FRP pipe allowable stress

[saliba11]

Hello all,

I am analysing a 30" fire water FRP pipe according to Asme B31.3 using Caesar II.

31.3 appendix A does not contain allowable stress value for FRP pipe. I need to have it to compare with the code stress.


Does anyone know how can I find the allowable stress values for FRP pipe.

thanks in advance

In terms of design and stress analysis, it may be beneficial to review ISO 14692

Be very careful of using ASME B31.3 for FRP analysis.

The vendor should always be consulted on the properties of their products for FRP. A stress analysis package that can combind the different types of manufacturing methods of the pipe/fitting needs to be used, Caesar II/Triflex etc, consult the manual for the set-up of CII for FRP anaylsis. Use BS 7159/UKOOA or similar code to evaluate the stresses.

A manufacturer that I used to use in SA is FiberWound for this information. Please also consult with COADE when setting up the program CII, especially the SIF & Pressure stiffening.

Sorry if this response is a bit late.
