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,

Peter van NeervenRegional Sales ManagerSulzer TS Venlo
