Product Description

Oil Drilling Well Control Equipment Annular Blowout Preventer BOP usually equipped with a large gate with ram-type blowout preventer, which will form a sealed annular space between the pipe string and the wellbore during operation. The well closure can be completed alone, but it cannot be used for several times, and long-term well closure is not allowed.

Annular BOP is compact and can seal any size kelly, drill pipe, tool joint, drill collar, casing or wireline. Sphaericals also provide positive pressure control for pulling the drill rod out of the hole.

Boban supply A-type and D-type annular BOPs; their sizes and models are shown in the table below. A-type annular BOP has bolt cover and wedge cover; D-type annular BOP has threaded head and lock head.
