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.

Lubricant is then applied around the gasket as well as the internal surface of the pipe to ease installation.

When a watertight joint is necessary, the connection can be internally welded at human-entry diameters onsite. (Typically, these are over 900 mm diameter.)

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 1 bar and can be produced up to DN 900 mm, depending on the stiffness required. For SN 8 stiffness, the maximum diameter is 600 mm.

The socket-and-spigot is formed onto the end of the SRP pipe during the production process. A range of fittings will also be available with a rubber ring joint.

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.

Stormwater detention systems.

These watertight systems are custom-made to suit individual project requirements. To provide an effective system, we require details of the available tank area, depth and detention volume. Your solution may be similar to the three shapes below but we can also design and manufacture custom configurations.

We can incorporate a wide range of fittings such as bends, risers, blank ends and inlet/outlet pipes. 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.
