Peštan silent piping system is a promoted version of Peštan HTPP home sewage system and it is specially designed for installation in places where sound insulation is taken into account. Installed with special pipe clamps (with profiled rubber ring) provides reduction in noise an acoustic vibrations up to level of 12 dB*. The latest technology of three-layer extrusion pipe and materials modified with mineral additives have raised disposal of waste water systems within the building structure on a higher level. Production program Peštan S LINE pipes for the installation of sewage systems inside buildings includes pipes produced from high quality polypropylene-copolymer (PP-C) hardened mineral additives, in technology, three-layer composite pipes according to the requirements of EN 1451, in diameters from Ø32 to Ø160.


Complete program Peštan S LINE pipes and fittings for sewerage inside buildings resistant to constant heat load of + 60 ° C, as well as shortterm thermal load of + 95 ° C.


The density of 9 g / cm3, according to ISO 1183 Tensile strength of 28 MPa according to ISO 527 Modulus of stretching 1,300 MPa according to ISO 527 Impact strength according to Sharpy 70 kJ / m², according to ISO 179


There are two types of noise that vary widely in the medium through which is transmitted:
The noise of airborn (Airborn noise) The noise that is transmitted through the walls of buildings (Structureborne noise) Both types of noise can be reduced to optimal levels in different ways. The noise of airborn (Airborn noise) is reduced so that the pipes and fittings produced by special technology of special materials (materials reinforced-modified mineral additives) or by optimizing the use of fittings in places change of direction of the pipeline. The noise that is transmitted through the walls of buildings (Structureborne noise) is reduced so that the pipeline is installed properly with good quality clamps with molded rubber (fixed points) and the optimum tightening clamp (slip point). To determine the effectiveness of the sound insulation, the system of pipes and fittings for house sewage installations, Peštan S LINE system was sent for testing at the renowned German Fraunhofer Institute for Building Physics (IBP) in Stuttgart. The tests were carried out according to EN 14366 (Laboratory measurement of noise from waste water installations) and DIN 4109 (Sound insulation in buildings – Requirements and verifications) and Peštan S LINE system has shown excellent results
with the measured noise level of just 12dB (A ).
