The double-head threaded electric heating tubes produced by Zhai's Electric Heating are bent from high-quality seamless electric heating tubes, and the metric (imperial) system with hexagonal heads is welded to the wiring section. Hollow bolts for sealing installation.
Zhai's double-head threaded electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life.
Precautions for the use of electric heating pipes installed with double-head threads:
The components are allowed to work under the following conditions:
． The relative humidity of the air is not greater than %, and there are no explosive and corrosive gases.
B. The working voltage should not be greater than .times of the rated value, and the shell should be effectively grounded.
C. Insulation resistance && dielectric strength:
Electric heating tubes installed with double-headed threads should be positioned and fixed. The effective heating area must be completely immersed in liquid or metal solids, and empty heating is strictly prohibited. When scale or carbon is found on the surface of the pipe, it should be cleaned in time before use to avoid affecting heat dissipation and shortening the service life.
When heating fusible metals or solid nitrates, alkali, bitumen, paraffin, etc., the voltage should be lowered first, and then the voltage can be raised to the rated voltage after the medium is melted.
When heating air, the elements should be arranged evenly across each other so that the elements have good heat dissipation conditions and the air flowing through can be fully heated.
When heating nitrate salt, safety measures should be taken into consideration to prevent explosion accidents.
The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. Excessive force should be avoided when tightening the wiring screws.
Components should be stored in a dry place. If the insulation resistance is lower than & due to long-term storage, they can be dried in an oven at about ℃, or the voltage can be reduced and heated until the insulation resistance is restored.
Zhai's double-headed thread is used to install the magnesium oxide powder at the outlet end of the electric heating pipe to avoid the penetration of pollutants and moisture in the use place and prevent the occurrence of leakage accidents.
