Debate: Do we still need to hot-pass everything or is that old school thinking?

I was up at a refinery in Gary last month on a 2-inch schedule 80 line. Foreman wanted full hot-pass on every root. I pushed back saying for that wall thickness it's just wasting rod and time. He didn't budge. What's the rule of thumb you guys go by on when to skip the hot-pass?

...and that's exactly the kind of thing I see everywhere now, not just in welding. Like people doing full oil changes every 3,000 miles on a modern car that's designed for 7,500. They're scared to trust the engineers or their own experience. Your foreman probably got burned once on a thin wall root that cracked, so now he's making everyone hot-pass everything forever. It's the same thinking that makes restaurants replace perfectly good fryer oil every night, just because that's how they were taught. The real trick is knowing when the extra step actually matters, like on heavy wall pipe with high pressure, not on that 2-inch schedule 80 you were on.

Wait, are you saying I've been wrong about the oil change thing this whole time?
