Notes 1. Where these criteria cannot be met due to physical limitations with layout dimensions, each longitudinal weld affected shall be subject to 100% RT and 100% MT or PT on the inside and outside surfaces for a distance of 10 in (250mm) from the affected end. 2. Where these criteria cannot be met due to physical limitations with the layout dimensions, the affected welds and the base material ligament in-between shall be subject to 100% MT or PT on the inside and outside surfaces. For branches with reinforcing pad, the pad shall cross the longitudinal or circumferential weld by 2in (50mm) or 2t (whichever is greater) and the weld covered by the pad plus an additional 2in (50mm) shall be ground flush and subject to 100% RT and 100% MT or PT prior to fitting and welding the reinforcing pad. 3. Where these criteria cannot be met due to physical limitations with the layout dimensions, the attachment weld (or reinforcing pad if used) shall cross the longitudinal or circumferential weld by 2in (50mm) or 2t (whichever is greater). The weld covered by the attachment weld (or reinforcing pad) plus an additional 2in (50mm) shall be ground flush and subject to 100% RT and 100% MT or PT prior to making the attachment weld.
