PIPE EXPLORER
See how our pipes change with size and class
Pick a pipe, a size and a class. The cross-section is drawn to true proportions, and the wall, bore, weight and pressure update as you go.

HOW TO READ IT
Three things that change, and one that doesn't
The outside stays the same
Every class of a size has the same outside diameter, so pipes and fittings always match. A higher class adds wall on the inside, so the bore gets a little smaller.
Class is pressure
The class is the working pressure in bar at 20 °C: Class 9 is 9 bar, 900 kPa, about 92 m of water head. Sewer pipe is non-pressure: its class (34 or 51) describes the wall instead.
SDR ties it together
SDR is the outside diameter divided by the wall. Pipe of the same material and SDR has the same pressure rating at every size. See the pressure class guide.
Walls are the minimum for each size and class. PVC mass is per pipe (6 m effective length; 5.8 m from 355 mm); HDPE mass is typical per metre. Bore and water volume are worked out from the minimum wall, so treat them as approximate. For tenders, use the certified figures on each product page and our certificates.
