[MW:7084] ASME R STAMP

 

Dear All,

I'm going to make some Works inside of a dehydrator (please see attachment), the questions are:

1. If I cut the angle suports without Couch the shell, do i need an R stamp company for mantain the ASME stamp?
2. If I cut the angle suports and grinding the angle flush to shell, do i need an R company for mantain the ASME stamp?
3. For cutting the existents excentric reducers as and Weld others, do i need an R company for mantain the ASME stamp?

 

Please escuse my language, i'm not native speaker (or writer :D )

Thank in advance for your cooperation.

For ERNiCrMo-3 Fnumber is 43, please recheck WPS if they have specified some other filler such as NiFeCr-1, NiCrMo-9 falls under F45.

A Numbers are not applicable for non ferrous welds

No such condition as for P number/F Number should be same in Sec IX.

Dear All,

 

I want to prepare a WPS for ,

 

material ASTM B 423 (P No-45).

 

Process - GTAW

Construction Code - ASME B31.3

Welding Code - ASME BPV SEC IX

 

What is the F - No. of ERNiCrMo-3?  43 or 45?One of the  WPS in my hand says 45 !!!

I have reviewed ASME BPV SEC IX QW 432,F-No. section and found that 43.Now I need clarification from experts,which one is correct 43 or 45?

 

What is the A - No. of ERNiCrMo-3? I have reviewed QW 422 A-Numbers section,but couldn't find.

 

Is there any condition that P- no. and F- no. shall be same?

 

Seniors, I need your help on this issue.
