Hi Engineers How to weld clean ou

Hi Engineers
How to weld clean out door base plate with annular plate? What is the welding procedure?

RE: Hi Engineers How to weld clean ou

This is an API Storage Tank question ... Suggest that you post in "Storage tank engineering" forum

RE: Hi Engineers How to weld clean ou

I don't remember if there is any additional detail on that in API-650. But it may simplify things, at the cost of some material, to extend the base plate in as far as the annular plate.

RE: Hi Engineers How to weld clean ou

I attached the photos of COD our API 650 Storage tank.
Tank Details:
Dia : 200 ft
Height : 48 ft
COD Base plate Thickness : 34mm
Annular plate Thickness ; 14 mm
As in our case, we are going to only replace the bottom reinforcement plate (or annular plate) of the clean out door.

Does we have to stress-relief the whole clean-out door assembly afterwards? or just PWHT of the new welding of the new annular plates to the new door reinforcement plate?

Or, in this case, is not required.

Please advise me.
