Solve problems with long casing strings by connecting a liner to a tieback string with full V0-qualified casing integrity.
High-capacity hydraulic rotating liner hanger
Reduce costs and time by deploying heavy and long liners in drilldown applications with the premium high-capacity hydraulic rotating liner hanger (HCHR). 这种液压式, hydraulic-release hanger is engineered for deepwater and deep land and offshore wells, 即使在高温条件下, with a slip-cone design that distributes axial and radial loading through the hanger body and provides increased hanging capacity over cone-type hangers.
An antipreset mechanism prevents the hanger from being set before the hydraulic setting mechanism is activated, and fully pocketed slips reduce running and rotating interference in drilldown applications. When enough pressure has been applied to the system and the slips have been set, the high-performance bearing enables rotation during cementing to improve cement integrity.
