A single head heating tube, compared to a double head electric heating tube, has one end leading out. The single head heating tube can be led out or connected to a terminal, and the customer can wire it themselves. Single head electric heating tubes are generally used for air drying or heating liquids. The heating liquid 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 electric heating 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.
It should be noted that when making a single head electric heating tube, the fit between the tube diameter and the template aperture should be considered. If the diameter of the electric heating tube is too large, it will cause the stainless steel heating tube to be unable to fit into the hole, and the expansion factor of the heated tube will be considered, which will bring inconvenience to later maintenance; In addition, it is necessary to consider that the pipe diameter should not be too small, and there should not be too much space reserved between the hole wall, which will affect the heat transfer effect and service life of the electric heating tube. So when placing an order for a single head heating tube, it is important to pay attention to the diameter of the tube and clarify whether it is a positive or negative tolerance before placing an order.
