Geberit Drainage Systems Introduction Geberit Silent-db20 overview Geberit Silent-db20 is a drainage system for buildings Advantages of the Geberit Silent-db20 system: with increased levels of sound proofing. Its outstanding • Improved acoustic properties. acoustic insulation properties are achieved by: • Geberit Silent-db20 pipes and fittings are compatible • Patented high density material specifically developed with the existing Geberit HDPE Drainage System.
The density of polyethylene varies between 910 – 960 kg/m . Geberit HDPE, up to 955 kg/m is of the highest quality and has excellent durability. HDPE is light weight, which is beneficial particularly with regards to handling, transportation and installation. Geberit Silent-db20: Density 1700kg/m3 Increased density improves acoustic properties.

Thermal expansion 0.17mm/m.K Heat expansion of Geberit HDPE is relatively high. As a rule of thumb, for every 50°C increase in temperature, an expansion of 10mm per linear metre of pipe can be anticipated.

Joint integrity Many years of experience with welding Geberit HDPE pipes have shown that butt welds do not give any problems as the welding parts are circular on the inside and do not add to the normal risk of blocking.

Silent-db20 is approximately 230°C. Simple tools allow for easy processing. Non-toxic Plastics are well suited for use in the food industry as packaging materials, containers, bottles etc. Geberit HDPE pipes are used for milk transportation lines in mountain areas and in the food canning and packaging industry. Working pressures Geberit HDPE and Geberit Silent-db20 pipes are designed for drainage systems.

Jointing methods Jointing methods Within an ever more competitive culture, installers The many Geberit jointing methods offer solutions for and specifiers are continually striving to reduce costs, all situations and each type of connection has different labour and materials used in the construction process.
A simple reliable connection. Application Butt welding is the easiest jointing method, providing the many advantageous benefits of prefabrication; Geberit HDPE needs no other component in order to be butt welded. It can be used in all circumstances where prefabrication Hand Mitre Saw is used on site or in the workshop.
Geberit Drainage Systems Jointing methods Butt welding by hand A Geberit welding plate KSS-160 or KSS-200, 4.1.1 must be used. (for pipes Ø 40 to 75mm) Check temperature Indicative values fo r welding and warming up times. of the welding plate.
Geberit Drainage Systems Jointing methods Butt welding by machine A Geberit MEDIA 160 or UNIVERSAL 315 welding 4.1.2 machine must be used. (for pipes Ø 40 to 315mm) Place pipe parts in the tension plates and fix them in a line.
3.5 cm The joint obtained is simple, quick and strong once made. The heater wires remain encased in the HDPE so there is no chance of corrosion. The use of Geberit approved Remove burr. Welding ends must remain dry during the equipment and fittings is essential to ensure a good weld whole welding process.

Geberit Drainage Systems Jointing methods Electrofusion coupling A Geberit starter switch ESG – T2 (230v) or Advance Welding 4.2.2 AW315G (110V) electrofusion machine must be used. (for pipes Ø 200 to 315mm) Dry, clean, scrape or abrade welding ends to full insertion Geberit electrofusion depth.
Geberit Drainage Systems Jointing methods Ring-seal sockets Conversion to a 4.2.3 slip coupling To turn the coupling into a slip coupling, the central ring can be removed as shown below. B.500.000/191 Available from Ø 40 to 160mm. Connection properties a Non-rigid, removable.
The pipe must be fully inserted into the socket, because the socket does not act as an expander. Owing to the pipe Connection properties thickness and the low thermal conductivity of HDPE, the a Non-rigid, demountable joint. socket seal has a very satisfactory resistance to heat and b Non-tension-resistant.
Geberit Drainage Systems Jointing methods Flanged joint Available from Ø 50 to 315mm. Connection properties a Rigid, mechanical joint. b Tension-resistant. c Demountable. Application Flanges are normally used as demountable joints for low pressure installations (industrial plant, pump connection, tanks and swimming pools).
This type of joint is also used for connection to pipe spigots in other materials. The standard version is to be buttwelded onto the Geberit Flange bushing HDPE pipe end and the extended version (available in certain diameters) can be electrowelded or buttwelded onto the pipe end.
Geberit Drainage Systems Jointing methods Jointing methods for Geberit Silent-db20 Geberit Silent-db20 uses the normal HDPE jointing methods including butt welding, electrofusion couplings, and mechanical couplings. If using butt welding the plaining blades fitted to the butt welding machine must be changed to carbide steel blades –...

They may also be used for For all fixations of Geberit HDPE pipes Ø 40 - 315mm underground drainage applications, provided the pipe except for anchor brackets.
Contact Geberit Technical for advice. please see section 5.2.1 for additional data on fixing using drop rods. Geberit Silent-db20 pipes are to be fixed with anchor brackets and guide brackets. The distance between the anchor bracket and the guide bracket is maximum of 6 metres or nominal outside diameter spacing of guide brackets whenever stability is required in the system.
The thrust force is the slide resistance between << >> the rubber seal and HDPE pipe. This force depends on the pipe diameter.

Geberit Drainage Systems System installation Horizontal installation For horizontal pipework the position of the expansion joint will vary. 1 On the long runs of pipe with no branch connections, the expansion fitting must be fitted at a maximum of 6 metre centres.
Geberit Drainage Systems System installation Deflection Leg - Guidance on use 5.2.2 A deflection leg is a length/section of pipe specified within the system to accommodate the movement as a result of thermal movement. Deflection legs for pipe lengths of greater than 15m are not recommended as the bending leg will be larger than the maximum bracket spacing.
Rigid fixing of the Geberit HDPE system can be achieved by using a proprietary bracketry system (that may in incorporate struts or very strong drop rods) or the Geberit Pluvia rail system, as outlined below.
Page 43
Rigid fixing - Anchor brackets Rules: Anchor brackets must be stronger than the possible forces generated during thermal expansion or contraction of Geberit HDPE pipes. Examples of anchor brackets: The examples of anchor brackets below show typical rigid installations. Anchor bracket with flat iron and electrowelding tape.
W = indication coefficient for steel profile. Suspended rail system 5.2.4 The Geberit Pluvia rail system was developed for the suspended installation of horizontal pipework. The system includes a metal rail that absorbs all the forces generated when the pipe tries to expand.
