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.
