The Bolt Technical Ceramics business of Morgan
Advanced Ceramics (MAC) offers thermal protective sheathing tubes composed
of high performance aluminum oxide (alumina) and aluminum silicate (mullite).
These ceramic tubes protect sensitive thermocouples in high temperature and
highly corrosive environments, such as in reactors employed in chemical processing
Bolt Technical Ceramics, located in Fairfield, New Jersey, supplies these high
performance alumina and mullite thermal protective sheathing tubes, which are
manufactured in MAC’s Haldenwanger facilities in Germany. Protective tubes
consisting of Alsint 99.7 (99.7% alumina) ensure reliable measurement and process
control, even given the stress that can arise due to corrosion and abrasion
combined with very high temperatures (up to 1800°C/3272°F).
Thermal protective tubes comprised of PYTHAGORAS, a mullite ceramic, provide
a more cost-effective solution for slightly lower working temperatures. The
PYTHAGORAS material provides excellent resistance to chemical attack and thermal
shock and is suitable for working temperatures up to 1500°C/2732°F.
The protective tubes are available in gastight or porous versions, in both
SAE and metric dimensions.
