  • Connecting endpiece of a flexible pipe with a spacing member, associated flexible pipe and method
    Patent number: 10113677
    Abstract: This endpiece includes at least one end segment of each armor element, an end vault and a cover, the end vault and the cover delimiting between them a chamber for receiving the end segment and a material for filling the receiving chamber, in which the end segment is embedded. The endpiece includes a spacing member positioned so as to internally bear upon the end segments of the armor elements of at least one armor layer. This spacing member defining, on at least one end segment of a armor element of said armor layer, contact areas axially spaced apart along said end segment, the contact areas delimiting between intermediate contact spaces between the filling material and the end segment.

  • High-resistance end fitting for a flexible tubular pipe
    Patent number: 8096589
    Abstract: An attachment fitting and a method for connection to a tubular duct comprising at least one ply of armors, the armors having a free end respectively defining an outer surface, the attachment fitting comprising a bushing and a sleeve having an attachment part and a connection part with a reception portion, the sleeve being mounted on the duct by spreading the free ends of the armor perpendicularly to the reception portion, the armors comprising a widening device, the bushing being mounted about the connection part and forming an annular chamber for receiving a flow of a mass-curing material for encapsulating the free ends of the armors. The widening device connected to the free outer surface of the free ends of the armors.
