Aquatechnik multi-layer pipes for Mater Olbia Hospital
The heating, air conditioning and thermal power plants
of Mater Olbia Hospital were built with multilayer pipes from the faser line
and fusio-technik fittings.
Recently founded, the Mater Olbia Hospital is
the result of the partnership between the Qatar Foundation Endowment and the
Fondazione Policlinico Universitario Agostino Gemelli
IRCCS of Rome. Combining the skills and
respective experiences, a hospital of excellence is born at the service of the
Gallura Territory and for the whole Sardinia.
Design choices: fiber-reinforced pipes
With an avant-garde structure and new health services
for citizens, the polyclinic represented an interesting project where to utilizes
our solutions, that were handled with undisputed professionalism by our
installer partner Impianti Generali SRL of G. Pagin of Latina.
Aquatechnik systems can be used in the most
diversified sectors: the performance advantages of multi-layer fiber-reinforced pipes make them particularly suitable also for the
service sector. Moreover, thanks to a linear thermal expansion reduced by
70% compared to single-layer pipes, the laying and clamping processes are
facilitated.
The advantages of the faser range for the tertiary
sector
The technology of the fiber-reinforced fusio-technik
system is an important evolution for the single-layer systems: the already
remarkable characteristics of PP-RCT (random copolymer polypropylene with
modified crystallinity) are enhanced by the additives package WOR
(White Oxidation Resistance). This solution, studied by Aquatechnik in
collaboration with world leaders in the production of additives for polymeric
systems, integrates the composition of the pipe inner layer, made of PP-RCT.
It is a technology that allows, among other
advantages, also a high thermal and to metal ions stabilization, as well as
greater resistance to chlorine. This last factor is particularly relevant
for the usage in hospitals, where the water is subjected to significant
chlorination and where periodic anti-legionella treatments are often provided.
The numbers confirm the advantage: laboratory tests
show how the WOR technology increases the resistance to oxidizing agents
such as free chlorine, chloramines, chlorine dioxide and similar up to 40
times compared to a normal PP-R. Furthermore, these are pipes suitable to
transport hot or cold drinking water and other fluids intended for human
consumption, in compliance with current regulations, such as the European
Regulation 10/2011 and the Italian Ministerial Decree No. 174/2004 and NSF 61 /
NSF 51.
The composition of the fiber-reinforced fusio-technik
system
The faser FIBER-T SDR 7.4, faser FIBER-COND SDR 11 and
faser FIBER-LIGHT SDR 17.6 pipes have an internal surface made of PP-RCT WOR
with high long-term resistance (MRS 12.5 MPa). The central layer made of
PP-RF (fiber-reinforced polypropylene copolymer) guarantees a drastic
reduction of stretching due to thermal expansion, while the outer layer, in
PP-R 80 Super, gives the pipe adequate ductility and resilience. The
diameter range extends up to Ø 400 mm.
Easy installation with fusio-technik fittings
The fusio-technik
fittings contributed to make the
installation of the Aquatechnik systems at Mater Olbia Hospital more practical
and quicker. Simplicity also guaranteed by the wide range of fittings,
made of PP-R 80 Super and PP-RCT.
The parts are joined by polyfusion (socket welding up
to a diameter of 125 mm, butt-welding for larger diameters), guaranteeing total
safety in the pipe-fitting passage and resistance to even violent impacts.
