Abstract

1279410 Composite pipe REDLAND PIPES Ltd 16 Oct 1969 [17 Oct 1968] 49226/68 Heading F2P A composite pipe comprises an inner core pipe (preferably of metal, ceramic, plastics, asbestos cement, or concrete based on normal cement or synthetic resin) wound with resin-impregnated filamentary reinforcing material (e.g. of glass, carbon, nylon or wire), the filaments being under equal predetermined high tension (e.g. in excess of 20,000 lbs./sq. inch and a comparable proportion of the U.T.S. for other filaments). The winding may be helical or circumferential and evenly spaced uniformly tensioned longitudinal filaments may be retained by later hoop windings.
