I would appreciate the help of experts: In our plant, there are 4–5 cracks in the ceramic linings of the tees and elbows; moreover, the ceramic material has peeled off at the pipe ends. The gases flowing through these pipes are HCL gas and silicon powder, and the temperature is around 200 degrees. What could be the cause of this? Thank you.

Has there been any change in temperature? At such high temperatures, if the temperature fluctuates, cracks will appear in the ceramics! There might be other reasons as well; experts, please keep answering!

It’s probably due to the temperature difference; high air pressure could also be a factor
