DPX-H tail pipe hanger for rotating conditions or static conditions, the hanger is optimized to meet a variety of complex working conditions. Hydraulic sit-hang swivel tail hanger for deep wells and high deviated wells, and in the construction process can rotate and push down action. Hangers through the hydraulic shear cut off the hydraulic cylinder, pushing the connecting sleeve and slip up the upper casing into the annular space, and then down the weight of the drill pipe tail pipe load on the load. After the tail pipe hanger is seated, the tail pipe can still be rotated during well flushing and cementing to ensure the return of cuttings and the uniform distribution of grout.
Features
1. The size and strength match the specifications of the upper casing and tail pipe.
2. Adopt one-body structure, designed with high-torque threaded connection.
3. Righting ring to protect the hanger in the process of entering the role.
4. Tighten the screw to ensure that the cylinder rotates with the body to prevent the seal from failing during rotation.
5. Mechanical locking mechanism to prevent hangers in the process of hanging down in advance.
6. Kava's large contact area reduces the weight of the upper casing to prevent damage to the body.
7. Hardened kava lying in the cone, when drilling can be well protected.
Longitudinal runoff increases annulus transition area, allowing large flow circulation.
9. Large load tapered bearings can withstand larger tail pipe rotation.
10. Cylinder seal can be applied to a variety of well conditions.
11. The body all unobstructed.
