Model D Annular BOP
· Simple structure, less maintenance.
· Using a spherical rubber sealing element.
· Low one-piece height to save installation space.
· Large volume of spherical rubber sealing element, long service life.
· Wide sealing range, BOP can seal different sizes and shapes of pipe string, drill tools and wireline/cable not more than BOP bore size in diameter.
· Quick and reliable hydraulic drive. |
