Dear cristina,

Be shure to analyse first of all the OPE case including the axial expansion due to temperature and pressure. Codes compliance can be performed using Caesar II based on BS7159 or UKOOA codes.

The Caesar II manual provides some basic information on FRP stress analysis, but be shure to get the material prop. and allowables from the piping material vendor. Some technical data can also be found on the vendor hompages, e.g. www.futurepipe.com.
