Swivel is a mechanical device used on a drilling rig that hangs directly under the traveling block and directly above the kelly drive, that provides the ability for the kelly (and subsequently the drill string) to rotate while allowing the traveling block to remain in a stationary rotational position (yet allow vertical movement up and down the derrick) while simultaneously allowing the introduction of drilling fluid into the drill string.
Parts: bail, Gooseneck, upper shell, body, lower shell, swivel stem, shaft, sealing system etc.
Main Mechnical Feature
1. As per API 8C standard;
2. Swivel and Kelly spinner are combination;
3. High strength steel ensure the service time and capacity;
4. High pressure drilling fluid sealing system;
5. With keyless connection adopted between spinner and central pipe of swivel
