Used in interior 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, black in 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 32 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 performed in the laboratories of the Fraunhofer Institute in Germany, according to EN 14366. The use of sound-absorbing clamps is recommended.
The fire behavior classification of the piping in accordance with DIN 4102-1 is class B1. When passing through ceilings, we recommend using fire-stop collars as a protective measure against flame propagation.
To reduce the noise level of interior sewage systems, it is recommended to:
• Choose a system of pipes and fittings with good sound-absorbing properties;
• Ensure correct design of the installations;
• Correctly install the system using appropriate products.
