API 6A Certified Well Head Equipment, Annular BOP, 2,000psi ~ 15,000psi, 7 1/16”~ 21 1/4"
Wellhead equipment Annular BOP :
Annular BOP is usually matched with ram BOP, and also, can be used separately, used to seal a variety of shapes and sizes of the kelly, drill pipe, drill pipe sub, drill collar, casing etc; When there is no drilling tool, can be completely close the wellhead. With the conditions of using buffer energy storage,Through 18°/35°no thin buckle butt welded joint, forced tripping.
The annular BOP is only a transitional equipment in shut-in,not sealing with a long time; should use the ram BOP when sealing well for a long time.
