@ Mr Richard, please there was an argument between me and one of our client consultant regarding using two different piping codes (ISO 14692 and B31.3) in one system that has two different material properties (FRP Pipe and Carbon steel Pipe).
At the meeting, the consultant asked why using B31.3 for the model and i replied by telling him that the system is a hybrid system since it has both carbon steel and FRP properties therefore its advisable to use B31.3 since it can handle both materials together, But the consultant disagreed with me and said its possible to run the stress analysis with two different piping codes for the system that have two different materials.
please can you confirm if the consultant is right and also how do can combine such and produce a reasonable stress analysis result.
finally, if anyone has done such combinations, please kindly lecture me in details.

Many Thanks in anticipation.
Piper charles
