  • Reliability and life of electric heating coil
    The reliability and life of the electric heating coil are very much related to the type of the core. For example, the core of the main tube which is rolled into a network pipe with a metal mesh is self-filled and very sensitive to the presence of non-condensable gas , So its reliability is poor. In contrast, axial channel heating coils are much more reliable. Reliability also includes predictability and reproducibility of performance. Multilayer network dies are worse in this regard. Its temperature difference has a great relationship with the tightness between the mesh layers, and it is difficult to ensure consistency in the process. And the sintering process of the core (sintered powder, mesh, fiber, etc.), the performance reproducibility is better. The life of the electric heating coil mainly depends on ...
