Video Description

2018 new 99% silicon nitride heat resistant ceramic tube

Product Description

Riser Tubes offer long service lifetimes, due to good thermal shock resistance and good corrosion resistance. This extended service life translates to longer intervals between cleaning and less production downtime for tube removal and replacement.

 

Features and Benefits

 • Gas-tight

• Long life >12 months

• Unaffected by corrosion

• No melt contamination

• Can be used in melts containing sodium and strontium

• Resists build-up of dross

• High temperature resistance up to 1,300°C

• High thermal shock resistance

• No preheating required at operation temperatures below 900°C

• Easy cleaning of bake-on • Best price/performance ratio
