RockySea Petro Casing Head And Tubing Head



RockySea Petro casing heads strictly conform to the International standard, and are among the most reliable oilfield casing heads. Usually, the casing head lies at the bottom of the wellhead and X-mas tree equipment. It supports the drilling wellhead, the casing head spool, the X-mas tree and completion equipment. The casing head is used to connect the casing string and packing off the next casing string. The connecting type includes slip-on weld, thread and slip lock. The casing head made by Sabjack is suitable for standard/H2S services. The working pressure is up to 20000psi and temperature ranges from -60 ℃ to 390℃.


Description 

Casing head is mainly used to fix the wellhead of the drilling well, connect the downhole casing string, and reliably seal and control the annular space between the casings. It is an important component of oil &gas wellhead equipment in the oilfield.

1.Structural features

The pressure bearing shell is made of forged alloy steel with high strength, few defects and high pressure bearing capacity. The mandrel hanger is made of forgings, which leads to high bearing capacity and reliable sealing. All metal parts of slip hanger are made of forged alloy steel. The slip teeth are carburized and quenched. The unique tooth shape design has the characteristics of reliable operation and high bearing strength. The valve equipped adopts a non-rising stem, which has small switching torque and convenient operation. The slip type hanger and mandrel type hanger can be interchanged.

The casing hanging mode: slip type, thread type and sliding welding type.

2.Casing head type:

Single stage thread type: it can process all kinds of casing thread and connected with the surface casing through the pin*pin nipple, which is quick and convenient to install. The production casing can be suspended by mandrel or slip.

single stage thread type casing head

Split double stage type: it can hang three layers of casing, the surface casing can be threaded or sliding into welding type, and the technical casing and production casing can be of slip type or mandrel type.



Slip type bottom connection casing head: the upper locking screw is used to make the slip tooth clamp the surface casing. And BT type casing sealing ring is provided, which is firmly connected, convenient and reliable.
