It is used in internal drainage systems for the discharge of domestic wastewater under gravity flow (where the leak test is performed at max. 0.5 bar), especially for building stacks, where sound attenuation 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 size range includes diameters from 32 mm to 160 mm, with lengths between 250 mm and 3000 mm.
The acoustic performance is 16 dB for a flow rate of 2 l\/s. The sound-absorbing properties are certified following measurements conducted at the Fraunhofer Institute laboratories 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, falls under class B1. For protection against flame propagation when passing through ceilings, we recommend using fire-resistant clamps.
To reduce the noise level of internal drainage systems, the following are recommended:
\u2022 Selecting a pipe and fitting system with good sound-absorbing properties;
\u2022 Ensuring correct system design;
\u2022 Correct installation of the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
