Product range Ultra DB ®

Unique System of silent sewage pipes and fittings dB Ultra System is a high-quality product from Polypropylene containing a large amount of mineral filler. This material lends waste pipes and fittings dB System Ultra excellent mechanical and acoustic properties which significantly reduce the intensity of noise penetrating through the pipe wall to the surroundings. Ultra dB System is thus predestined for all areas of civil engineering (family and apartment houses, industrial, cultural and sports facilities, hospitals, hotels, etc.)..


Maximal operating temperatures of pipes, adapting pipes and sealing

constant short-term
90°C 100°C

Sealing Area of application- temperatures
SBR (at the producer /within the range of Work) cca. -50°C up to +100°C
EPDM cca. -50°C up to +150°C
NBR (can be ordered separately) cca. -30°C up to +100°C

SBR Improved abrasion resistance and age resistance, good resistance against operating liquids
EPDM Excellent fastness to abrasion, ageing and fastness to most of operating liquids
NBR Versatile material. Sealing for contact with mineral oil or fuels. Poor resistance against ozone and weather resistance
Skolan dB (DN 56 - DN 200) according to the standard DIN 4102 - B2 a according to the construction supervision certificate Z-42.1-217

We can recommend KG 2000 Polypropylene®, or HT-System (PP) ® with sealing rings made of NBR as the case may be.

Skolan dB DIN 4102, B 2

The sealing of systems BL, DD and Euro L Spezial are resistant against water with maximal volume of chlorine 0.6 mg/l.

See the Test record of MPA Darmstadt „K 05 1497" of 11th November 2005 (the pipes DN 50 were tested).

No, it cannot. 
Among other things, this provision serves for elimination of the backwater formation and formation of retained amount inside the system.

These details can be found in the assembly instructions of HT-System (PP)® - Article 5 and assembly instructions of Skolan dB – Article 7.

It is necessary to install a felt bag (or other materials commonly available in the network of shops) onto the Skolan dB pipe placed (the pipe for rain water). In case of the rain water piping only the upper floors are mostly insulated in practice. Basically, the Skolan dB pipe has a high coefficient of insulation. Formation of the condensing water from dew formation does not occur at the plastic pipes with reinforced wall compared to conventional cast-iron or steel pipes. For that reason the above-described insulation is sufficient.

The pipes with slide-in sleeves / couplings are usually placed in such manner that the sharp end is in direction of flowing. The sharp end is sliding into the sleeve / coupling.

The quote from Manual of plastic pipes (4th issue, paragraph 3.4.4 Construction of the sewage water channels and piping, page 463)

Thus the piping placement in direction of flowing is clearly defined.
