Handling the heat and the pressure
FS-seals are used against rough surface finish and wider dimensional and geometrical tolerances of casing and tubing.
Sealing materials utilized for wellheads need to withstand pressures as high as 1 034 bar (15 000 psi) and temperatures of 149º C (300º F).
All our FS-seals successfully passed the test according to API 6A annex F PR2 with the following parameters:
- Gas test pressure: 0 to 690 bar (0 to 10 000 psi)
- Temperature: -18 to 121 °C (0 to 250 °F)
- Test medium: Nitrogen gas
- Improved equipment reliability
Extended seal and equipment service life
Reduced installation time, delay and damage
- Protects system from loose materials
FS-seals are available as moulded versions made of SKF Ecorubber-H 85A-b-ED.
