Re: [MW:23726] Impact Test Requirement for Welds of API-650 Storage Tank when Design Metal Temperature is below -7°C

Hi

Also check your Client requirement / data Sheet of fuel oil tank for design metal temperature and you may consider the impact test requirement.

Hi

Please consider API 650 only for qualifying WPS/PQR.

Dear All,

A Fuel Oil tank has been designed as per API-650 code and it is mentioned in this code that when design metal temperature is below -7°C impact test shall be carried out for all welds for all components. The statement in code is given as: 

"9.2.2.2 When the design metal temperature is below -7°C (20 OF), impact tests of the weld metal shall be made for all procedures used for welding the components listed in 4 2.10 1, for welding attachments to these components, and for fabricating shell nozzles and manholes from pipe and forgings listed in 4.5. 

In our case, design metal temperature is below -7°C i.e. -10°C but still welding engineer is insisting that impact testing is not required as per ASME Section IX (QW-403.5).

My question is that Tank is designed as per API-650 and there is no reference that ASME section IX would supersede  the above statement of API-650 where impact testing shall be carried out when Design Metal Temperature is below -7°C.

Can anybody guide on this subject.

Thanks in advance
