Abstract
An air swivel ring includes a non-rotating member having an air inlet, a rotating member having an air outlet, and a split seal having a first sealing surface and coupled to one of the non-rotating member and the rotating member so that the first sealing surface on the seal is disposed proximate a second sealing surface on the other of the non-rotating member and the rotating member.
Claims20
A method for assembling an air swivel ring, the method comprising:
- providing a non-rotating member of the air swivel ring, the non-rotating member comprising an air inlet and a first seal groove;
- providing a rotating member of the air swivel ring, the rotating member being configured to mate with the non-rotating member, to rotate relative to the non-rotating member and comprising an air outlet and a second seal groove that corresponds to the first groove of the non-rotating member, wherein the second seal groove is radially juxtaposed to the first seal groove;
- attaching a seal assembly to one of the first and the second seal grooves, wherein the seal assembly is configured to sealingly engage the other of the first and the second seal grooves when energized by air received from the air inlet;
- and
- connecting a bearing system to one of the non-rotating member or the rotating member for supporting a rotation of the rotating member.

A method of installing a seal system for providing compressed air to a drill string internal blowout preventer (IBOP), the method comprising:
- installing a rotating member of the seal system on a drill string such that the rotating member rotates with the drill string;
- providing a non-rotating member comprising an air inlet and a first seal groove;
- connecting a first pipe to the air inlet of the non-rotating member and configured to provide the compressed air in the first seal groove;
- mating the rotating member with the non-rotating member, the rotating member comprising an air outlet and a second seal groove that corresponds to the first seal groove of the non-rotating member, wherein the second seal groove is radially juxtaposed to the first seal groove such that the compressed air from the first seal groove is received at the second seal groove;
- connecting a second pipe to the air outlet of the rotating member and configured to receive the compressed air from the second seal groove, the second pipe being configured to rotate together with the rotating member and the drill string;
- and
- inserting a seal assembly in one of the first and the second seal grooves, wherein the seal assembly is configured to sealingly engage the other of the first and the second seal grooves when energized by the compressed air,
- wherein the first pipe is detachable attached to the non-rotating member and the second pipe is detachable attached to the rotating member.
