Requirements for welding to outside of vessel

[bradsr0138]

I have a small break vessel that has a bracket on the outside that needs to be moved inorder to facilitate installation. The vessel has already been hydro tested, and does not require PWHT.

My question is: Are there any specific requirements as per code that i need to be aware of in order to but off this bracket and re-attach it in a different location. The vessel material is 304H SS.

Thank you for any help provided, it is greatly appreciated.

An external attachment weld can be done post hydro, there should be no issues. If concerned, ask your local AI which is alawys a good idea.
