U Shape Air Electric Tubular Heater

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.
