94/110mm Perforated Twinwall Pipe - 6m Length

This 94/110mm (ID/OD) perforated twinwall pipe is designed to collect and distribute surface water through perforations along the pipe wall. Commonly used in agricultural drainage systems as a filter drain, this rigid twinwall pipe is supplied in 6m lengths and comes complete with a pre-fitted 110mm coupler for efficient installation.

Manufactured from HDPE using a twin extrusion process, the pipe combines a robust corrugated outer wall with a smooth inner wall to support efficient hydraulic performance.

Features & benefits include:

• 110mm drainage pipe suitable for collecting and distributing surface water.
• Comes with a pre-fitted 110mm coupler attached to the pipe.
• Perforated design allows water to enter the pipe for effective drainage.
• Lightweight construction for easier handling and transportation.
• Quick installation helps reduce plant and labour requirements on site.
• Corrugated external wall provides strength whilst maintaining a low overall weight.
• Smooth internal bore assists hydraulic performance and flow efficiency.
• Design helps minimise the accumulation of silt within the pipe.
• Can be cut on site using conventional hand tools when required.
• Suitable for use in a wide range of soil conditions.
• Compatible with a range of 150mm twinwall fittings and accessories.
• Manufactured from HDPE and compliant with HAPAS/BBA requirements.

Product Details

Perforated twinwall pipes are designed with small holes (perforations) in each dwell along the pipe length to collect and distribute surface water. This makes them suitable for use as filter drains, directing water to a suitable collection point.

The twin extrusion manufacturing process used to create these pipes gives them a corrugated outer wall, making them more resilient to external pressure and weight loads, and a smooth inner wall to assist hydraulic flow and minimise silt build-up by removing the internal dwells of single-wall corrugated pipes.

Twinwall pipes typically weigh less than 6% of the equivalent size of concrete pipe, while still retaining a strength and durability sufficient for most drainage applications. This lightweight design makes them easier to transport and safer to handle on site.

Applications

Twinwall pipes of this diameter are most commonly used in:

• Farm drainage
• Field drainage

Compatibility

This pipe is rigid, not flexible, and comes with a pre-fitted 110mm coupler attached to join to other lengths of pipe.

Standard orange 110mm drainage fittings and junctions are required to create a system with this type of twinwall.

Half perforated pipe is also available upon request.

Installation Advice

Twinwall pipes are suitable for installation in a wide range of soil conditions and can be easily cut on site using conventional hand tools. Where site modifications are required, pipes should be cut square between corrugations for best results.
