heating of the oil field fired wells (high temperature working area + 600 °C) failed, we used the MI heating cable technology to meet the requirements of the owner.

(2) Molten salt pipelines and tanks used for energy storage in solar power plants require an operating temperature of + 400 °C.

(3) When special steel pipes are welded in the field, the weld temperature should reach 100 °C for 20 minutes before the first root welding can be started. We use mineral insulated heating cables which are heated to 400 ~ 500 °C to solve the problem.

A mineral insulated heating cable is used to penetrate the collection pipeline to realize internal heating, and only the mineral insulated heating cable has the characteristics of direct penetration into the collection pipeline. First, the electric heating efficiency reaches 100%, which is more important, if the pre-assembly line is clogged with condensate, this can no longer be considered an accident, because it is very convenient to deal with and eliminate clogging. Patiently supply power to a mineral insulated heating cable to melt a layer of liquid around the mineral insulated heating cable, and then pump oil with heat to open the pipeline. Or have enough patience to supply power to the MI heating cable for a long time (such as 30 ~ 48 hours) until the blocked oil in the pipeline returns to temperature. The move could once and for all allay the concerns of oil field leaders.

5 excellent SD can replace a large number of traditional tubular electric heaters

SD is an important parameter of the heating element, the unit of measurement is w/° Cm' (amount of electric heat per square centimeter). Traditional SD tubular electric heater, national standard 3 ~ 7. MI heating cables can reach 0.1 ~ 10. The versions of heating cables with MI are significantly wider than those of visible ones. Especially when heating viscous and thick liquids, the characteristic advantages are more significant.
