CASING BUSHING SPLIT TYPE for 27 1/2
When the casing is run into the drilled hole it is desired that casing string must be aligned with the center of the hole and casing can be rotated during cementing operations. This ensures placement of cement slurry uniformly around the casing for a good cement bonding between casing and borehole. Autobahn Industries developed Model ABSCB Casing Bushing, Model ABSCB Casing Bushing is a split bushing and is also interchangeable with varco casing bushing.
Different sizes of insert bowls can also be fitted in these bushings to lower many different sizes of casing pipes.
