Product Data

Flood Pipe Polyethylene (PE) Pipe is manufactured to the dimensions and dimensional tolerances of Series 1, SDR 41 pipe complying with AS/NZS 4130:2009.

Standard pipe lengths can be supplied to lengths of 12.0-20.0 metres.

Rural pipe is intended for use under conditions where the maximum operating pressure does not exceed 600 kPa at 20°C.

Metric pipes are used for numerous applications, some of which include domestic water supply, mine services and irrigation.

Flood pipe is intended for use under flow conditions where the maximum operating pressure does not exceed 250 kPa at 20°C. Flood pipe should not be used where sub atmospheric service pressures less than minus 12 kPa.

Poly Pipe Pty Ltd (Poly Pipe) supplies PE pipe that can be joined using compression fittings, electrofusion systems or butt-welding.

Expansion & Contraction

PE pipe will expand and contract by approximately 250mm for every 100m of pipe over a 10°C change in pipe temperature.

For below ground installations, no allowance for expansion is required provided the connection system has stabilised to service temperature before backfilling.

In above ground installations, thermal contraction is allowed for by ‘snaking’ the pipe.

Design Life

PE Pipe is manufactured in accordance to Australian Standard AS/NZS 4130:2009 - Polyethylene (PE) pipes for pressure applications.

By convention, PE pipe is often designed on the basis of 50 year life. This is established international practice but is not intended to imply the service life of pressure pipe is limited to 50 years.

For correctly manufactured and installed systems, the actual life cannot be predicted, but can be expected to be well in excess of 100 years before major rehabilitation is required.
