[MW:26009] Impact testing requirements for ASME B 31.3


Dear Experts,


Please clarify my below queries regarding the impact test requirements for Piping.


1) 3 inch SA105N WNRF  impact tested at zero degrees( at mill) Celsius but MDMDT is 18o Celsius can we use this flange with respect to ASME B 31.3( if yes please detail the reference standard and up to what temperature we can use this flange)


2) SA 234 GR WPB (90 degree elbow) MDMT is -450 Celsius but impact tested at Mill is -290 Celsius, can we use this flange with respect to ASME B 31.3.



Thanks and Best Regards?
