I beleive FRP/GRE/GRP Vessel Vendor provides nozzle allowable forces and moments.

Is there any code or standard to calculate Nozzle allowable forces and moments on FRP/GRE/GRP vessels with respect to size and pound rating?

Does one need to perform any code checks as per BS 7159?

Could somebody define the code checks required while performing FRP/GRE/GRP pipe stress analysis.

Can CAESAR-II perform buried FRP/GRE/GRP pipe stress analysis?
