Applications & selection
Typical uses
- Reactor dipping
- Gas sparging
- Liquid addition
Industries: Chemical, Pharmaceutical.
Selecting the right construction
State reactor depth, agitation, insertion length, flange and sparger outlet pattern. Confirm whether the duty requires a lined steel core or a solid PTFE construction.
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.
