Casing hanger is used for the connection of casing head and surface casing,there are two types of structure that we can provide:slip type and mandrel type.
1.there are two major types of casing hangers,i.e.the threaded (mandrel) type and the slip-type. 2.the slip-type casing hanger comprises a number of models such as G.W. WD and WE. 3.the model WD hangers are used to connect the casing head with the surface casing .when connected to the casing .the slip teeth of the hanger close tightly around the casing by the use of outer force. 4.the model W hangers are structured to enable the dead-weight of the casing to energize the seal to function. 5.both the model WE and model G hangers operate by energizing the seal manually.
