Annular blowout preventer
The annular blowout preventer is divided into the cone rubber core and spherical rubber core according to the structure of the rubber core.
Annular blowout preventer with cone rubber core
The annular blowout preventer with cone rubber core is composed of top cover, shell piston, spherical rubber core and dust-proof coil:
Total exchange of rubber core and HYDRIL
Wearing-resistant belt protection is added structurally, which can prevent and improve the cylinder score incurred due to unbalanced loading of piston
The hoisting ring is strengthened, to hoist the blowout preventer group wholly
The connection way of fixture block is adopted, which facilitates dismounting and rubber core exchange

Annular blowout preventer with spherical rubber core
The annular blowout preventer with spherical rubber core is composed of top cover, shell piston, spherical rubber core and dust-proof coil. Structure and features:
Total exchange of rubber core and HYDRIL
Wearing-resistant belt protection is widened on the basis of the original structure, which can prevent and improve the cylinder score incurred due to unbalanced loading of piston
