Piping
The engineering and inspection of FRP piping is very different from steel piping. A special training in the engineering of FRP piping is absolutely necessary to make a good design. The design combined with the quality of manufacturing and installation is essential for the lifetime of the FRP piping system.
Visual inspection is almost the only way to inspect FRP piping. You can find a list here with the main items for the (visual) inspection of FRP piping here.
