●Shell of pipe: Shell with high-purity quartz glass tube off hydroxyl.To 1200 degree heat.For small and resistance to thermal expansion coefficient changes.After lamp ignition,the surface temperature reaches 800 degrees on the tube surface,0～4 degrees pouring water tube will not burst.

●Heating Element:carbon fiber heater is a pure black body material made of polypropylene fiber composite with rayon fiber carbonized. Its light weight. High modulus strength high.Strong far-infrared radiation.Can effectively guarantee the life time of heat tube.

●Lamp head:Both ends of the lamp using high-purity 95# alumina ceramic.Seal using high temperature adhesive.In the high humidity (RH95%) special circumstances make the heat tube imported silicon adhesive sealing.
