Casing Bushing

General

Casing bushings are cast from high quality alloy steel, heat treated to provide maximum strength and durability. Casing bushings can be installed directly into the rotary table and allow casing string to be rotated during cementing operations. The casing string is aligned with the center of the hole while the string is being run. CUL casing bushings are solid body bushings designed for 17½” to 27½” rotary tables and can accommodate up to 20” tubular goods. CB casing bushings are split body bushings designed to fit directly into 49½” to 22” rotary tables.
Insert bowls are used to accommodate various dimensions casings, thus, one bushing can be used to run multiple casing sizes by interchangeable bowls.
CUL and CB casing bushings are rated working load 500 ton and are designed with 4 tapers.

Used with CMS-XL Slips, casing bushings can handle the longest casing strings currently being set. Also, since these bushings fit into the rotary table, the casing string can be rotated during cementing operations.
