 When installing the casing in the oil well, the lower casing with smaller diameterneeds to be installed with hanger after the upper casing has been fixed. An important function of the hanger is to help connect the upper and lower casing with the different diameter (ie, hanging operation). When hanging operation, the slip of the hanger should be effectively connected with the upper casing and be subjected to the weight of all the lowercasings with smaller diameter.


 Main Features

1. Double cylinder structure (with staggered position of the slip) can increase the success rate of seat hanging operation;
2. Hydraulic control operation, easy to operate;
3. Feeding assembly is mainly to send the tail pipe to the required depth, rotate forward.Screw the nut with left-hand threads (left-hand buttress thread) out the milling joint with left-hand thread, raise the drill string to trip out the upper connect rod, top sub, back-connect barrel cover and so on from the well. 
4.The hollow rubber plug and the drill pipe rubber plug are all designed with a locking mechanism. They can prevent back pressure after the cement is injected and have good drillability.
5.The sealing joint can be tripped with the feeding tool out from the well to save the drilling  time of the sealing core;
6. Sealing joint adopts double seal structure, which of the sealing effect is better;
7. Reverse operation is easily. Raise the WOB for 5~10t, and then rotate forward to reverse. 
8. The hanging assembly is equipped with a centering ring on both the upper and lower ends, which can ensure the correcting effect and can effectively protect the cylinder and slip.
