⚠ VERIFY BEFORE ORDERING
Schedule = wall thickness, NOT pipe diameter. Sch 40 and Sch 80 have the same OD but different wall thickness.
Nominal pipe size ≠ actual OD — a 1" pipe is actually 1.315" OD
✓ BROKER TIP
Sch 40 = standard wall, Sch 80 = heavy wall (higher pressure), Sch 160 = extra heavy.
Seamless pipe is required for high-pressure applications — welded pipe has lower ratings
