PiPeline neTWORKS:eneRGY eFFiCienT AnD SAFeOPTIMIZING FLOW PROCESSES!
Production and transportation of liquid
and gas consumer and industrial goods of
all types is unthinkable without the safe
and energy-efficient operation of hydraulic
pipeline networks. Pressure surges and
cavitation hammering, often caused by
closing or opening valves too quickly, can
significantly compromise safe operations.
The consequences include leaks, production
stoppages and even injuries to personnel
and damage to the environment.
Distribution networks also account for
a significant part of a production plant’s
operating costs. Based on more than 20
years of experience, the experts at Fraun-
hofer can provide almost every conceivable
type of practical and theoretical support in
designing and optimizing your water, gas,
hydraulic and chemical pipeline networks.

Our services
We calculate and optimize your pipeline
network. You enjoy the benefits of protection
against pressure surges, cavitation
hammering, impulse forces and vibrations
or disproportionally large accumulations
of condensables. Working with you, we
improve your valves and pumps on our test
benches. We check your pipeline networks
on site and determine the causes of hydrau-
lic or water hammering. We compute your
biogas reactors, check the performance of
your stirring units and create designs for you
for an energy-efficient production system.
