Customers can also take advantage of Turbine Services rotor exchange programmer. We always have available sufficient new or refurbished components to assemble turbine and compressor rotors at short notice. Customers are invited to benefit from this service. For cost-effective maintenance, customers may consider exchanging their operating rotor for a previously overhauled fully refurbished rotor which can be pre-delivered to site awaiting the next overhaul commencement

Pre–strip down balance and inspection:
Rotor balancing before disassembly to inspect all visual defects (VT) and unbalances that have formed on the Rotor.

Rotor disassembly:
Complying with safety and performance standards Gas Turbine Rotor disassembly is completed till Component level.

NDT facilities:
We provide VT (Visual Inspection), PT (Penetrant Test), MT (Magnetic Tests) & UT(Ultrasonic) testing to observe any defects or abnormalities, collection of data and in result quality insurance of the gas turbine components.



Rotor Overhaul Services

Individual wheel balancing:
Specification of any inconsistent weight distribution around the diameter of the rotor. Here in Kian Tec our field balancing capabilities include single and multi-plane balancing.

Rotor re-blade:
Inspection and Reparation of all Rotor Blades with appropriate


Rotor re-assembly:
All parts that were de-montaged (disassembled), repaired, renewed balanced and other maintenance processes that were performed will now be assembled with the same performance standards that were used for disassembly.

Rotor balance and run-outs:
Final Runouts are conducted so as to maximize efficiency and minimize vibrations, resonance and noise. Here in Kian Turbo Tec, we use the latest balancing solutions provided by SCHENCK according to ISO1940 standards to ensure the best results.

Comprehensive customer reports:
In order to meet customer expectations detailed full professional reports are prepared that indicates our step-by-step methods with accurate and need to know descriptions.
