Introduction to the application scope and maintenance of stainless steel electric heating pipes

Stainless steel electric heating tubes are made by placing metal resistance wires in a metal tube and filling the gaps with crystalline magnesium oxide with good thermal conductivity and insulation. Stainless steel electric heating tubes can be installed in air ducts to heat air, or immersed in water or other liquids to heat water or other liquids, and directly placed in solid metal to heat metal. Stainless steel electric heating tubes have the characteristics of simple structure, high thermal efficiency, good mechanical strength, safety and reliability, lightness and durability.

Stainless steel electric heating tubes are suitable for saltpeter tanks, water tanks, various oil tanks, acid and alkali heating devices. Fusible metal melting furnaces, drying ovens, various dies, die presses, electric irons, water boilers, cookers, etc. Electric heating tubes are a type of equipment that is used more frequently in work and life, such as electric furnaces, electric soldering irons, electric irons, electric heaters, electric ovens, etc. are all electric heating equipment. Stainless steel electric heating tubes are electrical components that convert electrical energy into thermal energy. Due to their low price, easy use, easy installation, and pollution-free characteristics, they are widely used in various heating occasions. The service life of stainless steel electric heating tubes is very long, and the general design service life is more than 10,000 hours.

It should be noted during use that since the power of stainless steel electric heating tubes is relatively large, if the user ignores safety, fire may occur at any time. Therefore, flammable and explosive items should not be placed near stainless steel electric heating tubes during use, and a certain safe distance must be maintained. Stainless steel electric heating tubes must be placed on a non-conductive non-combustible material base; the safe interception volume must meet the capacity requirements of the electric heating tube, and industrial stainless steel electric heating tubes must be equipped with a separate circuit under any circumstances. The wires of stainless steel electric heating tubes must be installed with plugs, and the wire ends cannot be directly inserted into the socket; aging and damage should be replaced in time, and electric heating tubes without fuses installed in the explosion-proof electric heating tube circuit shall not be used; someone must be in charge when using it, and the plug should be unplugged when leaving. During use, if there is a power outage, the plug should be unplugged in time, and don't forget it.

Generally, the insulation resistance should be tested regularly. If it is less than the specified value, the electric heating tube should be placed in an oven for drying to prevent moisture damage. When installing stainless steel electric heating tubes, read the instructions carefully. The heating medium must not corrode the heating tubes, which can easily cause the equipment to corrode and become unusable. The operating voltage of stainless steel electric heating tubes should be stable. If the voltage is very unstable, it is not recommended to use it or use it after using a voltage stabilizer. Electric heating tubes have specified requirements for air humidity. Under normal circumstances, the humidity of the air cannot be greater than 95%, and there must be no explosive or corrosive gases in the air. The normal working voltage of the equipment cannot exceed 1.1 times the rated voltage.

Electric heating tubes cannot be placed in humid places, but they cannot be directly exposed to the sun. When not in use, placing them in a cool, ventilated place will have a good protective effect on the equipment. After the electric heating tube is used, the main power supply must be cut off in time, especially in unsatisfactory natural environments, such as rainy weather, when the air will be relatively humid. Cutting off the power supply can better protect the equipment. There will definitely be scale and other dirty substances on the inner wall. These must be cleaned up in time, otherwise it will not only affect the heating effect, but also be more difficult to clean over time.
