<p>A reinforced pipe section (100) comprises a metal pipe (110), a layer of dry- fibers (120) disposed around the metal pipe (110), and an external liner (130) covering the layer of dry fibers (120). A method of manufacturing a reinforced pipe section (100) comprises wrapping a layer of dry fibers (120) over a metal pipe (110), and covering the layer of dry fibers (120) with an external liner (130), thereby forming a first dry fiber (120) wrapped metal pipe (110). A method of reinforcing a degraded metal pipe (110) comprises wrapping the degraded metal pipe (110) with a layer of dry fibers (120) to increase the hoop strength of the degraded metal pipe (110), and covering the layer of dry fibers (120) with an external liner (130).</p> |
