A single ended electric heating tube, also known as a single ended electric heating tube, is a type of electric heating tube that, compared to a double ended electric heating tube, is connected from one end and generally uses a star connection method. Single head electric heating tube is generally used for mold heating or air dry burning, mainly for mold heating. It is directly inserted into the drilling hole of the mold, and the outlet end is fixed with a gasket to prevent the electric heating tube from moving.
Special attention should be paid to the coordination between the diameter of the electric heating tube and the template aperture when making a single head electric heating tube. If the diameter of the electric heating tube is too large, it will not be able 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.
