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 be established at any time while running in. Dropping a ball converts the differential valve to a regular back-pressure valve. When Shoe and Collar are run together, dropping one ball converts both units.
- Easily convertible to conventional valve- Converted to conventional one-way check valve by dropping a ball and pressuring up to release the upper flapper.
- Various ball size – conversion ball is available in various size i.e 1-1/4” , 1-1/2” , 1-3/4”.
CEMENTING MANIFOLD
Cementing Manifold is attached to the top joint of the Running in String. This will allow a pump down plug to be released from the surface without breaking a connection or hammer union. An elevator lifting neck is included at the top, and a heavy duty swivel at the lower end to allow reliable rotation […]
