13 5/8"-10,000 Psi Annular BOP Packing Element High Pressure

Annular BOP Packing Element Working Principle:

When wells must be sealed in case of kicks high pressure oil from control systems enters into close-cavity under the piston from the housing oil outlet, to promote the plastic core moving upward along the ball surface, so that bearing tendons move closer to each other to move the rubber between them to the center of wellhead to seal drilling tools or fully seal wellhead. In the opening, hydraulic pressure oil enters into open cavity above the piston from the housing oul inlet, to push the piston moving downwards, so that the plastic will reset with its elasticity, wellhead will be open.
