FLEXIBLE TUBULAR LINE WHICH IS SUITABLE, FOR EXAMPLE, FOR OIL EXPLOITATION, COMPRISING A PTFE COIL

摘要

The invention relates to a flexible tubular line (10) which is intended, for example, for the transport of hydrocarbons. The inventive line comprises successive independent layers consisting of (i) helical coils (1, 4a, 4b) of strips or different sections and (ii) at least one polymer sheath (2, 5). According to the invention, at least one coil (11) is produced from strips (12) of polytetrafluorethylene (PTFE).
