Further Notes
Technical Appendix
Where there is internal pressure or atmosphere in the furnace, then dense products are required. Alumina tubes or Mullite tubes would be good solutions for these applications. Dense Alumina or Mullite furnace tubes are a little more prone to thermal shock than porous versions, so heating rates need to be carefully controlled to prevent cracking.
Our ceramic tubes are extensively used as furnace tubes in extreme working environments. For example principle laboratory/analysis furnaces such as Carbolite, Leco and Lindberg. The tubes are normally supplied as dense mullite (EM60) or alumina (EA998) for these applications.
Porous ceramic tubes are also used to support wound elements for heating larger furnaces and Kilns. Ceramic tubes are ideal to provide lead outs for electrical cables. Also for temperature measurement or as burner holes in Gas and oil fired Kilns. Anderman also supply custom ceramic burner components in Alumina or Silicon carbide.
FAQs
Your questions answered
What size of ceramic tube can you supply?
We supply tubes from 0.125mm to 1m outer diameter, with lengths up to 5m. Standard sizes are held in stock; custom dimensions are available on request.
Can you machine custom features into tubes?
Yes. Custom features include flanges, angled cuts, drilled holes, machined ends, slots and glazed surfaces. Send us your drawing and we'll work to your specification.
Which material suits high-pressure or atmosphere-controlled furnaces?
Dense materials are required where there's internal pressure or controlled atmosphere. Alumina or mullite tubes are typically specified — but heating rates must be carefully controlled to prevent cracking.
