4. According to the structure of the body.
According to the structure type of the body, the monomer sleeve head (a hanger is installed in the body), and the combined casing head (a plurality of hanger in the body);
R&T Group offers casing hangers, which can be sorted into thread (mandrel) type and slip type. Slip casing hanger includes G type, W type, WD type, WE type and etc.
