DVGW cer tificate for high-pressure
pipe system
THE HexelOne® high-pressure pipe
system has been certified by the DVGW
for gas and drinking water applications.
The approved use of the plastic
pipe system in high-pressure settings
provides two benefits that previously only
applied to low-pressure applications:
the corrosion resistance of the pipes
makes cathodic corrosion protection
redundant, and the system allows the
use of modern installation techniques
that shorten construction time.
The reinforcement opens new areas
of use for egeplast’s HexelOne, with
permissible operating pressures of
30 bar for water and 16 bar for gas,
exceeding the range of applications
previously covered by PE pipes. The
stability achieved by the HexelOne pipe
with its reinforcement layer of high-
strength PE strapping is claimed to be
twice as high as that provided by PE-
100 full-wall pipes.
Owing to their protective layer and
inner layer made of PE 100-RC,
the pipes are suitable for trenchless
installation.
The DVGW certificate for drinking
water covers dimensions from d 90mm
to d 125mm. In addition, HexelOne gas
pipes have been certified for up to d
160mm.
