These pipes can be manufactured with bends, reducers, and cast-in mild steel, cast iron or plastic fittings.
Reinforced concrete pressure pipes are designed for the combined effects of external load and internal (in service) pressure. Australian/New Zealand Standard AS/NZS4058: 2007 Precast Concrete Pipes (Pressure and Non-Pressure) gives a minimum requirement for factory test pressure of 120% of working pressure in the pipeline.
Rubber ring jointed (RRJ) pipes are recommended for all concrete pressure pipe applications. RRJ pipes up to 1,800mm dia are supplied with a belled socket joint while those larger than 1,800mm dia are supplied with an in-wall joint.
