External sewer pipe MAGNAPLAST PCV-U 160 mm × 6000 mm, wall 4.0 mm, KGEM SN4, foamed

External sewer pipe MAGNAPLAST PCV-U 160 mm × 6000 mm, wall 4.0 mm, KGEM SN4, foamed is a rigid PVC-U drainage pipe intended for external underground wastewater systems. With a nominal diameter of 160 mm and a 6 m length, this sewer pipe is designed for gravity drainage applications in residential and light commercial installations. The 4.0 mm wall thickness and SN4 ring stiffness class provide sufficient structural support for typical surface loads, while the foamed (cellular) core improves thermal insulation and impact resistance compared with solid-wall pipes.

Advantages

The foamed PVC-U construction combines reduced weight with enhanced stiffness and thermal performance, making handling and installation easier without compromising durability. A smooth internal surface supports reliable flow and reduces the risk of blockages, and the standardized diameter and length simplify planning and connection to common sewer fittings. The SN4 rating indicates suitability for buried installations under pedestrian and light-vehicle loads where moderate ring stiffness is required.

Suitable for

• External underground gravity drainage systems for single-family homes and small buildings
• Connecting household wastewater outlets to municipal sewer networks or septic systems
• Replacement or upgrade of existing buried sewer runs with standard-dimension pipes

Key specifications

• Material: PVC-U (foamed / cellular core)
• Nominal diameter: 160 mm
• Length: 6000 mm
• Wall thickness: 4.0 mm
• Ring stiffness class: SN4 (suitable for pedestrian and light-traffic loads)
• Application: external underground gravity sewer

How to use

Select pipe alignment and bedding according to local installation standards and soil conditions. Excavate a trench with appropriate depth and width, provide a uniformly compacted or leveled bedding layer, and lay the MAGNAPLAST pipe with correct gradient for gravity flow. Use compatible couplings and seals for watertight connections and backfill in layers, compacting to avoid point loads. Verify pipe runs for correct slope and connections before final backfilling and surface restoration.

Usage recommendations

Use appropriate bedding and backfill materials to maintain ring stiffness and prevent deformation. Avoid exposing the pipe to prolonged sunlight before installation; store on a flat surface and protect from mechanical damage. For installations under traffic or heavy loads, consult applicable standards and consider higher ring stiffness classes or additional structural measures.
