Rigid wound or reelable pipe ( 1 ) for transporting hydrocarbons having a single-walled or double-walled envelope comprising two coaxial pipes, internal ( 2 ) and external ( 3 ), respectively, separated by an annular space, comprising at least one electrical heating cable ( 10 ) capable of being subjected to an elongation of 0.5% without sustaining damage and produced, for example, in the form of a central conducting braided cable surrounded by an electrically insulating sheath. The materials comprising the cable are subjected to elastically deformation by remaining below 15% of their elastic limit and preferably below 5%.
