As such there is no restriction in lieu of 360 ° banding, probably you may follow para 8.2.2.2 of API 570, but why do you go for this for a 10" dia pipe?

Dear Sirs
Pls advise if it is acceptable to ASME B31.3 Code.
Base Material Group - P1 x 10" dia x Sch 160.
Weld Process- GTAW and FCAW.
Carried out RT after PWHT.
Found 30mm defect at 9 o'clock position . Repaired.
Can i perform localized reheat treatment overlapping defect repaired location at least 100mm on both ends?
Thanks
