Casing hangers are devices that allow casing to be set in the well bore during the drilling phase of an oil or gas well. There are two basic designs of casing hanger, slip-type or mandrel. The slip-type is the conventional and most commonly used. The mandrel-type is normally used when special needs arise during the building of the well. Both allow for the Tens of Thousands of pounds in weight of the casing string weight to be transferred from the derrick of the drilling rig to the load shoulder in a casing head or spool. A Casing Hanger performs the following functions:
In petroleum production, the Casing Hanger is the subassembly of a wellhead assembly which supports the casing string when it is run into the wellbore. It serves to ensure that the casing is properly located. When the casing string has been run into the wellbore it is hung off, or suspended, by a casing hanger, which rests on a landing shoulder inside the casing spool. Casing hangers must be designed to take the full weight of the casing, and provide a seal between the casing hanger and the spool.
There are mainly two types of casing hangers, the slip type and the mandrel type(threaded type or core shaft). The Slip-type casing hangers include G-type, W-type, WD-type, WE-type, etc. The WD-type casing hanger is used to connect the casing head and surface casing, which the slip tooth hold casing under external force. The W-type casing hanger adopts self-weight energized sealing structure. The WE-type casing hanger and G-type casing hangers feature manually-energized sealing structure.
All of our casing hangers are fully designed, manufactured and tested in accordance with API 6A standards. Available with various sizes and working pressure ranging from 2000PSI to 20000PSI. The most common size of casing hanger produced by us is 13-3/8" with about 500 sets alone annually. We can also design and produce many types of casing hangers according to customers' specific requirements.
