Dear Experts,

 

Please help me to clarify issue as below:

 

Solid rod ER70S-G have been used for weld joints of HP Flare KO Drum by using WPS V02 (GTAW/SMAW – Impact test is not applied). Certificate of welding consumable ER70S-G indicates that impact test temperature is –30°C. Minimum design metal temperature (MDMT) of HP Flare KO Drum is –45°C. Material of HP Flare KO Drum is SA-516 Gr60 normalized.

In accordance with para.UCS-67(a)(3) ASME BPVC.VIII.1-2017 , is it a requirement to perform impact test at –45°C for welding consumable ER70S-G?

 

Thanks

 

Gigi.
