API 6A Casing head
Oil well Casing head
Well head equipment
With the design of versatile straight-bore, the casing head and casing spool can be equipped with mandrel hanger and slip hanger, to handle any emergency effectively while the flange housing remains unchanged. The improvement of the structure simplifies the operation procedures and saves operating time
-Straight-bore design 45 degree shoulder with large load capacity
-Side outlet connection Pipeline thread side outlet Threaded flange side outlet VR thread
-secondary seal mechanism is designed on the bottom. The casing can be cut on site during tubing installation so as to accommodate the seal height.
-Slip casing hanger and mandrel type casing hanger are interchangeable.
-Connection types between casing head and surface casing including welded bottom connection,threaded bottom connection and slip bottom connection
