Used in indoor sewage systems for the evacuation of domestic wastewater in gravity flow regime (where the tightness test is performed at max. 0.5 bar), especially for building stacks, where sound dampening from water discharge from upper floors is desired.
Reference standard: EN 1451.
The pipes, in furnace black color, are made of PP with mineral additives, in triple-layer wall construction, fitted 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.
Acoustic performance is 16dB for a flow rate of 2 l\/s. Sound-absorbing properties are certified following measurements performed in the laboratories of the Fraunhofer Institute in Germany, according to EN 14366. The use of sound-absorbing clamps is recommended.
To reduce the noise level of indoor sewage systems, it is recommended to:
\u2022 Choose a system of pipes and fittings with good sound-absorbing properties;
\u2022 Ensure correct design of the installations;
\u2022 Correctly install the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
