Heating Element For Water Heater
It is a metal tube, along the tube in the center of the central axis of the spiral electric heating alloy wire (nickel chromium, iron chromium alloy) filled with the gap with a good insulation thermal conductivity of magnesia sand, Or ceramic seal. The tube is a special electrical components into electrical energy, because of its cheap, easy to use, easy installation, no pollution, is widely used in a variety of heating occasions, stainless steel heating tube life is very long, generally designed to use Life of more than 10,000 hours.
The heating element is the core of the electric water heater, and the heater heats the liquid to a specific temperature within a certain time.

9.Cap size: 47mm/1.85'' or customized
10. Tube length: 280mm/11.02'' or customized
11. Main application: Liquid heating
The following are a number of criteria that should be considered:
1. The pressure rating and the material of a flange/ screw plug
2. The sheath material of the tubular elements.
3. Watt density, flow velocity, outlet temperature.
4. Liquid level, to ensure that the immersion heater’s heating zone immersed in the liquid.
The sheath material type of it depends on the operating temperature and the corrosivity of the medium within which the heater will operate. The watt density distribution on the surface of a tubular heater is critical for two reasons. First it determines the temperature that a heating element sheath will attain within the conditions that the heater is subjected to. The second reason is that every material has a specific maximum watt density that it can tolerate during its heating cycle.
