It is used in internal sewerage systems for the discharge of domestic wastewater under gravity flow (where the leak test is performed at a maximum of 0.5 bar), specifically where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, and made of PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
Socket and gasket jointing system; no special tools, adhesives, or solvents are required.
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.
The fire behavior classification, in accordance with DIN 4102-1, falls into class B1. When passing through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, it is recommended to:
\u2022 Choose a pipe and fitting system with good sound-absorbing properties;
\u2022 Ensure correct system design;
\u2022 Install the system correctly using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
