C O F L E X I P & services inc - An intermediate polyethylene sheath separates the steel carcass from the crosswound armors and provides an extra leak proof layer. - Double crosswound armors resist axial and torsional loads. - The polyethylene outer sheath protects the pipe from external corrosion and ensures binding of the underlying armors. - The Rilsan outer jacket provides an extra protection during the bottom tow of the flexible pipe on the seafloor. See Figures II-1 and II-2. Coflexip   pipe   is   manufactured   in   long   continuous   lengths   which   are   spooled   on   storage/installation   reels.      The connections are mounted at both ends of each section, and the entire lengths are subsequently pressure tested in the factory.  The end connections have reached such a high degree of reliability that they retain all the characteristics of the pipe  with  a  substantial  safety  factor.    The  end  connections  also  undergo  a  Ni-Kanigen  corrosion  protection  treatment. This treatment consists in anchoring, by a non-electrolytic process, a penetrating layer of nickel into the steel. The  total  length  of  the  Drinking  Water  Discharge  line  is  2,500  feet,  made  in  one  continuous  section.    Each  end  is equipped with an ANSI B 16.5 series 150, raised face flange. See Figures 11-3 and 11-4.
