<p>A method of forming a tubular conduit comprises providing first and second ring moulds (14, 16). A plurality of generally flat wall members (12) provide inner (22) and outer (20) liners for the tubular conduit. The method comprises deforming the wall members (12) to provide tubular members (20, 22), arranging the tubular members (20, 22) to extend between the first and second ring moulds (14, 16) to define an annular space therebetween and disposing a curable material (18) in the annular space to provide a core layer between the inner and outer liners (20, 22). A tubular conduit formed by such a method is also claimed.</p> |
