A single headed tube, compared to a double headed electric heating tube, has one end leading out. Single ended pipes can be led out or connected to terminals, and customers can wire them themselves. Single headed tubes are generally used for air drying or heating liquids. Heating liquids can be fixed with threads at the top of the heating tube to prevent movement. Air dry burning mainly refers to the heating of a single head tube in the mold, which is directly inserted into the drilling hole of the mold. It can be a separate straight rod or fixed with a limit plate at the outlet end. According to customer needs, a reasonable stainless steel electric heating tube design can be selected.
