Fiberserts represent a superior technique with over 25 years proven
service for providing corrosion protection of both the coupling "J"
section and pin ends of lined tubing. Fiberserts are attached to
the coupling end of the liner. The system is sealed at the time
of make-up with Permitek, a proprietary plant-applied mastic.
Fibersert Advantages
- Provide multi-thread tolerance at make-up
- Prevent liner damage at pin end due to over torque
- Eliminate damage from minor turning of the coupling during make-up
- Provide virtual total isolation of the "J" section and pin ends from corrosive fluids
- Provide full protection of the "J" section from wire line and tool damage
- Eliminate "J" section turbulence
