Nickel-chromium heating wire for electric heating insulation tube

Nickel-chromium heating wire for electric heating insulation tube

Metal heating tubes are widely used in electric heating products. The best metal is nickel-chromium heating wire, which is also the most widely cited, and the worst is iron-chromium heating wire, which is less used. The most commonly used are nickel-chromium wire electric heating tubes, which are divided into stainless steel electric heating tubes, iron electric heating tubes, copper electric heating tubes, etc.; there is a layer of magnesium oxide between the metal tube and the heating wire (with excellent insulation effect and thermal conductivity) Material), in accordance with the requirements of the national standard, it is generally required to withstand the high voltage test of 1250V to pass the electrical strength. Most of the storage-type electric water heaters also use this type of heating method, such as companies such as Haier, Smith, Ariston, etc., because this method is a relatively mature and relatively inexpensive electric heating method, so it is broadly used. Iron electric heating tubes are used in electric water heaters, but because they are very easy to rust, they are rarely used. Stainless steel electric heating tubes are more widely used, but they are prone to scale. They are not as widely used as copper metal electric heating tubes, but copper electric heating The relative cost of the tube is relatively high, and the best is the copper electric heating tube, but the current application ratio only accounts for 10% of the metal electric heating tube.

This kind of appliance is mainly used in: electric mosquito repellent, dryer, hand warmer, electric heating plate, electric soldering iron, electric iron, curling iron, electric heating adhesive, etc. The functional characteristic of this heater is that the power is small, but the thermal efficiency is very high, which is very practical.

Electric heating tube automatic constant temperature type

This kind of appliance is mainly used in various heat preservation equipment such as small crystal device constant temperature bath, electronic thermos bottle, constant temperature incubator, heat preservation box, heat preservation plate, heat preservation cup, heat preservation table, heat preservation cabinet and so on. Its functional characteristics are simple structure, automatic heat preservation, high thermal efficiency, good constant temperature characteristics, and wide use environment temperature range.

High resistance electric heating alloy material for electric heating insulation pipe

(1) Iron-chromium-aluminum and other high-resistance electric heating alloy materials: the characteristics of this material are: low temperature coefficient of resistance, high resistivity, and high operating temperature. It has good corrosion resistance at high temperatures and is very suitable for use in atmospheres containing sulfur and sulfide, and has a relatively low cost. It is an ideal heating material for household appliances, industrial electric furnaces, and far-infrared devices.

(2) Nickel-chromium material: This material has the characteristics of strong plasticity and high high-temperature strength. It is widely used in household appliances, industrial electric furnaces, far-infrared devices, etc.
