It is used in internal drainage systems for the discharge of domestic wastewater under gravity flow (where the leak test is performed at max. 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 performed in the laboratories of the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
The fire behavior classification, in accordance with DIN 4102-1, is 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, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correctly installing the system using appropriate products.
