Coflexip® Flexible Pipe
HIGH PRESSURE FLEXIBLE FLOW LINES
OVERVIEW
When an application calls for flexible flow lines, Halliburton Testing and Subsea often
relies on Coflexip flexible pipe. These flexible lines run from the flow and kill wings of the
surface test tree for the purpose of conveying fluids to and from the surface test tree to
the rest of the surface well test package, kill pumps, or stimulation package.

Coflexip flexible pipe with 2-in., 3-in., and 4-in. inside diameters (ID) are used for
applications up to 15,000 psi to replace hard piping. By using flexible pipe instead of hard
piping, many connections are eliminated, allowing for rig motion and string manipulation.
3
The Coflexip flexible pipe hose has an articulated carcass of spiral-wound stainless steel
covered by an outer thermoplastic sheath. The inner carcass flexes but will not kink or
collapse, ensuring the ID is maintained. The outer thermoplastic sheath is extruded over
the pipe, making it completely leak-proof and resistant to most chemicals.
4
Coflexip flexible pipe, includes two end-fittings complete with lifting/handling collars.
Both the inside and outside of a standard end-fitting is protected against corrosion,
wear, abrasion, and handling.

Features and Benefits
»» Allows for easier and more timely rigging up and rigging down of equipment
1. The thermoplastic inner tube makes
the pipe leak-tight.
»» Hydrogen sulfide (H2S) and carbon dioxide (CO2) limits:
Temperature ºF (ºC)
Fluid Condition
10,000 (690)
236 (110)
CO2 + H2S < 50%
2. The carcass, with interlocked zeta
and flat steel spiral pressure, resists
internal pressure and external
crunching loads.
10,000 (690)
266 (130)
CO2 + H2S < 30%
3. The intermediate thermoplastic
sheath is an anti-friction layer.

CO2 + H2S < 10%
Pressure psi (bar)
»» Compatible with a number of fluids. Refer to OEM guidelines for additional information.
Applications
»» Exploration and appraisal well testing
»» Cleanup and flowback
»» Production and in-line testing (including multiphase flow metering)
»» Extended well testing
»» Early production facilities
4. The double crosswound steel armors
resist axial loads and protect the pipe
from torsional strain resulting from
handling and working conditions.
5. The thermoplastic outer jacket
protects the armors from
external corrosion.
6. The stainless steel outer wrap
(SSOW) protects the pipe from
mechanical impact, abrasion,
weathering, and accidental
mishandling.
