Used in interior sewage systems for the evacuation of domestic wastewater in gravity flow regime (where the tightness test is performed at max. 0.5 bar), where sound dampening from water discharge is desired.
Reference standard: EN 1451.
Black color, mass-colored, single-layer, made of PP with mineral additives.
Socket and gasket joining system, no special tools, adhesives or solvents required.
Size range includes diameters from 40 mm to 110 mm.
Acoustic performance is 16dB for a flow rate of 2 l\/s. Sound-absorbing properties are certified following measurements performed in the laboratories of the Fraunhofer Institute in Germany, according to EN 14366. The use of sound-absorbing clamps is recommended.
To reduce the noise level of interior sewage systems, it is recommended to:
\u2022 Choose a pipe and fitting system with good sound-absorbing properties;
\u2022 Ensure correct design of the installations;
\u2022 Properly install the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
