摘要
The invention relates to a flexible pipe carcass comprising a flexible tubular wall structure comprising a helically wound wall strip; wherein interlocking sections of successive windings of said wall strip form the wall structure. The interlocking sections of adjacent wall strips define a length and are movable with respect to each other between a first position and a second, extended position for changing said length, the interlocking sections being formed such that in the extended position a carcass gap is provided between adjacent interlocking sections for accommodating relative movement there between upon flexure of the wall structure. An insert profile is located in the carcass gap of the tubular wall structure on an inside of the wall structure to at least partly cover the carcass gap.
