It is used in internal sewage systems for the discharge of domestic wastewater in gravity flow mode (where the leak test is performed at a maximum of 0.5 bar), especially for building stacks, where sound dampening 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.
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 internal drainage systems, we recommend:
\u2022 Selecting a system of pipes and fittings with good sound-absorbing properties;
\u2022 Ensuring correct system design;
\u2022 Correct installation of the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
