套管头AB-22

AB-22/ AB-29：

The AB-22/AB-29 casing head is designed with a 45 º main bearing shoulder to support the weight of the casing string transmitted by the casing hanger. This design can avoid damage to the sealing surface by drilling tools and prevent wedging of the wear-resistant sleeve and pressure test plug. The side outlet is threaded, but bolted connections can be provided as needed. The bottom can be welded or threaded to connect the sleeve.
The AB-29 casing head has the same reliable design as the AB-22, but the bearing shoulder depth of the AB-29 casing head is greater than that of the AB-22; After assembly with AB-29 casing hanger, it is suitable for drilling deep wells.
