The present disclosure relates to a flexible pipe including a pipe body that extends along a central longitudinal axis. The pipe body is made from a strip that is helically wrapped in a plurality of convolutions. The strip includes inner and outer hook portions that interlock to form an interlock seam between adjacent convolutions. The pipe body includes a mid-portion positioned between first and second end portions. At least the first end portion has an axial length L1 that traverses at least several of the convolutions of the pipe body. The first end portion is crushed radially inward relative to the mid-portion such that the first end portion has an effective outer diameter D1 that is smaller than an effective outer diameter D2 of the mid-portion. A first transition region is positioned between the first end portion and the mid-portion. The first transition region provides a diameter transition between the outer diameter D1 of the first end portion and the outer diameter D2 of the mid-portion. The first transition region has an axial length L2 that traverses at least one of the convolutions of the pipe. |
