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 (57) of successive windings of said wall strip form the wall structure. The interlocking sections (57) 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 (57) being formed such that in the extended position a carcass gap (53) is provided between adjacent interlocking sections (57) for accommodating relative movement there between upon flexure of the wall structure. An insert profile (50) is located in the carcass gap (53) of the tubular wall structure on an inside of the wall structure to at least partly cover the carcass gap (53).
