One, double threaded mounting electric heating pipe technology and uses: tubular heating element is a metal tube housing (iron, stainless steel, copper, etc.), along the central axis of the tube uniform spiral heating alloy wire (nickel-chromium, iron-chromium alloy) compacted fill its void with good thermal insulation properties of crystalline magnesium oxide sand nozzle ends sealed with silicone, and then by other process treatment from heating element. This metal sheathed heating element may heat the air, the metal mold and various liquids. It has a simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long life and other characteristics. Applicable to a variety of saltpeter tank, tank, tank, acid tank heating and fusible metal melting furnace, air furnace, oven, hot die and other devices. Widely used in aviation, shipbuilding, petroleum, chemicals, washing, chemical fiber, machinery manufacturing, automotive, electrical, radio, instruments, plastics, textiles, food, printing and packaging, rubber, pharmaceuticals, household appliances and other industrial sectors. Two, two-ply electric heating pipe heating pipe installation Caution: 1, component allow to work under the following conditions: A. Air relative humidity less than 95%, non-explosive and corrosive gases. B. Rated operating voltage should not exceed 1.1 times the shell should be effectively grounded. C. Insulation Resistance ≥ 1MΩ Dielectric strength: 2KV/1mi n 2, two-ply installation of electric heating pipe should do the positioning and fixing, effective heating area must be completely immersed in the liquid or solid metal, the non-air burning. Found in possession of the body surface scale or knot carbon, should be cleaned and then, in order to avoid shadow noon heat and shorten life. 3, heat fusible metal or solid nitrate, alkali, bitumen, paraffin, etc., should reduce the use of voltage, to be melted media to rise to the rated voltage. 4, the heating element should be cross air evenly, the element has good heat dissipation, the flow of air through heated sufficiently. 5, the heating nitrate safety measures should be considered to prevent explosion. 6, the wiring portion should be placed outside of the insulation layer, to avoid contact with corrosive, explosive material, water exposure; lead wire should be able to withstand the wiring portion of long-term temperature and heating load, terminal screw fastening should avoid excessive force. 7, the component should be stored in a dry place, If for long-term placement insulation resistance is less than 1MΩ, it would be about 200 ℃ oven drying, or lower voltage heating, insulation resistance until it is restored. 8, double threaded mounting electric heating tube outlet end of the magnesium oxide powder, the use of premises avoid contaminants and water infiltration and prevent leakage accidents.
