External sewer pipe MAGNAPLAST 250 mm × 2000 mm PVC-U SN8 solid wall

MAGNAPLAST external sewer pipe in PVC‑U is a solid wall conduit with a nominal diameter of 250 mm and a length of 2000 mm. Manufactured for use in surface and underground drainage systems, this SN8 stiffness class pipe is intended for installations that require enhanced ring stiffness to withstand soil and traffic loads. The product is suitable for stormwater conveyance, gravity sewer runs and open trench installation when combined with appropriate jointing and bedding materials.

Advantages

The solid wall design delivers uniform structural strength and corrosion resistance typical of PVC‑U, providing long-term durability in aggressive soils and standard wastewater environments. SN8 ring stiffness ensures the pipe maintains shape under higher external loads and compaction pressures, reducing deformation risks during service life. Smooth internal surface promotes efficient flow and reduces sediment accumulation, while the 2000 mm length balances handling convenience and reduced joint count on site.

Suitable for

• Surface and buried stormwater drainage systems
• Gravity sewer runs in residential and commercial developments
• Open trench installations with appropriate bedding and jointing
• Areas requiring higher ring stiffness due to traffic or deep cover

Key specifications

• Material: PVC‑U (unplasticized polyvinyl chloride)
• Nominal diameter: 250 mm
• Length: 2000 mm
• Wall type: solid wall
• Ring stiffness class: SN8
• Internal surface: smooth for improved flow characteristics
• Application: external sewer and stormwater drainage

How to use

Install MAGNAPLAST 250 mm sewer pipe in prepared trenches with a compacted or decompacted bedding layer according to local installation standards. Ensure pipe alignment and gradient are correct for gravity flow before jointing. Use compatible gasketed or solvent-weld joints as specified by the project and manufacturer instructions. Backfill in layers with appropriate material and compaction to achieve uniform support and to protect against point loading; observe recommended cover depths for SN8 pipes in trafficked areas.

Usage recommendations

Verify site-specific requirements such as frost depth, traffic load, and chemical exposure prior to installation. Use manufacturer-recommended gaskets and jointing procedures, and follow national codes for bedding, backfilling and compaction to preserve the SN8 performance. For stormwater with high debris load, consider access points for inspection and maintenance.
