MAGNAPLAST external sewer pipe PCV-U 160 mm x 500 mm × 4.7 kg/m SN8 solid

MAGNAPLAST external sewer pipe PCV-U 160 mm x 500 mm × 4.7 kg/m SN8 solid is a rigid underground drainage element designed for external sewage and stormwater systems. The pipe has a nominal diameter of 160 mm and a 500 mm length with a solid wall and SN8 stiffness class, providing dimensional stability under soil cover and vehicular loads. It is intended for gravity drainage runs, connecting to manholes and surface network pipelines where high stiffness and consistent geometry are required.

Advantages

This MAGNAPLAST PCV-U pipe combines a solid, smooth bore with high ring stiffness (SN8), ensuring resistance to deformation from earth and traffic loads while maintaining hydraulic capacity. The material offers chemical resistance typical of PVC-U, low weight relative to traditional materials, and ease of handling and installation. Uniform dimensions and surface finish support reliable jointing and long-term performance in buried drainage applications.

Suitable for

• Underground gravity sewage and stormwater pipelines
• Connections between surface network runs and manholes
• Areas requiring high ring stiffness under vehicle loads
• New installations and replacement sections in external drainage systems

Key specifications

• Nominal diameter: 160 mm
• Length: 500 mm
• Wall type: solid
• Mass: 4.7 kg/m
• Stiffness class: SN8 (high ring stiffness)
• Material: unplasticized PVC (PVC-U)

How to use

Install the MAGNAPLAST PCV-U external sewer pipe in accordance with applicable local regulations and best-practice guidelines for buried drainage systems. Prepare a suitable trench bed with appropriate bedding material and compaction to support the pipe along its length. Align pipe ends accurately and use compatible couplings or gaskets as specified by the system design to ensure watertight joints. Backfill in layers with controlled compaction to avoid point loads or deformation, and verify gradient for gravity flow.

Usage recommendations

Verify site-specific requirements such as bedding class, cover depth, and traffic loading before selecting this SN8 pipe. Use compatible fittings and jointing methods recommended for PVC-U systems and follow manufacturer or local standards for installation, testing, and inspection to ensure long-term performance.
