Applications & selection
Typical uses
- Boiler house valves
- Refinery pumps
- Steam service
Industries: Power plants, Refineries, Steel mills.
Selecting the right construction
Provide section or ring dimensions, equipment type and medium. Review compatibility for oxidizing chemicals and confirm the duty-specific operating limits.
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.
