[MW:20853] Flange material SA-266 Gr.4

Dear All,

 

We are having U-Stamp vessel with a body flange and nozzle weld neck flange material SA-266 Gr. 4 designed according to appendix 2 of ASME Sec VIII Div.1.

Our clarification:

 

Is it required to consider supplementary requirements as per paragraph 3.4 of SA-266 or not?

 

Best Regards.
