1. Rendimiento
Vida abreviada:
Alta temperatura también dañará el recubrimiento o el enchapado en la superficie del tubo de calentamiento. Para algunos tubos de calefacción con recubrimientos especiales, como recubrimientos anticorrosión, recubrimientos de mejora de la radiación infrarroja, etc., las temperaturas excesivamente altas pueden hacer que el recubrimiento se despegue y falle, afectando aún más el rendimiento y la vida útil del tubo de calentamiento.
Excessive temperature will accelerate the aging of the heating elements (such as resistance wire, etc.) inside the heating tube. Working at high temperature for a long time, the resistance value of the heating element may change, resulting in reduced heating efficiency. At the same time, high temperature will also cause thermal stress between the heating element and the surrounding insulating materials, supporting structures, etc., accelerating the damage of these components, thereby shortening the overall service life of the heating tube. For example, under normal circumstances, a heating tube can be used for thousands of hours, but if it is often operated at excessively high temperatures, its life may be shortened to hundreds of hours or even shorter.
High temperature will also damage the coating or plating on the surface of the heating tube. For some heating tubes with special coatings, such as anti-corrosion coatings, infrared radiation enhancement coatings, etc., excessively high temperatures may cause the coating to peel off and fail, further affecting the performance and life of the heating tube.
