Special-shaped electric heating tubes are electric heating tubes which are made into required shapes through special processes. Electric heating tube is a kind of sealed electric heating element, with simple structure, reliable performance, and long service life. Currently, electric metal tube-shaped heater has been extensively used in industry and household electrical appliances at home and abroad. In order to improve thermal efficiency, our company has developed single-head heating tube, thread electric heating tube, and special-shaped metal tube-shaped electric heater, which have gained customer recognition and enjoyed good reputation.
