Applications & selection
Typical uses
- Corrosive fluid piping
- Plant pipe spools
Industries: Chemical, Petrochemical, Fertilizer.
Selecting the right construction
Provide spool length, bore, flange orientation and a piping drawing. Confirm the lining material and service rating; the catalogue's FEP-lined pipe specification lists service up to 180°C.
Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.
