Mihir,

max reinforcement is given in table PW-33, and depends on the thickness of the parent metal, and the type of weld (circf. in pipe and tube or other).

I don't know about sect IV.

Sec IV is more forgiving in the construction of
low pressure, I would use the same criteria construction as Sec I for the higher pressures,
since there are no rules it is safer that way,
note that some Companies even xray the long-seams in Sec IV
as well because they want to be asured of the quality,
I may do the same in the future.
