Abstract
A reinforced pipe section comprises a metal pipe, a layer of dry fibers disposed around the metal pipe, and an external liner covering the layer of dry fibers. A method of manufacturing a reinforced pipe section comprises wrapping a layer of dry fibers over a metal pipe, and covering the layer of dry fibers with an external liner, thereby forming a first dry fiber wrapped metal pipe. A method of reinforcing a degraded metal pipe comprises wrapping the degraded metal pipe with a layer of dry fibers to increase the hoop strength of the degraded metal pipe, and covering the layer of dry fibers with an external liner.
Claims23
A method of manufacturing a reinforced pipe sections comprising:
- wrapping a layer of dry fibers by hoop winding a plurality of dry fibers around first and second metal pipes in a manufacturing facility;
- covering the layer of dry fibers on each metal pipe with an external liner without the application of a resin and without subsequent curing during fabrication thereby forming dry fiber reinforced metal pipes in a manufacturing facility;
- positioning the second dry fiber reinforced metal pipe adjacent to the first dry fiber reinforced metal pipe at a field location;
- connecting the second dry fiber reinforced metal pipe to the first dry fiber reinforced metal pipe via a weld at a field location;
- wrapping the weld by hoop winding a layer of dry fibers onto the weld area at a field location;
- and
- creating an external liner over the layer of dry fibers disposed around the weld without the application of a resin and without subsequent curing during fabrication, thereby forming a dry fiber reinforced weld area in a field location.
