Christmas Tree Instruction


  The christmas tree is the assembly of the valve and the accessories, which is used for the fluid controlof the oil/gas well, and supplying the inlet for the tubing string. The Christmas tree refers to allthe devices on the tubing head and the flange. The Christmas tree could be assembled differently so as tomeet the different requirements, 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 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. 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 christmastree and the tubing heads are forged or cast, with the advantages of high bearing capacity, safety, reliability, etc.
