  • "ROV" 
  • The inside surface of an I/J-Tube is often difficult to coat with traditional anti-corrosion systems, such as paint or application of anodes, etc. Hence a sealing device is often installed into the bottom of the tube, in order to seal the annulus between the I/J-Tube and the umbilical/flexible pipe and then the annulus is filled with corrosion-inhibited water. EXSTO typically manufactures two different types of I/J-Tube seals:

    Diver-installed Seal

    Diverless/Pull-in Seal

    In addition to the above standalone systems, EXSTO also manufactures combinations of Seals, Centralisers and Bend Limiting devices where a more comprehensive protection system is deemed necessary.
