SULZER TURBO SERVICES VENLO Capabilities: REPAIR, NOT SCRAP !!
Rescued from scrap
Sulzer Turbo Services Venlo (TS Venlo) has always pushed the boundaries and is a pioneer in
the search for new techniques to repair even the worst condition parts. For this we have
successfully developed repairs using laser welding and other special processes. We have
attached a few examples were we have rescued components from SCRAP were other
competitors, including the OEM, were not able to repair. These parts are now running safely in
turbines.
Lowest price suppliers in many cases scrap or reject many components since these companies
are both financially as well as technically not able to effectively refurbish gas turbine hot section
parts. TS Venlo however is recognized in the Industry for the low scrap rates and high quality
and therefore we have rescued/repaired a lot of parts for customers and prevented the
customer to buy very expensive NEW parts from the OEM. If orders would have been evaluated
afterwards and not only at the tender opening, TS Venlo would have been the better
alternative, taking into account that NO replacement of scrap parts by NEW parts would have
been necessary.
We at TS Venlo have invested a lot of efforts in the Research & Development for new repair
techniques to RESCUE customers parts from being scrapped. We are successfully offering
these special repairs to our customers.
On the following pages several of many examples are showed to emphasize which parts &developments (processes) we have used to rescue components from scrap. In addition, TS
Venlo is able to provide non-OEM new manufacturing of gas turbine components instead of our
existing refurbishment technology, if customer wishes.
For more information, Please do not hesitate to contact us.
Yours sincerely,
