Re-pad for self integrally nozzle
Re-pad for self integrally nozzle
(OP)
Hi,
Can I use reinforcement pad for self integrally nozzle? The area available is less than the area required, so I want to use Re-pad to increase area available.
Thanks for your quick response

1) Code of Construction
2) Materials, temperatures, pressures
3) A better explanation of what you mean by "self integrally nozzle".

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Ok, to follow on with TGS4's thread... You are an engineer. Be specific. Fine, you have an ASME Section VIII vessel. Shall we ask three more questions in this game of 20 Questions? Is your enquiry related to:
ASME VIII Division 1?
ASME VIII Division 2?
ASME VIII Division 3?
Are there service considerations such as cyclic service or thermal shock which might impact the decision making if an experienced engineer were involved?
But to jump to some opinions here based on a statistically likely response that the vessel involved is a Div. 1 vessel with no service considerations:
Can you use a repad to increase the area available for a typical integrally reinforced nozzle configuration? Yes, the code does not prohibit this.
But... Consider the impact to your reputation prior to going down this road. If I have to venture a guess, you are working for a fabricator who (ahem) "poorly machined" a forging and is now trying to find a way to make it work despite good engineering judgment. I really hope you are not involved in the design of any vessels which my company will wind up owning.
There are high quality consultants in your province. I suggest you consult with one.

Is it possible?

I'll also say that, as your customer, if I were asked to approve this detail, I'd not likely do so. If "surprised" with it, I'd likely not accept the vessel.
You need to do your homework before proceeding.

Might run it by your AI as well, make sure you can get it stamped, if required.

EDIT: Can you get there by making the fillet weld bigger?

Alternatively, use Code Case 2695 for a nozzle in a head. Code Case 2695 will need to be mentioned in the Manufacturing Data report. It is not compulsory, however informing the customer may be a good idea.

One more solution, increase the local shell thickness with inserting the insert plate, will help you to increase the available area of reinforcement.
Try this one.
Thanks
