COFLEXIP & Services Inc. In drilling, it outperforms both hose and pipe with swivel joints Coflexip  flexible  pipe  lowers  costs and   raises   the   safety   factor   on drilling rigs. Coflexip    initially    costs    more than  other  Alternatives  for  choke and kill lines, cementing/acidizing/fracking    lines and other drilling jobs.  But it lasts so   much   longer   that   the   cost   is actually    lower    in    the    long    run. That's based on the materials cost alone.          If     the     downtime     cost avoided by a line that lasts longer is    included,    Coflexip    is    cheap compared to other solutions. For  many  jobs,  Coflexip  is  a lot  safer  than  rubber  or  pipe  with swivels   because   of   its   strength, durability, and corrosion resistance.  What price can be put on that? Our literature on drilling applications  tells  exactly  how  and where     Coflexip     can     save     you money. Actually tougher than rigid steel pipe In   comparison   to   API   5LX   steel pipe,   Coflexip   flexible   steel   pipe generally has better abrasion resistance, better corrosion resistance, and better resistance to vibration and flexing fatigue. It    requires    less    maintenance    in most applications and it is compatible   with   more   chemicals, including H2S. Compared to reinforced rubber hose,   Coflexip   has   greater   crush strength, abrasion resistance, ultraviolet  resistance,  and  flexing- fatigue resistance.  It stands up to a wider range of chemicals, including  H2S,  and  suffers  almost no aging damage. Coflexip works because of a unique design Coflexip  is  a  unique  combination of high-strength steels and thermoplastic. In  the  basic  Coflexip  construction, the     carcass     of     interlocking     Z- section   steel   handles   the   radial loads,  including  internal  pressure, and keeps the pipe Crush  strength  of  Coflexip  pipe  is demonstrated by parking a truckload of drill pipe on a piece of rotary   hose.      The   pipe   remains perfectly round under the 9.000-lb. direct load. from kinking or collapsing. Alternating  spiral  layers  of  heavy steel wire handle the tension loads and give the pipe a tensile strength comparable to rigid pipe. Outside and inside, thermoplastic    layers    protect    the steel components against corrosion     and     make     the     pipe leakproof.      There   is   no   bonding between   layers.      When   the   pipe bends, each layer The   interlocking   spiral   of   steel   - section   is   the   structural   element that   withstands   radial   loads   from internal    and    external    pressures. and keeps the pipe from kinking. moves  independently.    That's  why the  fatigue  resistance  of  Coflexip is     much     higher     than     that     of reinforced hoses. For  most  drilling  applications. the    outer    thermoplastic    layer    is covered with a stainless steel wrap for extra protection. For production   applications,   an   extra stainless  steel  layer  goes  on  the inside,   to   prevent   damage   from TFL tools. That's the basic structure. Dozens of Coflexip structures have  been  developed  for  specific applications  in  sizes  from  I  to  22 inches I.D., with working pressures up  to  15,000  psi,  and  continuous lengths of more than one mile. There     is     no     bonding     between layers  in  the  Coflexip  structure  as there is in the structure of reinforced rubber hose. That's    why    Coflexip    has    such extreme'   high   resistance   to   flex fatigue.      Four   inch   Coflexip   pipe has    withstood    1,600,000    flexing cycles under a 10.0(0 psi maximum working pressure before failure     due     to     the     unnaturally induce temperature of +1001°C. A long list of uses Since    1972,    Coflexip    has    been successfully  used  in  almost  every major  oilfield  in  the  world.    In  the Gulf   of   Mexico   and   onshore,   it serves as: •· Offshore platform risers •   Subsea flowlines •   Jumper lines •   Subsea mudslide protectors •   Vent and flare lines •   Temporary production systems •   Permanent production systems
