COMPONENT DIAGRAM
PIPE SECTION — SCHEDULE = WALL THICKNESS WALL: — OD: — LENGTH: — — — PN: A5749 · OEM ⚠ 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 PARTSTABLE TECHNICAL DRAWING — NOT TO SCALE
