Introduction:


“MI metal heating cable” is evolved from the magnesium oxide insulation fire-proof cable.It is composed of alloy heating core, high purity magnesium oxide and metal sheath.Products has non-aging, long life, high intensity, high temperature resistance, flame-retardant, fire-proof, waterproof,strong corrosive resistance and radiation resistance and other properties. Especially suitable for heat tracing and heating of 200～600℃ pipelines.

Application area:


◆　Petrochemical：heat insulation of vessel heating, pipeline process, storage tank heat tracing insulation and wax cleaning and plug removal of petroleum pipelines.
◆　Heating insulation：for big area heating factory of buildings, warehouse heat insulation, heat supply of agricultural gardening house, and constant temperature control of poultry heating.
◆　Outdoor equipment and facilities in cold areas：mechanical equipment, airplane runways, playgrounds, soccer fields,television transmission tower, culverts, valves, transport hub facilities, schools, hospitals, outdoor stairs, intermittent liquid pumps, railway rails, road cross, etc.
◆　Petroleum platforms and offshore ships：deck anti-condensation, cabin heating fluid, fluid pipeline heating and insulation, mechanical equipment insulation.
◆　Combustion preheater：nuclear reactor preheating, fuel boiler preheater, gas unit preheater.

Functions and its Characteristics:


◆　Wide using range:MI metal heating cable structural size (generally about Φ3～Φ8mm), it can be used for any special surface, such as valves,pumps,pipelines,concrete road pavements,asphalt pavements,gravel pavements.
◆　Explosion-proof:MI metal heating cable is a tight solid structure made of seamles smetalsheath , compacted magnesium oxide material and heating conductors, it can withstand huge external impact force.
◆　Impermeability:The seamless metal sheath allows the cables to be totally immersed into liquids for laying, or be laid in vacuum,pressurized locations.
◆　Non-flammableSince the materials composing cables are inorganic, it determines that the cables are non-flammable, it can continue to run under fire conditions, and will not produce any harmful gases.
◆　Radiation-resistance:Cables use inorganic materials, no changes will occur after materials are radiated, they can maintain higher insulation resistance, thus owning good stability.
◆　Long service life:Due to the inherent properties of materials composing cables, the stability, long life ser vice of cables can be ensured, the cable can be used for more than 20 years, no need of maintenance, saving the maintenance labour.
◆　Safe and reliable:High insulation, impermeability of cables and system's comprehensive protection measures, making the whole system running more secure and reliable.
◆　Energy saving Cable capacitance and inductance is very low, with also small thermal inertia, high power sensitivity. It can be used in the temperature range lower than 600℃, and the accuracy of temperature control can reach ±1℃.
