Abstract
A pipeline plug includes a pressure head; a seal assembly; a seal expansion ring; a plurality of gripper bodies, a sliding gripper, and an actuator. Each gripper body is coupled to the seal expansion ring. Radial expansion of the gripper bodies supports radial expansion of the seal expansion ring. Additionally, radial expansion of the seal expansion ring supports radial expansion of the gripper bodies. The sliding gripper is slidingly coupled to a radially outer surface of the gripper body.
Claims22
