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 section for a long time, and excessive force should be avoided when tightening the wiring screws. The components should be stored in a dry place with air. If the insulation resistance is less than 1M2 due to long-term storage, they can be dried in an oven at around 200 ℃ or heated by reducing the working voltage until the insulation resistance is repaired. The electric heating tube uses tubular electric heating material as the heating element and high-quality aluminum alloy material as the casing, which is cast and formed into an electric heater. Its application temperature is usually between room temperature and 350 degrees, and it can be widely used in plastic machinery, molds, cable machinery, chemical plants, rubber, crude oil and other facilities.

The method of using electric heating tubes to heat objects is very simple, which is to use the Joule effect generated by the current to effectively convert electrical energy into thermal energy to heat the materials. That kind of heating method can also be divided into two types: direct resistance heating and indirect resistance heating, and the actual requirements are different. If the electric heating tube is directly heated by resistance, the power voltage can be directly applied to the heated object. When there is current flowing through, the heated object itself can generate heat. The object that directly conducts resistance heating must be a conductor with a high electrical resistivity. Because heat occurs within the object being heated, the thermal efficiency is bound to be high.

The heating resistance wire in the stainless steel electric heating tube is in a spiral shape. When the spacing is different, the heating will be different, with close spacing and high heating degree; Long spacing and low heat. When manufacturing stainless steel electric heating tubes, it is impossible for the electric heating wires to have the same spacing. During processing, it is advisable to evenly distribute the resistance wires, especially when winding them, otherwise the heating will not be uniform. The poor quality of the heating wire leads to uneven spacing between wires after compression, which directly leads to uneven heating of stainless steel electric heating tubes.
