The quality of Dryer Industrial Bendable Tubular Heating Element depends on the following six major factors: electrical strength, insulation, leakage current, power accuracy, life, corrosion resistance, and scale.

       1. Electrical strength: The factors affecting the electrical strength of the Black Oxide Industrial Tubular Heating Element mainly include the thickness of the insulating layer, the mass of the insulating layer, the length of the Black Oxide Industrial Tubular Heating Element, the radius of the tortuosity and the number of tortuosity. Suxin electric heating equipment can usually achieve 2000V, 1 second, and the breakdown current is 0.5mA in the cold withstand voltage of the electric heating tube.

       2. Insulation: The primary factor affecting the insulation of Stainless Steel 304 Industrial Tubular Heating Element is the sealing technology of Stainless Steel 304 Industrial Tubular Heating Element. Suxin electric heating equipment can usually achieve more than 1000 megohms.

       3. Leakage current: It is mainly related to the temperature when the Incoloy 800 Industrial Tubular Heating Element is used, the operating voltage of the Incoloy 800 Industrial Tubular Heating Element, and the heating length of the Incoloy 800 Industrial Tubular Heating Element. An important check target for high temperature Incoloy 800 Industrial Tubular Heating Element.

       4. Power accuracy: It is mainly related to the quality of the resistance wire and the technical level of the manufacturer. Suxin electric heating equipment needs to do the temperature coefficient experiment before mass production to determine the cold resistance of the qualified power scale.

       5. Lifespan: In addition to the quality of the electric resistance wire, the life of the Stainless Steel Coil Tubular Heating Element is related to the quality of the magnesium oxide powder and the selection of the diameter of the electric resistance wire. With regard to high-temperature electric heating pipes, Suxin electric heating equipment can produce electric heating pipes with an external load of 8W/CM2 or less. When selecting the diameter of the resistance wire, it is necessary to calculate the external load of the resistance wire to reach the life requirement.

       6. Corrosion resistance is a common problem encountered in water heating Stainless Steel Coil Tubular Heating Element and barbecue electric heating pipes. In addition to reasonable selection of materials, it is also related to the heat treatment of the Stainless Steel Coil Tubular Heating Element and the appearance of the Stainless Steel Coil Tubular Heating Element.


The quality of the heating tube mainly depends on the following aspects: insulation, leakage current, electrical strength, corrosion resistance, power accuracy, and life.


1. Leakage current: It is mainly related to the temperature when the heat pipe is used, the use voltage of the Stainless Steel 304 Coil Tubular Heater, and the heat generation length of the Stainless Steel 304 Coil Tubular Heater. An important evaluation indicator for high temperature Stainless Steel 304 Coil Tubular Heater.

2. Electrical strength: The factors affecting the electrical strength of the heating pipe mainly include the thickness of the insulating layer, the quality of the raw material of the insulating layer, the length of the heating pipe, the radius of the bending and the number of bending. Qiaohua Electric Appliance Factory can generally achieve 2000V, 1 second, and a breakdown current of 0.5mA in the cold withstand voltage of the Stainless Steel 304 Coil Tubular Heater.


3, life: the life of the heating tube in addition to the quality of the resistance wire, but also related to the quality of magnesium oxide powder, the choice of resistance wire diameter and other factors. For high-temperature heating pipes, Qiaohua Electric Appliance Factory can manufacture heating pipes with surface loads below 8W/CM2. When selecting the diameter of the resistance wire, the surface load of the resistance wire needs to be calculated to meet the life requirement.
