- Quad Blowout Preventer
- Stripper Assembly
A coiled tubing BOP is a key part of a well control system. The tubing BOP is often used to control the wellbore pressure in drilling processes like well testing and repairing, in order to effectively prevent blowout accidents and create a safe working environment.
A coiled tubing blowout preventer comprises two parts, the quad blowout preventer and the stripper assembly. Both are designed, produced and tested in accordance with standards of API Spec 16A and API RP 5C7. The BOP interior surface also meets the requirements of NACE MR0175 to be H2S resistant.
