II. COFLEXIP PIPE AND COUPLING
Coflexip pipe is primarily made of steel and thermoplastic, and its structure is based on the modular assembly of
independent layers; the steel components insure the mechanical properties of the pipe, while the plastic sheaths render it
leak and corrosion proof.
For the ROWPU barge Drinking Water Discharge System, a heavy duty structure has to be used, since the flexible line
will have to be handled in a general environment which cannot be anticipated or controlled. Also deployment of the line
will be carried out very rapidly during less than favorable weather conditions. Therefore, it is necessary that a reinforced
structure be used so that the integrity of the line be ensured.
The structure of the Drinking Water Discharge System includes six (6) layers:
The inner polyethylene tube renders the pipe leak proof and protects it from corrosion and abrasion.
The galvanized, interlocked steel carcass provides resistance to internal and external pressures. It also resists
mechanical crushing and kinking.
