Tubular Finned Heater Type U | Electric Heat Tube

Electric tubular heater material is stainless steel (material can be changed according to customer requirements and use environment), the highest medium temperature of about 300℃. Suitable for a variety of air heating systems (channels), can be used as a variety of ovens, drying channels and electric furnace heating elements. Under special high temperature conditions, the tube body can be made of stainless steel 310S.

Dry-fired electric heating tubes and liquid heating tubes are still different. Liquid heating pipe, we need to know the liquid level height, whether the liquid is corrosive. The liquid heating tube is necessary to be thoroughly immersed in the liquid during the operation process to avoid the appearance of dry burning of the electric heating tube, and the outer temperature is too high, resulting in the heating tube bursting.

If we use the usual softened water heating pipe, we can use the usual stainless steel 304 raw materials, the liquid is corrosive, according to the size of the corrosive can be selected stainless steel heating pipe 316 raw materials, Teflon electric heat pipe, pipe and other corrosion resistant heating pipe, if it is to heat the oil card, we can use carbon steel raw materials or stainless steel raw materials, carbon steel raw materials cost is lower, It will not rust in heating oil. Regarding the setting of power, it is usually recommended that customers do not exceed 4KW per meter of power when heating water and other media, it is best to control the power per meter at 2.5KW, and do not exceed 2KW per meter when heating oil, if the external load of heating oil is too high, the oil temperature will be too high, prone to accidents, must be careful.

Technical datas for tubular heater

1. Tube material: stainless steel 304,SS310
2. Tube diameter: 6.5mm,8.0mm,10.7mm,etc.
3. Power: customized
4. Voltage: 110V-230V
5. can be added the flange,different tube the flange size will be different
6. Shape: straight,U shape,M shape,etc.
7. Size: customized
8. package: packed in the carton or wooden case
9. the tube can be choose whether need to anneal

Key Selection Parameters:

Power and Voltage: Selected according to the heat load and power supply (e.g., 1kW, 1.5kW, 3kW).
Tube Diameter and Material: Common diameters are Φ6mm-Φ30mm; stainless steel (SS304/SS316) offers corrosion resistance.
Fin Design: Material (aluminum/stainless steel), spacing, and thickness affect efficiency.
Connection Method: Terminal box or lead wires, adaptable to the installation environment.

Application

Dry-fired electric heating tube, stainless steel heating tube for oven, single head heating tube for mold hole heating, fin heating tube for heating air, different shapes and power are planned according to customers’ requirements.

The power of the dry fired tube is normally set to not exceed 1KW per meter, and can be increased to 1.5KW in the case of fan circulation. From the perspective of thinking about its life, it is best to have temperature control, which is controlled within the acceptable scale of a tube, so that the tube will not be heated all the time, beyond the acceptable temperature of the tube, no matter what the quality of the stainless steel electric tube will be bad.
