- Repair Procedure
Duro-Bond FEP sheet lining can be shop or field repaired. The repairs to defective or damaged areas in the sheet lining are accomplished by cutting out the faulty area, grinding or grit blasting the substrate surface, preparing a piece of sheet of the same dimension, cementing it into position and subsequently welding the joints as described under Application. The repaired area is then inspected and spark tested to insure lining integrity.
- Testing Methods
All lined surfaces are visually inspected for surface defects. Any special dimensional tolerances required after lining are also checked. All lined areas are then spark tested for pinhole leaks using a dielectric spark tester adjusted to 1 0,000 volts. The tester is moved constantly and quickly over the lining surface to prevent a burn through.

- Chemical Resistant
- Service Temperature
FEP fluorocarbon resins withstand continuous service temperatures as high as 205°C (400°F). When bonded to a substrate, the maximum recommended service temperature for Duro-Bond FEP sheet lining is 110°C (230°F) on a continuous basis, 120°C (250°F) on an intermittent basis
