Model No.: CT-CDC Product No.: CT93901 Differential fill-up equipment allows 90% casing fill-up during running-in, reducing surge pressure caused by the piston effect of running in restricted I.D.’s. Use of differential collar provides additional buoyancy by allowing only 81% casing fill-up further enhancing works efficiency. Differential Collar is pressure and cementing plug activated. Circulating can […]
