MAGNAPLAST low-noise sewer pipe UdBEM 160x4.9x3000 ULTRA-dB blue

MAGNAPLAST low-noise sewer pipe UdBEM 160x4.9x3000 ULTRA-dB blue is a rigid drainage pipe engineered for wastewater and sewer systems where acoustic performance and reliable waste transport are required. The pipe combines a nominal diameter of 160 mm, a 4.9 mm wall thickness and a 3.0 m length in a blue ULTRA-dB design that reduces sound transmission compared with standard rigid sewer pipes. It is intended for indoor and underground drain runs in residential and light-commercial buildings.

Advantages

The design focuses on reduced noise propagation from flowing wastewater and discharge events, helping to lower audible sound in adjacent rooms and service spaces. Its rigid construction and consistent wall thickness provide mechanical strength for buried runs and building installations, while the ULTRA-dB concept integrates sound-damping material or geometry to attenuate impact and flow noise. The 160 mm diameter allows for higher flow capacity than smaller domestic drains and supports common household and multi-unit building drainage layouts.

Suitable for

• Wastewater and sanitary sewer branches in residential buildings
• Drainage lines in multi-family dwellings and small commercial premises
• Hidden or exposed vertical and horizontal runs where acoustic performance matters
• Buried or enclosed drains requiring a rigid, dimensionally stable pipe

When it may not be suitable

This rigid 160 mm MAGNAPLAST pipe is not intended for pressurized water mains or systems requiring flexible coupling for large differential movement; it is designed for gravity drainage. It may be unnecessary for installations where noise is not a concern or where smaller-diameter, more economical pipes are acceptable.

Key specifications

• Nominal diameter: 160 mm
• Wall thickness: 4.9 mm
• Length: 3000 mm (3.0 m)
• Acoustic design: ULTRA-dB low-noise construction
• Colour: blue
• Application: wastewater and sewer drainage
• Material: rigid sewer pipe construction (acoustic-optimized)

How to use

Install MAGNAPLAST UdBEM 160x4.9x3000 ULTRA-dB as part of a gravity drainage system following local plumbing codes and best practices. Cut to length where required, deburr end faces and connect using compatible solvent-weld or gasketed fittings specified for UdBEM product range. Ensure proper fall and alignment, support the pipe at recommended intervals, and seal joints as instructed by the manufacturer to maintain acoustic and hydraulic performance. Verify connections to traps, stacks and inspection chambers to avoid leaks and noise paths.

What to consider before purchase

• Confirm required nominal diameter (160 mm) and that 3.0 m lengths suit transport and installation access
• Check compatibility with existing fittings, junctions and stack connections in the installation
• Ensure the acoustic ULTRA-dB version meets project sound insulation requirements
• Verify local code requirements for buried depth, bedding, and backfill when used underground

Usage recommendations

To achieve optimal acoustic results, combine the ULTRA-dB pipe with properly sealed junctions, acoustic supports or insulation where pipes pass through walls or floors. Regular inspection after installation helps ensure joints remain watertight and sound attenuation performs as intended.
