Used in indoor sewerage installations for the discharge of domestic wastewater under gravity flow (for which the leak-tightness test is carried out at max. 0.5 bar), where sound damping of the noise produced by water discharge is required.
Reference standard: EN 1451.
They are black, mass-coloured, single-layer, made of PP with mineral additives.
Socket-and-gasket jointing system; no special tools, adhesives, or solvents are required.
Acoustic performance is 16 dB at a flow rate of 2 l/s. The sound-absorbing properties are certified following measurements carried out in the laboratories of the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
To reduce the noise level of indoor sewerage systems, it is recommended to:
• Choose a pipe and fittings system with good sound-absorbing properties;
• Ensure correct system design;
• Install the system correctly using suitable products.
