7 1/16" To 20 3/4" Blowout Preventer Annular BOP With Rubber Core
Annular BOP is offered in a variety of series and pressure ratings. All the annular BOPS are designed and manufactured in accordance to API Spec 16A 3rd edition.
Annular BOP consists of the body, upper housing, dust-proof ring, piston and packing element etc. It can seal all sizes of kelly, drill pipe, drill collar, tool joint, casing and cable, etc. And it can also competely shut off and seal the wellbore when there is not any drilling tools in the well hole.
This BOP, when using accumulators, can allow the 18°/35° non-fine threaded tool joint pass through to carry our snubbing operation.
