I am using ISO 14692 for GRP stress analysis, the "Recommended Load Cases " by CII includes EXP load case which as far as I know is not addressed by the code. Does CII recommend the same load case(probabley as per ASME B31.3) for all other codes ?

The Recommended load cases from CII work well for most steel piping systems without multiple temperatures, settlements and so on. So actually these cases are of little help.
Especially for GRP piping these load cases are plain wrong. You should check the code you're using (UKOOA, BS7159 or ISO14692) for the load cases and allowable stresses you should use.

ISO 14692 for GRP specfies only three loading types:
1. Occasional
2. Sustained including thermal loads
3. Sustained excluding thermal loads
which correspond to OCC, OPE and SUS load cases in CAESAE II respectively.

CAESAR II includes EXP load case for ISO 14692 for reference only. As a matter of fact, CAESAR II only calculates the code stresses, and sets allowables to zeros for EXP load case.

As for the last question, you are right. CAESAR II recommend the "B31.3 load case set" for all jobs.

Hi

Please see below link in GRP / FRP Piping analysis. It is eloborative. GRE/GRP/FRP analysis is done according to UKOOA/BS7159/ISO14692. The latest ISO 14692 code gives more specific by covering Shell dep. findings. Till CEASAR 5.1, there is no ISO 14692 incorporated in CII. However, by using UKOOA, and making some modifications to it, possible to simulate ISO 14692 requirements. From below link, you may see Richard Ay suggestion to simulate ISO 14692.
