Do you agree for rigid flange test pressure as per B16.5 recommendations, pipe 20"-STD-D.P=225psig Temp=575F hydrotest pressure=1125 psig.

Do you agree with hydrotest pressure..Its does not make sense to me right.

300# flange test pressure 1125 psig its OK as per B16.5 recommendation, but this does not apply to pipe right for hydro test pressure to consider in pipe.
