Christmas Tree

The christmas tree is wellhead equipment used to direct and control oil & gas from the well. This key piece of equipment for controlling the upper part of an oil & gas well and production adjustment and consists of a casing head, tubing head and oil (gas) tree ontology.

Gas production christmas trees and tubing heads are mainly used to produce and inject gas. While the relative density and gas column pressure is low, well head pressure is high and is prone to leakage. Sometimes natural gas may also contain corrosive media such as H2S and CO2. As a result, gas production christmas trees have more stringent requirements for both materials and sealing characteristics. To ensure a safe operating environment, two gate valves are used on the tubing and casing respectively. Some gate valves, which are used for high pressure and ultra-high pressure gas wells, are integrated valves manufactured from high quality forgedsteel.
