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.
