External sewage PVC-U pipe MAGNAPLAST 400 mm x 3000 mm, wall 11.7 mm, KGEL SN8 solid

MAGNAPLAST external sewage PVC-U pipe with a nominal diameter of 400 mm and a length of 3000 mm is designed for underground sewer and drainage applications. The pipe has a wall thickness of 11.7 mm and a solid KGEL SN8 construction that provides high stiffness and resistance to external loads. Made from corrosion-resistant PVC-U material, it is suitable for gravity drainage, stormwater conveyance and sanitary sewer systems where SN8 stiffness is required.

Advantages

The solid KGEL SN8 design delivers uniform stiffness and dimensional stability under typical burial conditions. The PVC-U material offers chemical and corrosion resistance, low maintenance needs and a smooth internal surface that supports efficient flow. The 3000 mm length and consistent wall thickness simplify installation and hydraulic calculations for continuous runs in gravity systems.

Suitable for

• Stormwater and surface runoff drainage
• Sanitary sewer gravity lines
• Underground drainage networks requiring SN8 stiffness
• Areas with moderate external loads such as vehicular traffic zones when installed to appropriate bedding standards

Key specifications

• Material: PVC-U (unplasticized polyvinyl chloride)
• Nominal diameter: 400 mm
• Length: 3000 mm
• Wall thickness: 11.7 mm
• Stiffness class: SN8 (solid KGEL construction)
• Construction: solid_wall pipe suitable for buried installation

How to use

Install the MAGNAPLAST 400 mm PVC-U pipe in accordance with local standards for buried sewerage and drainage systems. Prepare a stable bedding and backfill using suitable granular material; ensure correct alignment and gradient for gravity flow. Use compatible fittings and seals designed for PVC-U systems and verify joint integrity after assembly. Where surface loads are expected, follow manufacturer and local guidelines for cover depth and compaction to maintain SN8 performance.

Usage recommendations

Store pipes flat and supported to avoid deformation. Avoid prolonged exposure to direct UV radiation before installation. Confirm chemical compatibility for any transported fluids and consult local installation standards to ensure adequate bedding, cover and jointing for SN8-rated buried pipes.
