It is used in internal drainage systems for the discharge of domestic wastewater in gravity flow applications (where the leak test is performed at a maximum of 0.5 bar), particularly where sound attenuation of water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, 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.
The 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, 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 the use of fire collars as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, the following are recommended:
• Choosing a pipe and fitting system with good sound-absorbing properties;
• Implementing a correct design of the installations;
• Correct installation of the system using appropriate products.
