Blades and disk corrosion, blades or rotor cracking, rubbing between the labyrinths or diaphragms gland seals and the rotor, and pinion gear-bull gear tooth failure are some common steam turbine failures. Depending on the solution chosen, these failures may result in long downtime and high expenses.
Deciding to repair and not replace the steam turbine is usually the most cost-effective and fast solution. Some of the most important criteria analyzed before choosing a vendor are expertise, in-house manufacturing capability as well as the vendor’s ability to offer fast, flexible solutions.
Following the company’s extensive engineering and manufacturing capabilities, KIMI has been offering steam turbine repair services for more than two decades. The company undertakes the inspection, and basic and advanced repairs of all types of marine, power and industrial steam turbines. After detailed inspection, condition evaluation and reporting are carried out, KIMI proceeds with the repairs which usually include manufacturing or re-manufacturing of critical parts such as:
- Rotating and Stationary Blades
- Nozzles/Diaphragms/Guide vanes Labyrinths
- Journal bearings, thrust bearings, bearing pads
- Bearing pockets
- Complete rotors
- Bull gears and pinions
- Reduction gearboxes
- Couplings
For steam turbine repairs laser cladding method availability is also a key criterion in choosing vendor. Laser cladding is the only sustainable, delicate solution for the restoration of critical components, especially rotors, damaged by erosion or wear. The most important advantages of this method are the strong metallurgical bonding between the layer and the substrate, the minimal heat input during the process and distortion caused to the part and the part’s higher resistance to erosion after the repair.
Except for our expertise and long proven track record, KIMI offers fast response and short lead times, minimising in that way customer downtime. Specialised technicians are available to travel round-the-clock worldwide for inspection, fault diagnosis and other in-situ services required.
