External sewer pipe MAGNAPLAST 110 mm x 6000 mm PVC-U foam SN8

MAGNAPLAST external sewer pipe with a 110 mm diameter and 6000 mm length is a foam-structured PVC-U pipe engineered for underground drainage and external sewage networks. The foam core construction combines a lightweight design with increased stiffness, meeting SN8 stiffness class requirements for applications that need resistance to vehicular and soil loads. The smooth interior facilitates flow for collectors, stormwater and gravity drainage systems while the robust outer shell provides mechanical protection in buried installations.

Advantages

The PVC-U foam structure delivers a favorable strength-to-weight ratio, simplifying handling and transport without sacrificing structural performance. SN8 stiffness ensures the pipe withstands static and transient loads from traffic and overburden when installed at the recommended depths. The smooth bore reduces friction and sediment build-up, supporting reliable hydraulic performance. Corrosion-resistant PVC-U material increases durability in varied soil conditions and minimizes maintenance needs compared with some metallic alternatives.

Suitable for

• Underground external sewage mains and collector lines
• Stormwater drainage and surface water conveyance
• Gravity-fed sewer systems
• Applications requiring SN8 stiffness for vehicular load zones

Key specifications

• Material: PVC-U with foam-structured core
• Nominal diameter: 110 mm
• Length: 6000 mm
• Stiffness class: SN8 (suitable for traffic and overburden loads when installed correctly)
• Profile: smooth internal bore for efficient flow
• Application: external underground drainage and sewer networks

How to use

Install the pipe in a prepared trench with appropriate bedding and backfill according to local standards and the project’s structural requirements. Ensure jointing is performed with compatible fittings and seals to maintain hydraulic tightness and prevent infiltration or exfiltration. Follow recommended installation depths and load distribution measures for SN8-class pipes, including compaction of backfill and placement of bedding material to avoid point loads. Periodic inspection after installation can verify alignment and joint integrity.

Usage recommendations

Select trench bedding and backfill materials that provide uniform support along the pipe length and avoid sharp stones or debris that could damage the outer shell. Use proper jointing accessories rated for PVC-U and SN8 applications, and adhere to local regulations for frost protection and minimum cover depth. For long runs, plan for expansion allowance and consider access points for maintenance of stormwater and collector lines.
