Single head tube is commonly used for mold heating or air dry firing, 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.
Single head electric heating tube, also known as single end electric heating tube or single head tube, is a type of electric heating tube that has one end of the wire and is usually connected in a star shape, compared to a double head electric heating tube. Surprisingly, when making a single headed tube, consideration should be given to the fit between the diameter of the tube and the aperture of the template. The diameter of the electric heating tube is too large, which makes it impossible to fit it into the hole, and the expansion factor of the heated tube is also taken into account, which brings inconvenience to later maintenance; Additional considerations should be taken into account that the pipe diameter should not be too small and there should not be too much space left between the hole wall, which may affect the thermal conductivity and service life of the electric heating tube.
