Twinwall pipe up to 600mm
TwinWall Surface Water Drainage
Drainstore offer a complete system of TwinWall Drainage, which is a structured wall pipe and is the complete technical and commercial answer to all non-pressure, surface and sub-surface water drainage applications. TwinWall pipes have been installed on thousands of civil engineering projects including highway, rail and airport infrastructure projects.
TwinWall is manufactured by a twin extrusion process. TwinWall comprises of two HDPE (high density polyethylene) pipes which are extruded simultaneously, one inside the other, and heat welded together in one continuous process.
The pipes are black in colour, the outer wall being corrugated and the inner wall having a smooth finish to assist the hydraulic flow. A comprehensive rang of push fit fittings and sealing rings are also available for each diameter. TwinWall pipes are available in carrier, fully perforated and solid invert configuration. TwinWall is approved for roads and building. For an even more comprehensive rang including sizes up to 1050mm please see the Civil Engineering & Utilises product specifier book.
Features and benefits
- Full Range from 100 to 1050mm.
- Fewer joints means faster installation and less potential for leakage.
- Structured wall design for high ring stiffness.
- Optimised weight for reduced health and safety risks and ease of transport, handling and installation.
- TwinWall pipes have a weight less than 6% of the equivalent size of concrete pipe.
- Strong yet flexible design allows pipeline to withstand some ground movement and differential settlement.
- Robust, impact and abrasion resistant construction.
- Low friction inner wall for superior hydraulic performance.
- Integral sockets available in diameters 150mm to 900mm
