Wellhead Annular BOP 13 5/8" x 10000psi
API 16A Blowout Preventer Oil Well BOP
Introduction of the Annular BOP
The annular blowout preventer is divded into the tapering packing unit annular BOP and spherical
packing unit annular BOP according to the structure of the packing unit,
Annular Blowout Preventer with spherical rubber is composed of five parts as upper housing, body,
piston, spherical rubber and anti-dust ring
Annular Blowout Preventer with tapered rubber is composed of seven parts as upper housing, wear
plate, body, piston, tapered rubber, anti-dust ring and supporting cylinder.
Feature of Tapering packing unit annular BOP
-The tapering packing units are exchangeable with the hydril's
-The added wear-belts to the original design can prevent and improve the cylinder-grinding due to unbalanced loading.
-The fortified rings can lift the whole BOP Stack
- Screws connection type is convenient for assembling/disassembling and exchange of the packing units.
Feature of spherical packing unit annular BOP
- The spherical packing units are exchangeable with the shaffer's
- The added wear-belts to the original design can prevent and improve the cylinder-grinding due to unbalanced loading.
