What is an acoustic piping system?
An acoustic piping system such as SereneTech is a specialized drainage solution designed to dampen and reduce the noise generated by wastewater flowing through a building’s plumbing.Unlike standard pipes, these systems utilize advanced materials and multilayer construction to minimize both airborne noise (sound traveling through the air) and structure-borne vibrations (sound transferring into the building’s walls).
How does the SereneTech Acoustic Pipe System reduce drainage noise?
The SereneTech Acoustic Pipe System uses a three-layer co-extruded design to block noise. The critical component is the middle layer, which is made of mineral-filled polypropylene (PP-MD). This layer adds high density and mass to the pipe, which effectively dampens sound vibrations and prevents them from escaping the pipe.Additionally, the system uses “swept” branches to reduce turbulence (a common source of noise) and specialized acoustic brackets to decouple the pipe from the building structure.
What materials are used in the SereneTech and SereneTech+ systems?
The pipes consist of three distinct layers co-extruded together:
- Inner layer: Made of Polypropylene Block Copolymer (PP-B) for chemical resistance and smooth flow.
- Middle layer: Made of mineral-filled Polypropylene (PP-MD) for sound absorption and high density.
- Outer layer: Made of PP-B for structural strength and impact resistance.
- Fittings: Molded from mineral-filled polypropylene (PP-M).
Where can acoustic drainage pipes be used?
Acoustic drainage pipes are suitable for a wide range of residential, commercial and critical environment applications, including:
- Residential: High-rise buildings, luxury apartments, and villas.
- Commercial: Offices and educational institutions.
- Critical environments: Hospitals, hotels, and nursing homes where silence is prioritized.
- They can be used for soil, waste, and rainwater drainage systems.
Are SereneTech pipes compliant with international standards?
Yes. The system complies with numerous international standards, including:
- EN 1451 & DIN 19560: For soil and waste discharge systems.
- DIN 4109 & VDI 4100: For sound insulation in buildings.
- EN 14366: Laboratory measurement of noise.
- DIN 4102: Fire behavior classification.
Can the SereneTech system handle high-temperature wastewater?
Yes, the SereneTech system can handle high-temperature wastewater. This multi-layer piping system is designed to withstand continuous wastewater temperatures of 90°C (194°F) and intermittent temperatures up to 95°C (203°F). This makes SereneTech suitable for discharge from washing machines and dishwashers.
How are SereneTech acoustic pipes installed?
The pipes use push-fit socket joints equipped with EPDM elastomeric sealing rings. This allows for fast installation without the need for solvent cements or glues.
- A specific lubricant (PolyLube) is used to ease the insertion of the spigot into the socket.
- Installation requires specific acoustic bracketing rules (using fixed and sliding brackets) to accommodate thermal expansion and prevent vibration transfer.
Are SereneTech pipes suitable for underground installation?
Yes. The SereneTech system is suitable for Application Area B (anchored externally) and for being buried underground or laid directly in concrete.
What are the benefits of using acoustic drainage systems in buildings?
Using acoustic drainage systems in buildings offers the following benefits:
- Noise reduction: Creates a quieter, more comfortable environment for occupants.
- Durability: High resistance to abrasion and environmental stress cracking.
- Chemical resistance: Capable of withstanding aggressive chemicals with a pH range of 2 to 12.
- Sustainability: Made from recyclable materials with a design life expectancy of 50 years.
What is the difference between SereneTech and SereneTech+?
SereneTech (Standard): Designed for residential and office use, offering noise attenuation levels up to 16 dB.
SereneTech+ (High Performance): Designed for hospitals and hotels, offering superior performance with noise attenuation levels up to 12 dB (indicating a quieter resulting noise level). It features a thicker wall structure compared to the standard version.
Are acoustic drainage pipes more durable than standard PVC pipes?
Yes, SereneTech acoustic drainage pipes are more durable than standard
PVC pipes. In comparative studies, SereneTech materials are rated as having
higher resistance to abrasion and weathering than standard PVC. SereneTech also has a higher resistance to external impact and tension.
Why are mineral-filled polypropylene layers used in acoustic pipes?
The mineral filler for polypropylene acoustic pipes increases the density of the material (up to < 1.9 g/cm³). In acoustics, mass blocks sound. By increasing the weight of the pipe without significantly increasing its size, the mineral-filled layer effectively absorbs sound waves and reduces the transmission of noise generated by the water flow.
Do acoustic drainage systems require special maintenance?
The SereneTech system is generally low maintenance due to its smooth inner layer, which prevents buildup. However, like all drainage systems, it requires accessible points for inspection and cleaning.
