welded steel storage tanks postweld heat treatment of API 650 tank

The repad is part of the assembly that is stress-relieved.On a new tank,this would normally be a full-height section of the shell ring,not justJStephen,I understand about the application of API in the event of new construction. That seems very clear. If you read the section though,it sI'd weld the entire nozzle with repad into a shell insert plate,PWHT the whole assembly then install it in the tank.Also,look at using a thick shell insert plate to eliminate the repad welding testing. Just taper the insert-plate edges to meet the shell thickThanks everybody. It does seem like the whole assembly needs to be PWHT,shell,repad,and nozzles. They try not to use thickened inserts out herI read this with interest. I don't think everyone has replied completly to tankerator's question.Assuming his nozzle is not a flush type. So,iUnless the shell material is group IV or above,then it needs to be PWHT no matter what the size if the shell is greater than half inch.Since he referenced certain nozzles,I assumed the nozzle in question fell into that category.
