A piping spool is to be fabricated.
Construction code: ASME B 31.3
Service LPG liquid
MDMT : minus 45 degree Celsius
Client spec calls for impact requirements.
Pipe MOC is A 333 grade 6; Size 2 inch schedule 80 and 3 inch schedule 40.
My question is are these two thicknesses of 5.54mm and 5.49mm exempt from impact testing as per B 31.3 Fig. 323.2.2A curves ??
Please provide B 31.3 code reference.
