Internal sewer pipe MAGNAPLAST 160 mm x 3000 mm PP gray

MAGNAPLAST internal sewer pipe is a rigid polypropylene (PP) pipe with a nominal diameter of 160 mm and a length of 3000 mm in gray. It is designed for internal wastewater and drainage systems in residential and commercial buildings. The smooth inner surface and corrosion-resistant PP material ensure stable flow and long service life when used as part of vertical stacks, branch lines or horizontal drainage runs.

Advantages

The PP construction offers chemical resistance to typical household and commercial wastewater, while the rigid design maintains dimensional stability under normal loading and temperature ranges. The smooth bore reduces the risk of blockages and sediment buildup. The 3 m length reduces the number of joints required on longer runs, simplifying installation and lowering potential leak points. The neutral gray finish is suitable for concealed and visible installations in technical spaces.

Suitable for

• Internal vertical soil and waste stacks in multi-storey buildings
• Horizontal drainage runs within basements, service ducts and crawl spaces
• Connecting toilets, sinks, showers and floor drains to the building drainage system
• Renovation projects where replacement of existing 160 mm sewer lines is required

Key specifications

• Material: polypropylene (PP)
• Nominal diameter: 160 mm
• Length: 3000 mm
• Colour: gray
• Rigid pipe designed for internal wastewater and drainage systems

How to use

Measure and plan the layout to minimise the number of cuts and joints. Cut the pipe square using an appropriate pipe cutter or saw, deburr the edges and check fit with compatible fittings and seals designed for PP sewer systems. Assemble pipe and fittings according to the fitting manufacturer’s instructions, ensuring correct alignment and adequate support at recommended spacing. Use appropriate sealing elements or solvent/heat-fusion methods only if specified for the selected fittings and local regulations. Test the assembled system for leaks and proper flow before closing walls or ducts.

Usage recommendations

Store pipes horizontally on a flat surface to avoid deformation and protect from prolonged direct sunlight. Use suitable supports and clamps to prevent excessive deflection; follow local building codes for support intervals. Avoid exposure to open flames or high temperatures beyond polypropylene’s service range. For installations with unusual chemical exposure or high temperature effluents, verify material compatibility before use.
