Christmas Tree & Tubing Heads
The Christmas tree is the assembly of the valve and the
accessories, which is used for the fluid control of the oil/gas
well, and supplying the inlet for the tubing string. The Christmas
tree refers to all the devices on the tubing head and the flange.
The Christmas tree could be assembled differently so as to meet the
different requirements. The Christmas tree could be used for oil
exploration, gas exploration, water adding, compression fracture,
acidification, etc. The different Christmas trees are with the
different pressure grades.
The Christmas tree and the tubing heads are mainly used for gas
exploration and adding. Because the natural gas is with the low
relative density and adding pressure, while the wellhead is with
the high pressure and flow rate, it would be easy to leak.
Sometimes, there's H2S, CO2 and other corrosive medium in the
natural gas. It would have the more strict requirements on the
sealing capacity and the sealing materials of the Christmas tree.
Thus, the tube and the sleeve should be with double valves. The
valves should be forged by the best-quality steel for the
high-pressure or extra-high-pressure gas well.
The main bearing pieces of the Christmas tree and the tubing heads
are forged or cast, with the advantages of high bearing capacity,
safety, reliability, etc.
