300/354mm Perforated Twinwall Pipe - 6m Length

This 300/354mm (ID/OD) perforated twinwall pipe is designed to collect and distribute surface water through perforations along the pipe wall. Acting as a filter drain, it channels water to a suitable collection point and is commonly used for roads and highways drainage applications.

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:

• 300mm drainage pipe suitable for collecting and distributing surface water.
• 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:

• Road drainage
• Highways drainage

Compatibility

This pipe is rigid, not flexible, and is intended for use with 300mm twinwall couplers or fittings to join two lengths of pipe together.

JDP offers a full range of compatible fittings and accessories, including fabricated fittings  manufactured in-house.

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.
