Tubing usually is a head at both ends of the large flange with Stone, first installed in the casing on the flange, for the hoisting of tubing string and sealing layer tubing string casing and tubing between the annular space. It is the first Stone tubing and tubing hanger from.
The function of tubing head
⑴ hoisted hole tubing string;
⑵ seal the tubing and casing annular space;
⑶ casing next to the first, then on the oil trees provide transition;
⑷ four-way through the first tubing on both sides of the mouth, into the casing and completion of wells, such as washing operations.
Tubing Hanger
The hoisting of the tubing string and bearing oil seal between the tubing and casing annular space, and equipment. Tubing Seal way for the hoisting of the hoisting device with the tubing is connected by tubing sit tubing gravity linked to the pipeline within the sealed Stone Cone, the efficiency of operation, for wellhead fast, safe and therefore is in Sham Tseng, the use of conventional wells by the ordinary way.
I tubing produced by the first four-way fully consistent with API 6A requirements, or ontology adopted after forging the casting special smelting production, high pressure, safe and reliable. The export side of a pipeline to plant silk thread-and-two and display a silk-lateral export processing one 1/2LP within the thread.
