Comparison ANSI/ASME B31.3 AND B31.8
(OP)
We have new piping materials (including fittings)
all with correct material certificates , WPS and PQR and all according to ASME / ANSI B31.3.
Design pressure under 100 barg , design temperature between Zero and 80 Degr. Celsius
Is it possible to use the obove for a part under ASME/ANSI B31. 8 ( eight !!)
If THE answer is NO , how can we make this possible ? I mean which steps , recirtification , extra calculation, re-qualification, etc,.. have to be done to get a system approved for B1.3 also approved for B31.8

Don't get too concerned on temperature since your design is above the lower limits.
