Carbon fiber quartz electric heating tube, its life (continuous point burning) â?¥ 6000 hours or more, in frequent start-up, shutdown and long-term continuous work, the heating element has no oxidation and breakdown, the heating light color is uniform, and the inside and outside of the pipe wall are clean. Unlike metal heating elements, it completely avoids the generation of electromagnetic fields. The product encapsulation material is made of high-purity dehydroxy-hydroxy quartz glass tube with very low thermal expansion coefficient and high thermal stability. It can withstand severe temperature changes without bursting (the quartz tube is heated to 1500 °C, and it is not rapidly put into 20 °C water). Burst). Quartz glass is a good acid-resistant material (except hydrofluoric acid), which is 30 times that of acid-resistant ceramics and 150 times that of stainless steel (nickel-chromium alloy). We are a factoy in producing Carbon fiber heaing lamps more than ten years. If you are looking for this items, please feel free to contcat me for a quotation.
