Hydraulic Operated Annular Blowout Preventer Wellhead Drilling Oilfield BOP Compact

API 16A Bolted Cover Annular Type Blowout Preventer for Wellhead Drilling

The blowout preventer is designed with hydraulic opening and closing of the gate, and can easily and quickly replace the gate.

The closing pressure provided by the control system is used to close the blowout preventer gate and can also be used to open the end cap. When used to open the end cap, the closing pressure of the control system causes the gate to close. After removing the end cap bolts, use the pressure of the control system to open the end cap. After the end cap is fully opened, the gate can be removed from the body. At the top of each gate, there are threads for installing suspension buckles, which can be installed to facilitate the lifting of the gate.

The opening pressure provided by the control system is used to open the preventer gate and can also be used to close the end cap. When used to close the end cap, the opening pressure of the control system causes the gate to open. After replacing the gate, use the opening pressure of the control system to close the end cap. Before the gate is moved into the blowout preventer, it is first pulled out close to the end cap. This ensures that the gate does not block the vertical through-hole of the blowout preventer, avoiding friction with the drill pipe inside the well. After the end cap is completely closed, install the end cap bolts firmly.
