It is used in indoor drainage systems for the discharge of domestic wastewater in gravity flow (where the leak test is performed at max. 0.5 bar), especially for building stacks, where sound attenuation of water discharge from upper floors is desired.
Reference standard: EN 1451.
The pipes, in furnace black, are made of PP with mineral additives, featuring a triple-layer wall construction, and are equipped with a socket and gasket at one end.
The size range includes diameters from 40 mm to 160 mm, with lengths between 250 and 3000 mm.
The acoustic performance is 16 dB for a flow rate of 2 l\/s. The sound-absorbing properties are certified following measurements conducted 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 indoor drainage systems, we recommend:
\u2022 Selecting a system of pipes and fittings with good sound-absorbing properties;
\u2022 Ensuring correct system design;
\u2022 Proper installation of the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
