This product is used in internal drainage systems for the discharge of domestic wastewater under non-pressure flow conditions (with a leak test performed at a maximum of 0.5 bar), specifically where sound attenuation of water discharge is required.
Reference standard: EN 1451.
These are black, mass-colored, single-layer products made from PP with mineral additives.
The connection system uses a socket and gasket; no special tools, adhesives, or solvents are required.
The acoustic performance is 16 dB for a flow rate of 2 l/s. The sound-absorbing properties are certified following measurements conducted at the Fraunhofer Institute laboratories in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
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 system design;
• Installing the system correctly using appropriate products.
