How to operate the explosion-proof flange heating tube to make the service life longer?

On the one hand, it is necessary to ensure the high quality of the electric heating tube, and on the other hand, we can extend the life of the electric heating tube through some professional knowledge and small methods! Here is an introduction:

⒈ Input power, the voltage should not exceed 10% of the rated voltage marked on the various electric heating tubes. If it is applied to a voltage lower than the rated voltage, the heat generated by the heating tube will also decrease.

⒉The terminal of the electric heating tube should be relatively fastened with two nuts when wiring. Don't use too much force to avoid the loosening of the lead screw and damage the electric heating tube.

⒊The heating tube should be stored in a dry warehouse. If the surface is damp due to long-term storage, use a megohmmeter to measure the insulation resistance. If it is less than 1 megohm/500 volts, the electric heating tube should be placed in a 200 degree drying oven for drying.

⒋The heating part of the electric heating tube should be completely immersed in the heating medium to prevent the electric heating tube from being damaged by the undesirable heat dissipation and exceeding the allowable heating temperature. In addition, the lead-out part of the wiring should be exposed to the heat insulation layer of the heater or outside the heater, so that this part should not be overheated and damaged.
