Twinwall Perforated Drain Pipe

Twinwall Perforated Drain Pipe for Surface Water Drainage

Twinwall drainage pipe made from HDPE plastic and is manufactured by twin extrusion process in which the two layers are simultaneously extruded one inside the other and heat welded together in one continuous step. The outer wall is corrugated providing excellent structural strength which reduces the possibility of on-site damage. The inner wall has a smooth seamless finish to assist hydraulic flow. The design unlike traditional single-wall pipe prevents silt accumulation.

Benefits

• Lightweight and available in long lengths (6m) making it quick and easy to install.
• Ease of installation and the elimination of wastage reduce labour and plant costs.
• Fewer joints and longer lengths (6m) assist flow.
• Resistant to most naturally occurring chemicals and is therefore suitable for use on the majority of soil conditions.
