HDPE pipe is very durable and flexible and can be bent on site to a radius twenty-five times the nominal pipe
diameter – for SDR11 and SDR17 pipe, at or below 20°C ambient temperature. This provides major cost savings,
when compared to different pipe systems, some of which require glued fittings, restraints or thrust blocks for
even minor changes in direction. Because of the high impact resistance and flexibility of HDPE pipe, it is well
suited to installation in dynamic soils including in earthquake-prone areas. HDPE pipe has very high flow
capacity, because of its smooth bore and end-to-end jointing methods. HDPE pipe does not corrode in the
environment, and will maintain its flow capabilities over time, unlike ferrous piping systems, which will rust and
build up internal resistance to fluid flowing through it.
