Plastream product range

Drainage pipes & fittings

All Plastream drainage pipes have a spigot end which can be inserted into the opposite end of the joining pipe.

A rubber gasket is used to seal the joint, making it suitable for gravity systems where a soil- or silt-tight joint is required, up to DN900.

Above DN900 the connection can be internally extrusion welded onsite.

Plastream pipe is compatible with a full range of fabricated fittings such as bends, elbows, tees, slope junctions and reducers. Both standard and custom fittings can be readily manufactured. Elbows and bends of any angle can be provided and large diameter fittings can be custom-made to function as maintenance holes and pits.

Sewer pipe & fittings (coming soon)

Plastream pipe will soon be available for sewer applications through the application of socket-and-spigot rubber ring joints. These joints are capable of pressures up to 0.74 bar and can be produced up to DN 600 mm, depending on the stiffness required.

The socket-and-spigot design is injection moulded.

Subsoil drainage pipes.

Plastream can also be produced as perforated pipe for a variety of drainage applications. Rectangular slots (dimensions of 3 mm x 9 mm) are punched into the wall of the pipe, providing a total perforated area of 2.1%. The even distribution of these slots around the pipe allows for uniform outflow of water, thus reducing the possibility of any differential movement of surrounding soil due to uneven moisture content. The ribbed configuration combined with the small perforations prevents large soil particles from entering the pipeline. However, in sandy or fine soil conditions, geotextile fabric may be required.

Inground Detention Systems.

Plastream Detention Systems are used as stormwater detention systems and sewerage overflow systems. The systems are available from DN900 to DN2250. The watertight detention systems are custom-made to suit individual project requirements.

The systems can be manufactured as individual sections in sizes, lengths and configurations that can be economically transported and then assembly can be completed onsite. Again, the light weight of these sections and their ease of handling, even at large diameters, along with the simplicity of polyethylene welding allows final fabrication of the tanks onsite.
