Electric heating elements lifespan

- Sep 02, 2019-

The stainless steel electric heating tube is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use and no pollution, it is widely used in various heating occasions. Stainless steel electric heating tube has a long service life. The general design life is more than 10,000 hours, which is equivalent to 5 heating seasons. If you pay attention to maintenance work, you can further extend its service life.

1. The input power of the stainless steel electric heating pipe should not exceed 10% of the rated voltage on the various stainless steel electric heating pipes. If it is lower than the rated voltage, the heat generated by the stainless steel electric heating pipe will also decrease. .

2, stainless steel electric heating tube terminal, the two nuts should be relatively fastened when wiring, do not use too much force to avoid the loosening of the screw and damage the stainless steel electric heating tube.

3, stainless steel electric heating tube heating part should be fully immersed in the heating medium to avoid heat dissipation is not fast and exceed the allowable heating temperature to damage the stainless steel electric heating tube. In addition, the wiring lead-out part should be exposed outside the heater's insulation layer or heater so that this part should not be overheated and damaged.

4, the selection of stainless steel electric heating tube should pay special attention to the heating medium. It should not corrode the stainless steel electric heating shell material.

5. The stainless steel electric heating tube is used for a long time. If the surface gathers thick tube scale and grease stain, it should be removed regularly. Otherwise, the heat transfer performance of the stainless steel electric heating tube will be reduced and the heat load on the surface of the tube will exceed the rated allowable damage.

6, stainless steel electric heating pipe should be stored in a dry warehouse, if the surface is damp due to long-term placement, the insulation resistance is measured using the application of a megohmmeter. If it is less than 1 megohm / 500 volts, the stainless steel electric heating tube should be placed in a 200 degree drying oven for drying.

7. When heating certain adhesives and other materials, such as sodium, stearic acid, paraffin, etc., the power supply voltage should be lowered when heating, so as to reduce the heat generation of the stainless steel electric heating tube. Then rise to the rated voltage for heating.

8. Special stainless steel electric heating tube should be read in detail before installation and use, so as not to damage it.

9. The terminal of stainless steel electric heating pipe should be kept clean and dry, otherwise it will reduce the insulation performance and be short-circuited. If it is used in the environment of chemical corrosion, flammable, explosive and other liquid or gas, stainless steel electric heating pipe should be used. The wiring part is protected by an insulating sealing device to prevent accidents.

In fact, the length of life of the stainless steel electric heating tube really depends on the design of the stainless steel electric heating tube at the beginning, the selection of the internal material of the stainless steel electric heating tube and the choice of external materials. Find out the working environment of stainless steel electric heating tubes, and correctly select the various materials of stainless steel electric heating tubes, which is crucial for the real service life of stainless steel electric heating tubes.

According to the national standard, the normal stainless steel electric heating tube can be replaced with new ones in 6 months. The country is in terms of safety. 6 months is the most insured life cycle. Actually, according to our work experience, stainless steel electric heating tube As long as it is used properly, the life span can be roughly one year or more and even longer. This life-related time is closely related to the working environment of stainless steel electric heating tubes.
