Packardís Inside Blowout Preventer (IBOP) is used to provide shutoff of backflow during periods when the drill string is open. The valve is held with the dart in the open position to allow stabbing during backflow. After stabbing the flow is shut off by turning the release handle. The stab body is removed and the drill string can be reconnected to re-establish pressure stabilization. The valve can then be removed and returned to its ready state or it can be left in the drill string to ensure downward flow only.
Features and Benefits
The Packard International IBOP is manufactured and tested in accordance with API Specification 7-1 with NACE compliant internal components. The integral seat design minimizes repair time and costs.
The Packard International IBOP can be supplied with any API connection, including many proprietary threads supplied by licensed vendors and OEMs.
High and Low Pressure Sealing
High and low pressure sealing is assured by Packardís unique elastomer and metal-to-metal sealing systems. The IBOP is available in pressure ratings up to 15,000 psi working (22,500 psi test pressure).
Packard Internationalís IBOPs are designed for even the harshest drilling conditions; however, it is suggested that parts most subject to wear and tear be replaced regularly.
