DUKTUS PIPES fOR fIRE-ExTINGUIShING WATER PIPELINES<br />
The “Sonnhalde” area in Switzerland’s Emmental<br />
region is well equipped to deal with<br />
fires<br />
To enable adequate quantities of fire-extinguishing<br />
water to be supplied in the event of a fire, the<br />
municipalities of Rüderswil and Lützelflüh in the<br />
canton of Berne have connected the Sonnhalde<br />
residential area to the public water supply. Sonnhalde<br />
was previously supplied by the Sonnhalde<br />
private water supply association, but this was<br />
unable to provide enough water for fire-extinguishing<br />
purposes. Plans for the project were<br />
worked out by the consulting engineers H.R.<br />
Müller AG of Bremgarten in the canton of Berne.<br />
The laying work had to be done in winter, when<br />
vegetation was sparse, and in the severe cold. An<br />
added difficulty was that the soil conditions varied.<br />
<strong>Duktus</strong>’ sales and distribution partner<br />
HAGENBUCHER was able to offer the right<br />
grade of pipe for these difficult conditions. Ductile<br />
iron pipes with a ZMU external coating and BLS®/<br />
VRS®-T joints were equal to these requirements in<br />
every respect.<br />
From an existing DN 125 pipeline, a 650 metre<br />
long DN 125 hydrant pipeline was laid to the municipal<br />
boundary of Lützelflüh as a first stage.<br />
Despite of the biting cold, the laying work, which<br />
was done by Anton Siegenthaler of Schwanden in<br />
The municipality of Rüderswil in winter<br />
A 650 metre long hydrant pipeline of <strong>Duktus</strong> DN 125 pipes ensures<br />
that there is adequate capacity for supplying fire-extinguishing<br />
water<br />
Laying of the hydrant pipeline in the Sonnhalde area in the<br />
Emmental region<br />
the Emmental region, was completed to an impeccable<br />
technical standard and on time, and the<br />
two Emmental municipalities now have a safe and<br />
reliable system for supplying fire-extinguishing<br />
water and an up-to-date way of fighting fires.<br />
The Škoda factory in mladá Boleslav puts its<br />
money on fm Approval<br />
In the course of work to expand the Škoda’s main<br />
site in Mladá Boleslav in the Czech Republic, it<br />
was necessary for fire-fighting systems to be expanded.<br />
The car maker will expand its capacity at<br />
the home works by 2012. In planning the fire protection,<br />
emphasis was placed on having the very<br />
highest quality.<br />
<strong>Duktus</strong> litinové systémy was able to supply exactly<br />
what the customer asked for: pipelines of ductile<br />
iron pipes with FM Approval. Jirí Mlynár, <strong>Duktus</strong><br />
Sales Manager in the Czech Republic, said: “Expansion<br />
is an important step in Škoda’s strategy<br />
for growth. The new M13 building was to be<br />
equipped with a safe and reliable fire protection<br />
Crucial to the placing of the order was FM Approval, which the<br />
<strong>Duktus</strong> pipes have<br />
190 metres of ZMU pipes was laid for the fire-extinguishing water<br />
pipelines in the Škoda plant<br />
system and FM Approval was a prerequisite for<br />
the placing of an order for the pipeline systems.<br />
This was a requirement that <strong>Duktus</strong> was able to<br />
meet. We supplied 190 metres of DN 300 nominal<br />
size ductile iron pipes with a ZMU external<br />
coating and the proven BLS®/VRS®-T joint. The<br />
ZMU coating stops the cast material from coming<br />
into direct contact with the soil, and this ensures<br />
that there is outstandingly good protection<br />
against leakage currents. This was also an explicit<br />
requirement which the client had, in addition to<br />
the FM Approval.”<br />
The first sod was turned to begin the expansion<br />
on 15 April 2011, on the occasion of the celebrations<br />
to mark the 20th anniversary of the association<br />
with Volkswagen. The work of laying the pipelines<br />
for fire-extinguishing water, which was carried<br />
out by KSK Praha, went off without a hitch<br />
and was completed in September 2011. <strong>Duktus</strong><br />
had already made a good impression in the Bohemian<br />
town of Mladá Boleslav in the spring of<br />
2011 when it supplied ductile iron drinking water<br />
pipes (see our report in <strong>inform</strong> 2/2011).<br />
