Repad requirements for system header stub-ins

[Hummie]

Was wondering where I could find or what are the requirements for installing repads at nozzel stub-in locations on a system header if any. Presently I am looking at a project that has a 20" header with 16" stub-ins both standard wall thickness. I am thinking that it would be in Section VIII Div 2 but not 100% sure.

Any info will be greatly appreciated.

Thanks,
TD

Did you look at SecVIII Div. ,Appendix 1,Item 7?

You may be able to view this as "pipe".

If this is pipe that falls under ASME B31.3, Reinforcement requirements are covered in para. 304.3.3 and Fig. 304.3.3. There are also some sample calculations in Appendix H.
