An unperforated plain ended twin wall pipe, manufactured from recycled HDPE. Utilising a twin extrusion process, 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. Collar and ring seals sold separately. Inside diameter 450mm Outside diameter 512mm Length 6 metre Show more
