It is used in internal drainage systems for the discharge of domestic wastewater under gravity flow conditions (where the leak test is performed at max. 0.5 bar), where sound attenuation produced by water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, made of PP with mineral additives.
Socket and gasket jointing system; no special tools, adhesives, or solvents are required.
The size range includes diameters from 40 mm to 110 mm.
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 clamps is recommended.
To reduce the noise level of internal drainage systems, we recommend:
\u2022 Selecting a pipe and fitting system with good sound-absorbing properties;
\u2022 Ensuring correct system design;
\u2022 Correctly installing the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
