Glass reinforced thermosetting plastic pipes share with thermoplastic pipes the advantages of corrosion resistance and lightness. They are currently finding increasing market acceptance, especially for large diameter water distribution and sewerage applications where the alternatives of concrete, steel and asbestos cement often prove more expensive when a corrosion resis- tant liner has to be added. Much effort is being applied to the optimisa- tion of GRP pipe design, Accepted methods of analysis of flexible pipe behaviour are generally used, but the composite nature of GRP, although complicating design procedure, is advantageous because it enables the material properties to be tailored to meet the particular structural require ments .

The influence of the incorporation of injection moulded fittings and the presence of mirror plate butt welded joints on the performance of polyethylene pipe systems has been assessed. Systems have been tested at 79.5OC under, predominantly, internal fatigue pressure loading. Both fittings and butt welded joints have...
