Sewerage system with low noise level SINIKON Comfort

One of the important indicators of the quality of sewer systems is the noise level of the system. The noise level in the room has a significant impact on the physical and mental state of people. Therefore, in developed countries, attaches great importance to the fight against noise. According to DIN 4109 (sound insulation in multi-storey buildings) noise level should not exceed 30 dB, and in more strict accordance with VDI 4100 – 25 dB. Russian norm SN 2.2.4/2.1.8.562-96 "Noise at workplaces, in residential and public buildings and residential areas" identifies acceptable noise levels during night time (from 23 to 7 hours) to 30 dB. To achieve such a level of noise even in well-designed sewer system with the use of conventional plastic pipe is often not possible. So for objects, which are increased requirements for comfort, it is recommended to use internal drainage system (noise absorbing pipe) SINIKON Comfort and VALSIR Triplus. Noise As a result of tests carried out at the Department of acoustics of Moscow state University. M. V. Lomonosov, it was found that the levels of noise in their pipes brands SINIKON Comfort and VALSIR Triplus hearing not differ from each other (difference less than 1 dB). Compared to standard PP-pipe the noise level in these systems are below 4 dB (A) 1.5 times when water consumption is 2.5 litres per second. By reducing the flow of water in pipes of up to 0.35 liters/second, this difference increases to 4 dB (A) to 7 dB (A) in 2.2 times. Purpose and scope Pipe SINIKON Comfort used for mounting non-pressure sewage systems for domestic sewage. Sewerage system SINIKON Comfort and VALSIR Triplus fully compatible with each other and with traditional polypropylene Sewerage systems in any configuration. Pipe SINIKON Comfort fully comply with all requirements of the applicable SP and SP 40-102-2000 40-107-2003. Domestic sewage may be short-term discharge of water with a temperature up to 80°C, short duration up to 1 min allowed temperature drains up to 95°C. They are intended for discharging chemically aggressive effluents with pH values of 2 (acidic) to 12 (alkaline environment). The service life of pipelines - not less than 50 years Pipe SINIKON Comfort with reduced noise Material Pipe and fingi SINIKON Comfort with reduced noise are produced by extrusion (molding of indefinite length by extrusion of polymer melt through the forming head with the channels of the profile) of the propylene homopolymer (type 1) PP - N with mineral additives and have an increased wall thickness compared with ordinary polypropylene tubes (2.7 mm to 3.4 mm for pipe DN 110).
