Abstract:
An elongate metallic or polymeric or composite tape is disclosed along with a method of manufacturing such tape. The tape is of a type suitable for forming at least one helically wound layer of interlocked windings in a flexible pipe body for transporting production fluids. The tape is configured for interlocking of adjacent windings in the layer of tape by nesting a hooked region of a winding in a valley region of an adjacent winding. The tape comprises first and second elongate tape elements arranged in contacting relation.
