Oil Well Christmas Tree Equipment , Gas Production / Oilfield Christmas Tree API 6A

Oil Well Christmas Tree Equipment, Gas Production Christmas Tree, API 6A

As the most critical equipment for oil production, wellhead and Christmas tree equipment comprise of casing head, tubing head and oil (gas) production tree. This equipment is used to connect casing and tubing, seal the annual space between the casing and tubing, control production wellhead pressure and adjust the fluid oil (gas) wellhead.

The Christmas tee is an assembly of valves, spools and fittings for an oil well, and to design to direct and control formation fluids from the well. It can provide inlet for production tubing strings, including all components above the tubing head adaptor. Christmas tree assemblies can constitute many different kinds of combinations in order to meet any special requirement. Based on their different functions, Christmas trees can be classified into such special Christmas tree as oil production (flowing and artificial lift) Christmas trees, gas (natural gas and various sour gas) production Christmas trees, water injection Christmas trees, thermal recovery Christmas trees, fracturing Christmas trees and acidizing Christmas trees. Different pressure ratings serialize Christmas trees.

The gas production Christmas tree and tubing head are mainly used to produce gas and inject gas. The relative density of natural gas is low and gas column pressure is low, while wellhead pressure is high and liable to leakage regardless of gas production and gas injection. Sometimes natural gas contains corrosive media such as H2S and CO2. Therefore, the gas production Christmas tree calls for rigid requirements on both its materials and its sealing characteristics. For the sake of safety, two gate valves are used on the tubing and casing respectively. Some gate valves to be used on high pressure and ultra-high pressure gas wells are integrated valves manufactured from high quality forged steel.

The pressurization parts of the Christmas trees and tubing spools are made of forged or special smelted forging, so it is high-pressurization safety.

Tiptop supplies wellhead and Christmas tree suitable for onshore and offshore applications to oil exploration, development and production. Design, produce, manufacture, test and quality control are according to API 6A latest edition. The main pressure containing parts of these products are made of forgings or specially smelted low alloy steel, stainless steel, having high bearing strength. Our wellheads are available in 20000psi maximum working pressure and 500 tons maximum suspending capacity, material classes from AA through FF, temperature classes from L through V, product specification levels from PSL 1 to PSL 4 and PR1-2, and are in accordance with NACE Standard MR0175.

Our wellheads have many different kinds of configurations, meeting requirements of all kinds of bore frames and casing programs, providing service in different working conditions. Christmas trees and auxiliary equipments are available at your option. Wellheads also can be designed and manufactured to client’s requirement.
