Used in indoor sewer installations for draining domestic wastewater in gravity flow (non-pressurized) conditions (where the leak-tightness test is performed at max. 0.5 bar), especially for building stacks, where sound damping from water discharge from upper floors is required.
Reference standard: EN 1451.
The pipes, black in color, are made of PP with mineral additives, with a triple-layer wall construction, fitted at one end with a socket and gasket.
The size range includes diameters from 32 mm to 160 mm, with lengths between 250 and 3000 mm.
Acoustic performance is 16 dB at a flow rate of 2 l/s. The sound-absorbing properties are certified based on measurements carried out 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 of the piping in accordance with DIN 4102-1 is class B1. When passing through ceilings, we recommend using fire collars as a flame-spread protection measure.
To reduce the noise level of indoor sewer systems, the following are recommended:
• Choosing a pipe and fittings system with good sound-absorbing properties;
• Proper system design;
• Correct installation of the system using suitable products.
