Fiberglass (FRP) Pipe is produced using the continuous advancing mandrel (filament wound) process, which represents the state of the art in FRP pipe production. Using technology developed by material specialists, a very compressed laminate is created that maximizes the contribution from the three basic raw materials glass-fiber, resin and sand.
