This pipe is used in internal drainage systems for the discharge of domestic wastewater under gravity flow conditions (where the tightness test is performed at a maximum of 0.5 bar), particularly for building stacks where sound dampening of water discharge from upper floors is desired.
Reference standard: EN 1451.
The black pipes are made of PP with mineral additives, featuring a triple-layer wall construction, and are equipped with a socket and gasket at one end.
The range of dimensions 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 by 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 fire propagation protection when passing through ceilings, we recommend using fire collars.
To reduce the noise level of internal drainage systems, the following are recommended:
• Selecting a system of pipes and fittings with good sound-absorbing properties;
• Ensuring correct design of the installations;
• Correctly installing the system using appropriate products.
