Precautions To Prevent Leakage Of Single-Head Tube

Tubular electric heating elements are made of metal tubes (including stainless steel and copper tubes), and spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) are filled with compacted magnesia sand along the central axis of the pipeline, which has good insulation and thermal conductivity. Both ends of the nozzle are sealed with silica gel, which can heat air, metal molds and various liquids.

  The general explanation is the carrier that converts electrical energy into heat energy. The usual practice is to place a heating wire in the metal pipe fittings, fill the insulation modified magnesium oxide powder around the heating wire, and fix the heating wire. For heat transfer effect, pay attention to several points when using single-head tube to prevent leakage.

 1. During the storage and use of the single-head tube, attention should be paid to the waterproofing of the terminal to prevent problems such as electricity and short circuit from entering the electric heating tube.

  2. When the single-head tube is a solid object at room temperature, such as asphalt, paraffin, etc. The voltage should be reduced when the heating is started, and the voltage should be increased to the rated voltage when the solid melts.

  3. Distinguish the single-head tube for heating liquid and heating air. Prevent the boiling water from drying out. When boiling water to heat and dry, the heating part should be completely put into the water to prevent the heating tube from overheating, bursting and leaking.

  4. When electric heating tubes are used for air heating, attention should be paid to the even arrangement of electric heating tubes. The advantage is to ensure that the electric heating tube has enough and uniform heat dissipation space, as much as possible to ensure the air flow, and improve the heating efficiency of the single-head tube.
