Blowout preventers from Hydril Pressure Control were introduced in the 1930s when we developed the first hydraulically operated BOP and the annular BOP. We have made substantial investments in blowout prevention research and development ever since, targeting high-pressure and other critical applications. Today, Hydril Pressure Control provides complete BOP stacks for use in water depths to 12,500 ft.

Hydril Pressure Control Ram BOPsHydril Pressure Control ram BOPs protect personnel and equipment by reliably stopping unexpected surges of oil, gas and drilling mud from the well bore. A Hydril Pressure Control ram BOP has passed API temerature tests to 500° F using fixed-bore rams. |

Hydril Pressure Control Subsea Stack Test ValveThe Subsea Stack Test Valve completes subsea pressure tests in about an hour without pulling the drill pipe and setting a test plug. It also can be reconfigured in the field to be run as a conventional ram BOP cavity. |
