FRP failure in Nitration process
FRP failure in Nitration process
(OP)
Dear all,
we select FRP equipment working in nitration process, and some failure occured during operation, especially for flange face and agitator part.so, does anyone have relative practical experience about this kind of equipment in nitration process?
is it necessay to update materials to replace FRP, or maybe much more focusing on FRP fabrication and operation process?
photo shows detail information in flange face.
Thank you.

A lot of the time glass spalling has to do with stress to the nozzles. Over torqueing the bolts or incorrect gasket choice. Heavy agitator loads can cause nozzle movement and that can break the nozzles.
Chemsoft or Teflon Envelope gaskets seal well with minimal bolt toque required.
