Connection endpiece for flexible unbounded tubular pipe to transport petroleum products in marine environment, has sealing and setting units for sealing and setting pressure sheath after assembling endpiece on pipe

摘要

The endpiece (10) has an internal pressure sheath (3), and traction weaving webs (5, 6) that are rolled up around the sheath. Each web include a front edge (22) arranged on an isolated part (20) spaced from a separation point of the sheath. A cylindrical cap (15) extends from an end arch (11) and forms a seal (16) on an external sheath (7). Sealing and setting units seal and set the pressure sheath placed between front edges of the isolated parts and the end arch after assembling the endpiece on a flexible unbounded tubular pipe (1).
