It is used in indoor sewage systems for the discharge of domestic wastewater in non-pressure flow (where the leak test is performed at max. 0.5 bar), in applications where sound attenuation of water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, 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, falls into class B1. When passing through ceilings, we recommend the use of fire-resistant pipe clamps as a protective measure against flame propagation.
To reduce the noise level of indoor drainage systems, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correct installation of the system using appropriate products.
