S-Line Piping Solutions

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 12dB*. The latest technology of three-layer extrusion pipe and materials modified with mineral additivies have raised disposal of waste water systems within the building structure on a higher level.

Chemical resistance of materials

Peštan S LINE pipes and fittings are resistant to salt water, alcohol, acids, alkalis, sulphates, aggressive gas and all kinds of detergents. On the other hand, can not be used for the transport of water which contains high percentage of benzene, benzine (petrol) or acetone.

Connecting S LINE pipes

Peštan S LINE pipes and fittings are connected via sockets, a water resistance is achieved through the sealing rings made of EPDM rubber (EN 681), which are inserted into the socket.

Installation and testing

Pestan S LINE pipes and fittings are installed in accordance with EN 12056 Gravity systems inside buildings.

Testing of internal sewage is mandatory in modern residential construction.

The pipeline should not overlap prior to the execution of the test, all connections must be visible and clean. All openings must be temporarily closed during the test water resistance. The water with which the watertightness is tested should be dry. Overpressure testing water resistance ranges from a minimum of 0.03 bar to 0.5 bar maximum. Tightness test takes an hour. Criteria for passing the test water resistance is to not lose more than 0.5 liters / hour for every 10 m2 of internal surface of the pipeline.

Reduction of noise

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 (Structure-borne 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 (Structure-borne 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 ).
