These pipes are intended for indoor drainage systems, specifically for the discharge of domestic wastewater in gravity flow applications (where the leak test is performed at a maximum of 0.5 bar). They are particularly suitable for building risers where sound attenuation is desired for water flowing from upper floors.
Reference standard: EN 1451.
The black pipes are manufactured from 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 32 mm to 160 mm, with lengths between 250 mm 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 pipe clamps is recommended.
The fire behavior classification of the piping, in accordance with DIN 4102-1, falls under class B1. For penetration through ceilings, we recommend the use of fire collars as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, we recommend:
• Selecting a system of pipes and fittings with good sound-absorbing properties;
• Ensuring correct system design;
• Proper installation of the system using appropriate products.
