Used in internal drainage systems for the discharge of domestic wastewater under non-pressure flow conditions (where the leak test is performed at a maximum of 0.5 bar), specifically where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, and made of PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
Socket and gasket jointing system; no special tools, adhesives, or solvents are required.
Acoustic performance is 16 dB for a flow rate of 2 L/s. The sound-absorbing properties are certified following measurements conducted in the laboratories of the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
Fire behavior classification, in accordance with DIN 4102-1, falls under class B1. When passing through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, the following are recommended:
• Selecting a system of pipes and fittings with good sound-absorbing properties;
• Ensuring correct installation design;
• Correctly installing the system using appropriate products.
