Utilized in internal sewage systems for the discharge of domestic wastewater in gravity flow (leak test up to 0.5 bar), where sound attenuation of water discharge is desired.
Reference Standard: EN 1451.
They are black, mass-colored, single-layer, made from 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. Sound-absorbing properties are certified following measurements conducted at 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 sewage systems, we recommend:
\u2022 Selecting a pipe and fitting system 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":"
