Teach you how to distinguish the quality of heating tubes

Jan 29,2024

1、 Insulation: The main factor affecting the insulation of the heating tube is the sealing process of the heating tube.
2、 Leakage and flow generation: mainly related to the temperature during the use of the heating tube, the pressure generated by the use of the heating tube, and the length of the heating tube. An important inspection indicator for high-temperature heating tubes.
3、 Power accuracy: mainly related to the quality of the resistance wire and the manufacturing process level of the factory. Before mass production, it is necessary to conduct temperature coefficient experiments to determine the qualified power scale of cold resistance.
4、 Lifetime: The lifespan of a heating tube is not only related to the quality of the resistance wire, but also to factors such as the quality of magnesium oxide powder and the selection of resistance wire diameter. When selecting the diameter of the resistance wire, it is necessary to calculate the surface load of the resistance wire to meet the service life requirements.
5、 Heating intensity: The main factors affecting the heating intensity of the heating tube include the thickness of the insulation layer, the quality of the insulation layer's raw materials, the length of the heating tube, the radius and number of twists and turns.
