Turbine Services Ltd parts are manufactured using TSL®’s unique combination of turbine specific engineering, manufacturing and testing, ensuring the highest quality product to our customers.
Since 1972 TSL® has engineered more than 600 turbine components. This includes more than 50 rotating blade styles, equiaxed and directionally solidified. We manufacture 30 different varieties of stationary vanes and diaphragms made of high strength nickel alloys and corrosion resistant cobalt alloys.
With 35 years of supplying parts which represent millions of aggregate turbine operating hours, TSL®’s engineering vast experience and expertise has established a reputation of a reliable source for the manufacturing of gas turbine replacement parts.
TSL® engineers only use state-of-the-art equipment and technology to analyze and design turbine components these include:
- NVision and GOM - ATOS for laser and white light 3D scanning of components
- PTC® Pro/Engineer and Kubotek® KeyCreator for 3D modeling and design
- Algor®, finite element analysis for structural, vibration and heat transfer analysis
- Stereo lithography prototyping for verification of design
These tools allow our engineers to design, verify and validate parts that equal or exceed OEM standards, while drastically reducing our product-to-market development cycle.

Brush Seal Technology
Turbine Services Ltd. brush seal technology improves efficiency with advanced sealing while drastically reducing leakage normally associated with standard seal technology.
Traditional technology used for managing airflow, such as fixed labyrinth seals, is usually installed with unyielding clearances. These metal teeth tend to bend, jeopardizing the seal's integrity and compromising efficiency. Turbine Services, Ltd. brush seal's flexible bristles retract back into its precise positioning while handling critical vibrations suffered under normal operating conditions.
With performance improvements of 1.0% in output and 0.5% in heat rate, the Turbine Services, Ltd. brush seals are a more efficient alternative to standard seals.
Advantages of Brush Seals include:
- Improved Durability
- Increased Efficiency
- Substantial Performance Improvements
- Reduced Leakage
- Operating Clearance Reduction
Service Life Plus
TSL® engineering has developed the SL+™ package of improved gas turbine combustion parts. SL+™ combustion components increase unit availability by extending the gas turbine combustion inspection interval beyond industry standards. This is achieved by improved clearances, addition of wear resistant materials and addition of thermal barrier coating.
More specifically, SL+™ is applied to the following combustion components (see next slide).
Combustion Liner
Hard face coating on hula skirt, liner stops, cross fire tube collar and fuel nozzle collar ensures better positioning of the liner in the sleeve eliminates the possibility of axial interference and increases wear resistance of the liner
Cross Fire Tube
Hard face coating on mating surface reduces clearance and increases wear resistance
Transition Piece
- Guide Block/ Bull horn: Hardened inserts on H-blocks and mating bull horn surface;
- Picture Frame/ Floating Seals: Improved seals design and picture frame clearance;
- Thermal Barrier Coating: Reduces metal temperatures.
Fuel Nozzle Tip
HVOF (High Velocity Oxy-Fuel) hard face coating increases wear resistance and reduces radial interference (causing the liner stop to support the liner, not the fuel nozzle)
