These pipes are utilized in internal drainage systems for the discharge of domestic wastewater under gravity flow conditions (where the leak test is performed at a maximum of 0.5 bar), particularly for building risers where sound attenuation from water discharge from upper floors is desired.
Reference standard: SR EN 1329-1.
The white pipes are manufactured by coextrusion from PVC-U with mineral additives, featuring a triple-layer wall construction, and are equipped with a socket and seal at one end.
The range of dimensions includes diameters from 50 mm to 200 mm, with lengths between 250 mm and 3000 mm.
The acoustic performance is 11 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 classification of the pipe’s fire behavior, in accordance with SR EN 13501, falls under class C \u2013 s3 \u2013 d0. The material is fire-resistant and self-extinguishing once the fire source is removed. Unlike other materials for internal drainage, fireproofing is not required as PVC-U is inherently fire-retardant. When passing through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of internal drainage systems, the following are recommended:
\u2022 Selecting a system of pipes and fittings 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":"
