Patent ID: 8302633

Claim:
A flexible pipe comprising: a flexible cylindrical tubular pipe body having a first end and a second end respectively connected to first and second rigid connector end fittings in the form of a sleeve, the wall of the pipe body being mechanically reinforced by at least one layer of filaments of small thickness presenting high traction strength, the filaments being wound helically about the longitudinal axis of the pipe; wherein the at least one layer of filaments includes an array of uninterrupted filaments interconnecting the first and second end fittings alternately in one direction and then in the other direction, while being fastened on the first and second end fittings; wherein the filaments are fastened on the first and second end fittings by mechanical lashing members provided at their peripheries, wherein the mechanical lashing members include one of a shoulder or a set of pins around which the filaments pass and are engaged; a cylindrical envelope in which the at least one layer of filaments lie, wherein the lashing of the at least one layer of the filaments is made so as to prevent the filaments from moving away from the cylindrical envelope, making the at least one layer of filaments a traction layer; and wherein the at least one layer of filaments have a winding angle relative to the first and second end fittings that is greater than 54.7°, such that an internal pressure within the flexible pipe will cause the traction layer to clamp more tightly onto the first and second end fittings.
