Flexible pipe: What it really is and how it solves so many problems

"Flexible pipe" isn't just a fancy
advertising name for another kind
of hose. Coflexip flexible pipe
actually has the pressure rating,
crush strength and safety factors
of rigid API steel pipe, and the
Z-section withstands high
internal
and
external
pressures, resists kinking.

reinforced

ratings, it actually has a smaller
bending radius than the same size
hose.
By
combining
these
two
qualities, Coflexip solves a host of
drilling and production problems.
Flexibility saves in offshore
construction
Since 1972, over 1,000,000 feet of
Coflexip lines have been installed
for production systems. Flexibility
makes Coflexip much simpler and
cheaper to use than rigid pipe for
many applications. In the Gulf of
Mexico, for example, a Coflexip
riser can be installed with a
smaller crew and vessel, in less
time, with greater tolerances, in a
shorter weather window, and with
a fraction of the equipment cost.
Workboats and small platform
cranes can take the place of huge
lay barges and derrick barges.
Plus, Coflexip lines are designed
to outlast rigid line.
This 10.000-psi WP., three-inch
Coflexip line has the same safety
factor and crush strength as rigid
API spec pipe, yet has a smaller
bending radius than rubber hose
with the same I.D. and pressure
rating (36" vs. 48").
Our literature on production
applications
gives
step-by-step
comparisons of Coflexip versus
rigid pipe installations.
