PE Sewer Pipe Systems

PE sewer pipe and fittings are manufactured to AS/NZS 4130 using PE100 high density polyethylene material that is co-extruded with a dark external colour and a white/light internal colour. This system is designed specifically for the waste water industry and is best suited to gravity sewer and drainage applications.

The dark external layer (black/white stripe or dark grey) provides impact and UV resistance, while the white/light coloured internal layer provides good reflection for manual and video inspection purposes.

Sewer fittings are factory fabricated and welded using PE sewer pipe and moulded fittings as required.

The spigot ended pipes and fittings are joined by fusion welding, to ensure a fully sealed system, using either the butt-weld or electrofusion processes.

FABRICATION AND INSTALLATION

Materials:
PE Sewer fittings shall be manufactured using PE pipes and moulded fittings that conform to AS/NZS 4129 and AS/NZS 4130.

Range:
The fittings range and configurations must comply with the requirements of the local authority and WSAA.

Factory Welds:
Butt weld and electrofusion are approved processes; and extrusion hot air welding (when BW and EF in not possible)

Site Welds:
Butt weld and electrofusion are approved processes.

Installation:
All factory and site welding to be performed by an accredited butt and electrofusion welder. Refer to requirements of the local authority.
