MAGNAPLAST external sewer pipe KGEM with bell-and-spigot, foamed core, class C, Ø160 mm, 1 m

MAGNAPLAST external sewer pipe KGEM with bell-and-spigot, foamed core, class C, Ø160 mm, 1 m is a rigid underground drainage pipe designed for wastewater and stormwater conveyance. The pipe features a foamed (cellular) core that reduces weight while retaining stiffness, and a bell-and-spigot connection that enables quick, sealed joints for linear runs and manhole connections. Intended for external sewer networks, the product meets class C load requirements for buried installations and is supplied in 1 m lengths for modular assembly on site.

Advantages

The foamed core construction combines reduced material usage with improved thermal and acoustic insulation compared to solid-wall alternatives, while maintaining the structural rigidity required for buried pipelines. The bell-and-spigot end simplifies jointing and alignment, allowing a uniform seal without additional external fittings. Class C load rating provides adequate resistance to typical ground loads in non-traffic or light-traffic burial conditions. The 160 mm nominal diameter supports common domestic and small commercial drainage flows.

Suitable for

• External underground wastewater and stormwater lines
• Site sewer branches and lateral connections
• Connections to manholes and inspection chambers
• Drainage systems for residential and light commercial properties

Key specifications

• Nominal diameter: 160 mm
• Length: 1 m
• Pipe type: rigid external sewer pipe with bell-and-spigot connection
• Core structure: foamed (cellular) core
• Load class: C (suitable for buried installations with typical ground loads)
• Application: underground wastewater and stormwater conveyance

How to use

Install the MAGNAPLAST KGEM pipe in a prepared trench with appropriate bedding and backfill materials according to local standards. Ensure mating pipe ends are clean and undamaged before insertion; lubricate seals if required by the sealing system manufacturer. Push the spigot fully into the bell to engage the joint and verify correct alignment and slope for gravity drainage. Place supports or temporary braces during assembly to maintain line and grade, and compact surrounding fill in layers to achieve the designed load-bearing conditions.

Usage recommendations

Follow prevailing national and local installation standards for sewer pipelines, including requirements for bedding, cover depth, jointing, and testing. Avoid exposing pipe sections to UV light for prolonged periods prior to installation. For installations near traffic routes or heavy loads, verify that class C load rating is sufficient or select a higher load class. Use compatible seal materials and accessory components recommended for bell-and-spigot sewer systems.
