Completion Seals
This article describe the categories and types of seals used for completion equipment.
2 categories of seals:
- static seals where the sealing surfaces do not move relative to one another,
- dynamic seals where the sealing surfaces do move relative to one another.
3 types of seals:
- polymeric or resilient seals. Which are either elastomeric (natural or synthetic rubbers) or plastomeric e.g. Teflon.
- metal-to-metal seals.
- metal encapsulated polymeric seals (combination of the first two types).
