Coflex Hose

FEATURES
1.  Applicable  as  connection  part  when  drill  platform,  semi-submersible  drilling  vessel  or  drilling  vessel  moves  relatively  and  for  adjustment  of  the  installation  variance  of  the  drilling  rig.  It  can  be  used  for  delivery  of  oil,  gas,  mud  and  other  high  pressure  media  (including  mainly  relief  line,  BOP  line  and  choke  &  kill  line  hose).
2.  Conforms  with  API  Spec  16C.
3.  High  pressure  resistance,  thermal  insulation,  anti-flaming,  fire  resistance  and  high  abrasion  resistance  inner  wall.
Structure  Function:
Inner  core:  preventing  bleeding  out  and  resisting  erosion.  Adhesive  texture  layer:  bonding  the  wireline  together  and  eahancing  the  mechanical  strength  and  ability  of  bearing  high  pressure.
Double  cross  wireline  layer:  resisting  of  axial  load,  distorsion  stress  druing  movement  and  operation,  high  internal  and  external  pressure.
Heat-insulation  layer:  prohibiting  heat  transmission  and  slowing  down  the  temperature  change.
Fire-resistance  layer:  preventing  the  hose  from  damage  under  the  condition  of  high  temperature  and  open-flame.
Buffering  and  sealing  layer:  prothcting  the  hose  from  inrushing  and  erosion  of  external  fluids  and  buffering  the  shock  of  external  force.
Stainless  steel  jacket:  resisting  abresion  and  prolonging  the  life  of  hose.
Exeutive  standard:  API  spec.  16C  NACE  MR  0175-2003
