METHOD FOR PRODUCING A TENSILE ARMOR CONFIGURATION OF A FLEXIBLE CONDUIT AND A CONNECTOR FOR A FLEXIBLE CONDUIT

摘要

The present invention discloses a method for obtaining a tensile armor configuration of a flexible conduit comprising the steps of mounting an end ring engaged with the terminal region of each wire of each tensile armor, defining an initial position, which axially displaces the end ring in opposite direction to a free end of the flexible conduit, from the initial position to an end position, so as to cause flexure in the wires of each tensile armor and securing the end ring in end position, to maintain the wires of each tensile armor flexed. The present invention also proposes a connector for a flexible conduit, said connector comprising an end ring engaged with the terminal region of each wire of each tensile armor and fixed in an end position so that the wires of each tensile armor are flexed.

1. A method for obtaining a tensile armor configuration of a flexible conduit, said flexible conduit comprising at least an internal tensile armor formed by a plurality of helically winding of wires and at least an external tensile armor formed by a plurality of helically winding wires, the external tensile armor is relatively superimposed to the internal tensile armor, said internal tensile armor is superimposed over a pressure armor, said pressure armor is superimposed in relation to an internal polymeric sealing layer, said flexible conduit having a free end, wherein the method comprises the steps of:
(a) cutting the external layers of the flexible pipe in relation to the external tensile armor in a first length towards the free end, so as to allow access to said external tensile armor, (b) cutting the wires of the external tensile armor and the wires of the internal tensile armor on a second length relative to the free end, wherein the second length is smaller than the first length, so as to allow access to the pressure armor and to define an extremity for each wire of the external tensile armor and an extremity for each wire of the internal tensile armor, (c) assembling an end ring engaged with the extremity of each wire of each tensile armor, defining an initial position, (d) axially displacing the end ring in the opposite direction of the free end, from the initial position until an end position, so as to cause flexure in the wires of each tensile armor, (e) fixing the end ring in the end position, to maintain the wires of each tensile armor flexed.
