Key Design Decisions IPS vs. DIPS

DIOD – Ductile Iron Outer Diameter

DIPS – Ductile Iron Pipe Size IPS – Iron Pipe Size

Pressure Requirements DR9 for water pipe 4-inch to 32-

inch SDR 9 (CTS) for small diameter

tubing DR17 for sewer pipe

Thrust Restraint at Connections to other Materials

Embedment Material

How Did C906 Change? AWWA C906 Polyethylene (PE) Pressure

Pipe and Fittings, 4 In. Through 65 In. for Waterworks

Major Update in 2015 1990, 1999, 2007

Includes PE 4710 resin Change in pressure design
