Dear All,

Vessel Data,

MDMT = ( - 30 Deg C),

Plate thickness = 12mm,

Dished end = 12/14,

Material = SA 516 Gr.70 N.+ HIC

Design Code - ASME Sec VIII DIV 1.

Is Impact testing required ?

As per UG-20 (f) (3) ,

"Design temperature is no warmer than 650°F (345°C) nor colder than −20°F (−29°C). Occasional operating temperatures colder than −20°F (−29°C) are acceptable when due to lower seasonal atmospheric temperature."

Is there any provision for wave Impact testing as per code provision(s). Kindly advise.
