Used in indoor sewer installations for discharging domestic wastewater in gravity flow (non-pressure) conditions (where the leak-tightness test is performed at max. 0.5 bar), especially for building stacks, where attenuation of the sound produced by water discharge from upper floors is desired.
Reference standard: EN 1451.
The pipes, blast-furnace black in color, are made of PP with mineral additives, with a triple-layer wall construction, fitted at one end with a socket and gasket.
The size range includes diameters from 40 mm to 160 mm, with lengths between 250 and 3000 mm.
Acoustic performance is 16 dB at a flow rate of 2 l\/s. The sound-absorbing properties are certified based on measurements carried out 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 sewer systems, the following are recommended:
\u2022 Selecting a pipe and fittings system with good sound-absorbing properties;
\u2022 Proper system design;
\u2022 Correct installation of the system using suitable products. <\/p>\n","protected":false},"excerpt":{"rendered":"
