ABSTRACT:
A method and apparatus for manufacture of structures having flanged nozzles attached thereto and, more particularly, a method and apparatus for attaching flanged nozzles to pipe headers in manufacture of reinforced thermosetting resin structures. A main pipe section is provided with a through branch outlet, and a shaped mold is provided to fit through the outlet and to fit in a tight fitting relationship with a preformed flanged nozzle. Parts of the main pipe section and the preformed nozzle which are adjacent to the mold are chamfered on the outside. Resinous matrix laminates are then provided to cover the mold and adjacent parts of the main pipe section and the preformed nozzle. The method provides a smooth corrosion resistant interior joint between the pipe header and flanged nozzle, with a new primary laminate providing both corrosion resistance and strength properties comparable to preformed pipe parts of the same resinous matrix laminate materials.
