Materials used for glass-lined steel repair
Polytetrafluoroethylene (PTFE) – Plastic material inert to virtually all chemicals– Superior non-stick properties– Material used for nozzle repair sleeves for glass-lined
reactors Tantalum
– Tough, ductile metal– Used in corrosion resistant applications in environments
no other metal can withstand (resistance very similar to glass)
– Often used with glass-lined steel reactors as patches, dip tubes, piping and overhead condensers.
