6
Fuel nozzles including Dry and Ultra
Low NOx (DLN / ULN) - testing of air
flow and fuel flow, repairs, rocket
replacements and alignment verification
The state-of-the-art Repair Technology
Center (RTC) within our Repair Network
focuses exclusively on repair development for turbine components.
Turbine blades - full tip restoration,
shrouded blade contact pad restoration,
MCrAIY, TBC and hardface coatings, flow
testing, and moment weigh
The RTC allows reduced development
lead-time on key technologies in addition
to providing cost competitive repairs.
The RTC has expedited development
of strategic processes and technology
such as:
Fluoride ion cleaning (FIC)
Advanced laser welding (Alloy 247)
Narrow-and wide-gap brazing of ECY
768 and IN939 materials
Each year, Siemens invests millions of
dollars to keep its repair technology,
capabilities, and facilities on the leading
edge of the service solution industry.
Cutting-edge white light scanning that
creates a digital representation of your
parts and compares the image to an
existing 3-D model to show deviations
from the original specifications
Additionally, the RTC Met Lab is dedicated
to analysis for new process development.

Proven repair techniques
to extend the life of
your components.
The Houston Service Center provides
complete service of your parts from
inspection and expert advisement to
advanced repair, coating, and final
delivery.
Beyond common techniques, the Repair
Network applies advanced processes in
the following repair competencies:
Non-destructive examination (NDE):
At the Houston Service Center, multiple
inspection techniques provide the most
comprehensive diagnosis of your parts’
damage modes. Inspection is provided
through:
8
Coordinate measurement machine
(CMM) which measures precise
geometric dimensions of components
to show a more accurate determination
of the service run condition of a part
Infrared thermography (IR)
Radiographic testing (RT)
Magnetic particle testing (MT)
Ultrasonic testing (UT)
Eddy current testing (ET)
Fluorescent penetrant inspection
testing (PT)
Visual inspection testing (VT)
Full in-house coating capabilities:
The Houston Service Center utilizes a
fully closed-loop control system for
APS and HVOF coating of turbine parts.
Multiple coating booths are available to
handle specialized coating needs for TBC,
wear-resistant coatings (Chrome Carbide,
T-800), and many other advanced coating
techniques and materials. Coating preparation is achieved with automated grit
blasting, and on premises Production
Met Lab analysis allows for prompt verification of coating success. A full range
of in-house capabilities are available to
meet your coating needs on combustion
components, turbine blades, and vanes.
Advanced and mature fuel nozzle
repairs:
The Repair Network’s Houston facility is a
center of competence in the testing and
repair of fuel nozzles and support housings. A full range of testing is conducted
on DLN/ULN nozzles as well as a wide
variety of combustion components.
Upon analysis of testing results, repair or
complete replacement of components is
performed at the facility.
In-house product modifications:
As turbine parts are modified and
upgraded, design changes are implemented during the repair process to
help enhance product reliability and plant
efficiency. The Houston Service Center has
four heat treat furnaces and four vacuum
furnaces dedicated to development and
production for multiple components. Your
local platform team has specific details
and examples to share.
Machining and verification of turbine
parts:
Advanced equipment is used to machine
and verify components. The fiber-optic
laser welder with vision system permits
precise and accurate weld build-up on
complex material structures. The axis
milling and grinding machines probe and
recreate OEM airfoil and shroud profiles
and robotic APS and HVOF coaters repeat
programmed paths to ensure consistent
applications. Portable and table coordinate
measuring machines verify geometries
with the utmost precision. Calibrated
fixtures ensure that components meet
OEM specifications. Air and fuel flow testing is performed with fixtures for nozzles,
baskets, vanes, and blades.
Component identification:
Siemens’ repair facilities engrave a unique
identifier on each part, which allows us to
track every component during its service
life cycle. Siemens shares this information
with customers, as it helps maintain a
valuable part history for future reference.
Specialized component containers:
Siemens offers all-weather shipping
containers, specifically engineered to
house the critical-to-quality elements
of your parts for better protection during
transport and storage.
