Siemens provides comprehensive and costeffective oil system and piping services.
Our work in the power generation industry
for over 35 years has enabled us to provide
major improvements in the lube oil, seal oil
and piping technologies. Siemens’ dedicated
team of engineers and technicians utilize
this experience to effectively analyze and
provide tailored solutions for your fluid
systems.

Features
Piping inspection and repairs
Engineered high velocity oil flush
As in all systems, piping can degrade as
it reaches the end of its design life or
due to other factors. Long-term exposure to heat and/or water can accelerate
degradation, creating a need for more
frequent inspections. Siemens provides
a comprehensive inspection service for
piping systems to look for existing and
potential system failures. Fiber optics are
used to visually inspect and locate problems in areas such as guarded oil, seal oil
and generator gas piping systems. Predesigned piping kits reduce the time
The engineered high velocity oil flush is
a unit-specific, sequence-controlled procedure that removes oil system contaminants. Critical elements that accelerate
the cleaning process are three-micron
absolute high efficiency filters, specially
designed adapters for quick connects/
disconnects and above normal high
velocity oil flows. All bearing oil and seal
oil supply lines are individually sampled
to monitor progress and verify the lube
oil system’s cleanliness. During the high
velocity oil flush, real time ISO oil sampling data is used to trend the cleaning
progress. Final acceptance criteria is
based on Siemens’ full-flow sampling
method, which monitors particle
quantities collected through a 150mesh strainer for 30 minutes.
required for modification and repairs.
Engineered hydro blast
Significant amounts of water in the oil
system can lead to oxidation of the lube
oil piping causing a heavy layer of scale
build-up. The hydro blast process uses
high-pressure water, in excess of 9000
PSI, to blast the scale from the piping
surface. An oil rust-inhibitor is applied
to protect the piping from oxidation,
followed by a high velocity oil flush of
both supply and drain lines to remove
debris.

Chemical Cooler Cleaning
Over time, sludge and debris can build
up, reducing the heat transfer ability
of the coolers. Equipment damage may
occur as dirt gets pushed out of the
coolers into the rest of the lube oil
system. Cooler cleaning is essential to
maintaining lube oil system cleanliness.

cost-effective oil system
and piping services
Upgrades
Siemens’ investment in R&D has produced many upgrade options to help
improve system efficiency and reliability.
New designs in filtration, inlet piping,
control oil and seal oil systems are available for your unit and can be installed
during most scheduled outages.
Upgrade options include:
Steam chest and inlet piping
replacement
Combustion turbine rotor air filter
and inlet heating installations
Duplex filter assemblies to replace
air-side and hydrogen-side Cuno filters
In-line bearing oil filtration
High efficiency coolers
Our goal is to maximize your unit reliabilty
Knowing the design basis for turbine-generator oil
requirements, Siemens uses an engineeringintensive approach to identify root cause issues rather
than merely treating symptoms. Our goal is to provide
cost-effective, value-added and tailored solutions to help
you restore your system to full operating capacity for
maximum unit reliability.

Modifications to the guarded oil
piping to simplify cleaning and
inspection
Improvements to steam drain
ventilation and gland steam systems
Upgrades to control system piping and
components.
