Casing Bushings play a critical role in ensuring that the casing string aligns with the center of the drilled hole and can be rotated during cementing operations. This alignment is essential for uniformly placing cement slurry around the casing, facilitating a strong bond between the casing and borehole. We offer a comprehensive range of Casing Bushings, including Square Type and Round Type, suitable for 27½”/37½” Rotary Tables. These Casing Bushings are equivalent to and interchangeable with NOV products and are manufactured in strict accordance with the latest API-7K specifications. They can be used with NOV, Wirth, Drillmec, or any other API Monogrammed Rotary Table.
