Product Description
IBOP Working Pressure 70 (35) MPA | OAL 711mm (28 inch)
Product Overview
The IBOP (Inside Blowout Preventer) is a non-return check valve, also known as Gray Valve or BVR, designed as a back pressure valve for drill strings. Its primary function is to prevent uncontrolled well flow up the drill string during operations.
Key Features and Benefits
- High pressure rating for demanding drilling conditions
- Reliable sealing mechanism for effective blowout prevention
- Simple application and operation for efficient field use
- Prevents backflow during lifting operations
- Allows controlled fluid discharge when needed
Operational Principle
During drill tool lifting operations, the IBOP's open position allows backflow to facilitate installation. In case of a blowout, the valve can be quickly closed using a relief rod to stop backflow. Surface pumps can then be used to discharge the IBOP and drill string, achieving blowout prevention through controlled fluid regulation and pump circulation.
