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.

No.Per API 650 Section 3.2.4,the tank is limited to one in.of water vacuum (roughly 25 mm). If the tank must be designed for 50 mm water vacuum,then this is a special design which is not covered by API 650Tanks ForemostForemost manufacturers 400 BBL Tanks,750 BBL Tanks,1000 BBL Tanks,1250 BBL Tanks,1500 BBL Tanks,2000 BBL Tanks,2500 BBL Tanks,4000 BBL Tanks and field erected tanks up to 450,000 BBL.All Foremost storage tanks are designed in-house by our team of engineers to industry standards using API 620,650 and 12F design codes.
