Oil 279.4MM Single Ram Bop 70MPA Blow Out Preventer
Oil Rig Blowout Preventer System Features:
1. When there is a well string, the Single Ram Bop can be coupled with a ram assembly to seal the annual space between the casing and tubing string;
2. When there is no well string, the Single Ram Bop can be coupled with full sealing disc assembly to close the wellhead;
3. When there is a tight type damper control device and the situation is urgent, the ram BOP can be coupled with a shear ram cut tubing string in the well, to seal the entire mouth of the well.
(We can provide the BOP: bore size from 7 1/16” to 30”, pressure from 500psi to 20000psi, Not limited in the below list)
