Effluent pipes and fittings are made from polypropylene with mineral content, which grants them the ability to reduce noise intensity. The products conform to the CSN EN 1451-1 standard. All domains of civil engineering (family homes, apartment buildings, industrial, culture and sports structures, hospitals, hotels, etc.) that require silent operation.
The unique system of silent effluent pipes and fittings of Skolan SAFE dB is a quality product from polypropylene with a high content of mineral filler. This gives the Skolan SAFE dB effluent pipes and fittings excellent mechanic and acoustic properties, which significantly reduce the level of noise released from within the pipe into surrounding areas.
The unique system of silent effluent pipes and fittings of Skolan SAFE dB is endowed with an ability to reduce noise effectively right in the place where it occurs - inside the pipe; it can also prevent noise from diffusion in the pipe wall. This is possible due to the special molecular structure and high density of the material the composition of which has been patented. The polymer contains a mineral filler of high molecular weight and it has been subject to a number of tests, which have confirmed that the Skolan SAFE dB sewage system is capable of reducing noise.
As the quiet Skolan SAFE dB pipes and fittings introduce thick walls, they may reduce the noise to levels near the human hearing threshold. The noise levels that have been evidenced during the tests have been much lower than the requirement of the DIN 4109 - the standard that sets the noise conditions in areas that are to be protected from noise. The registered value of 21 dB(A) was even lower than the 25 dB(A) requirement of the stricter German standard VDI 4100. Our many years of production experience have confirmed what civil engineers had assumed: that only a thick wall and optimum material density are capable of effective noise reduction.
Skolan SAFE dB thick-wall pipes and fittings introduce a durable and robust design. The items are supplied in dimensions ranging from DN 50 to 160 with a thick wall and they are made from a material with a specific weight of 1.6 g per cu. cm. The high-quality material, surface treatment and quality package guarantee that Skolan SAFE dB meets even the extreme specifications of the most demanding of our customers.
Laboratory tests at the production plant and constant quality assurance throughout the production process serve as the guarantee of high and enduring quality. All management and manufacturing processes are subject to TQM and they meet the specifications of the EN ISO 9001 standard.
Thanks to its unique properties, Skolan SAFE dB delivers maximum conformance to stringent ecology and economy criteria of noise prevention. Whenever used in new buildings or in redevelopment, it undoubtedly enhances the standards of living, delivering higher value to the property.
