Fully Perforated Pipe - Twinwall

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. Available in black as standard.

Features & Benefits:

·         Flow rates of up to 0.75 meters/second (Gradient of 1: 100)

·         Compression strength of 750 N

·         Up to 50% more efficient than single wall coil

·         Smooth internal plastic bore with reduced hydraulic resistance. Manning’s coefficient of 0.012 allows for greater flow capacity and also a greater factor of safety. This also reduces sediment or debris build-up when compared to concrete or steel.

·         Lightweight when compared to traditional materials such as concrete or steel. (Up to 90% lighter than concrete)

·         Fully leak tested to HAPAS requirements when used with rubber seals.

·         Standard 6m lengths make it quick and easy to install, eliminating wastage and reduces labour and plant costs. (Up to 6 times faster installation compared to concrete)

·         Parallel corrugations allow pipe to be easily cut square on site as required. (Spiral wound pipe makes it very difficult to create a square cut on site if required)

·         JFC CorriPipe™ is available unperforated, fully perforated or half perforated.

·         Manufactured  from exceptionally durable HDPE material with excellent corrosion resistance and long term performance.

·         Resistant to most naturally occurring chemicals and is therefore suitable for use on the majority of soil conditions.
