Schedule 40 pipe and PVC fittings, 1/2 to 2 inch
What is the actual outside diameter of 1/2, 3/4 and 1 inch Schedule 40 pipe? · Hardware · basis: ASME B36.10 / ASTM D1785; nominal pipe size (NPS)
- sizes
- 6 in table
Notes
- Nominal size is not the OD. Fittings grip the OD listed below; a printed adapter that slips over the pipe uses OD + 0.3 mm; one that goes inside a fitting socket uses the same OD − 0.2 mm.
- Wall thickness is Schedule 40 PVC; steel Sch 40 shares the OD.
