-- Ceramic tubes are used when conditions exclude the use of metal, either for chemical reasons or because of excessive
temperatures.Their main applications are between 1000 and 1800°C.
-- Ceramic tubes should be mounted in a hanging position above 1200°C to prevent distortion or fracture due to bending stresses.
