MAGNAPLAST PIPE EXTERNAL D110 SN4 1.0M 3.2MM — external drainage pipe, 110 mm, SN4, length 1.0 m, wall 3.2 mm

MAGNAPLAST PIPE EXTERNAL D110 SN4 1.0M 3.2MM is an external drainage pipe with a nominal diameter of 110 mm, designed for surface and subsurface stormwater management. The pipe combines a 3.2 mm wall thickness with a stiffness class SN4 to provide a balance of structural stability and manageable weight for trench installation in residential and light commercial drainage systems. Its 1.0 m length allows straightforward handling, cutting and connection to existing networks and fittings.

Advantages

The pipe offers corrosion-resistant plastic construction that resists typical soil and water conditions, reducing the need for frequent replacement. Its SN4 stiffness class provides sufficient rigidity for buried applications under standard backfill conditions while remaining flexible enough for alignment and coupling during installation. The standard 110 mm diameter supports common drainage flow rates and is compatible with a wide range of fittings and connectors used in site drainage and stormwater systems.

Suitable for

• Surface and subsurface drainage of stormwater and runoff
• Trench installation and connection to existing drainage networks
• Residential yards, gardens and light commercial sites
• Soil water management and conveyance of stormwater to retention or discharge points

Key specifications

• Nominal diameter: 110 mm
• Stiffness class: SN4
• Length: 1.0 m
• Wall thickness: 3.2 mm
• Material type: durable corrosion-resistant plastic

How to use

Select compatible couplings and fittings sized for 110 mm nominal diameter. Cut the pipe to required lengths if necessary and prepare ends for solvent or push-fit connections following the fitting manufacturer’s instructions. Place the pipe in a prepared trench with appropriate bedding and backfill material; ensure alignment and slope to achieve required drainage flow. Verify joint tightness and protect exposed sections from prolonged UV exposure if left above ground temporarily.

Usage recommendations

Use appropriate bedding and backfill to meet local standards for buried drainage pipes. Avoid heavy concentrated loads above the pipe without additional structural protection. For installations with unusual loads or soil conditions, consult an engineer to confirm suitability of SN4 stiffness class and select higher stiffness or protective measures if required.
