Swivel
A swivel is a mechanical device used in drilling rigs to suspend the weight of the drillstring while allowing it to rotate. It also facilitates the transfer of high-pressure drilling mud between the rig’s circulation system and the drillstring.

In the drilling context, swivels are crucial components that connect the hoisting system to the drillstring. They allow free rotation of the drillstring beneath them while bearing the load of the entire string. Swivels are designed to withstand extreme axial forces and facilitate the uninterrupted flow of drilling mud at high pressures, which is essential for cooling the drill bit, removing cuttings, and maintaining wellbore stability. Advanced swivel designs improve durability, reduce maintenance needs, and ensure consistent performance in challenging drilling environments. Beyond drilling, swivels find applications in other oil and gas operations requiring rotational flexibility and load management.
