  • Patent number: 6412825
    Abstract: An assembly of an end-fitting and a flexible pressure pipe which is of a non-bonded structure and comprises a number of layers including at least one layer (5) having a number of helically wound flat metallic tensile armour wires with end parts which, in the assembled condition, are embedded in an anchor consisting of a casting material such as epoxy which is injected into a cavity formed in the end-fitting. The flat wire end parts have at least one twist turning generally around the centerline of the wire. Said twists lock the tensile armor wires firmly in the anchor and therefore provide a greater resistance to axial tensile loads acting on the assembly than has been known before. Furthermore the joint is a simple and cheap structure and can be made in situ.
