Duplex 2205 Hydraulic Control Line Tubing
Control line is normally used to operate surface controlled
subsurface ety valves. Tiptop specializes in providing control
lines that can meet the specific requirements of each customer. The
control line with ASTM specifications can be offered in wide range
of metallurgies. Encapsulated control line is also available which
can improve the crush and abrasion resistance of the control line.
Encapsulated control line is available in several configurations
and materials to suit the customers' special requirements.
• Control Line Materials - 316SS, 316L, Nickel Alloy 825, Nickel
Alloy 625, 2205 Duplex, 2507 Duplex, and Other Encapsulation
Materials.
Control line uses seamless welded stainless steel, duplex and
nickel alloy tubing to protect electrical and optical components
from the pressure and corrosive effects of the downhole
environment. Our company specializes in producing Capillary
tubing(Control line tube) , is your reliable supplier.

This product is mainly used to inject chemical reagents to oil and
gas wells. The upcoming 3/8 "hydraulic control line connected to
the downhole chemical injection valve, the cleaning chemicals from
the ground into the underground pipe through a certain
concentration of 3/8 hydraulic control pipeline and chemical
injection valve, fouling effective detachment of tubing, ensure the
normal production of oil and gas fields. The utility model can also
be used for the pressure control of the ground ety valve and other
ground valves, and various connecting pipelines of the instrument
control system of large-scale oil drilling and oil production
large-scale equipment.
Stainless steel coiled tubes is widely used in oil drilling,
shipbuilding, aerospace and petrochemical oil refining equipment,
spiral wound heat exchanger and chemical industry of cold
treatment, gas transmission pipeline, fluid pipeline, steam
insulation pipe cable, stainless steel heat tracing coiled tubes,
high pressure fluid pipeline, stainless steel thermal insulation
pipe cable, anticorrosive stainless steel pipe cable and umbilical
cord protected by pvc sheath pipe and cable industries.
