Maintenance Service
At Coretech Energy, we deliver comprehensive maintenance, repair, and spare parts services for power plant rotating equipment with a focus on steam and gas turbines. Our solutions are engineered to maximize availability, increase operational efficiency, and minimize unplanned downtime through industry-leading practices and expert execution.
Steam Turbine

Coretech Energy provides full-scope steam turbine maintenance services covering inspection, overhaul, repair, and commissioning support. Our experienced field teams perform detailed mechanical inspections, blade and diaphragm checks, sealing and bearing maintenance, and dimensional controls to restore turbine performance and extend operational life. We support both planned outages and emergency shutdowns with precise execution and detailed technical reporting.
Gas Turbine

Our gas turbine services include inspection support, hot gas path maintenance, combustion system checks, and auxiliary system servicing. Coretech Energy focuses on restoring performance, minimizing downtime, and improving reliability through structured maintenance procedures and qualified technical teams experienced in power generation gas turbines.
Generator

We provide generator inspection, mechanical and electrical checks, bearing maintenance, alignment control, and operational support. Our services are designed to prevent unplanned failures, improve reliability, and ensure long-term performance of generators operating in thermal and combined-cycle power plants.
Electrical Works - I&C

Coretech Energy delivers electrical works and instrumentation & control (I&C) services including installation, inspection, testing, calibration, and troubleshooting. Our teams support power plant systems such as protection circuits, sensors, control loops, and field instrumentation in compliance with industry standards and site safety requirements.
On-Site Machining

Our on-site machining services eliminate the need for component disassembly and transport. Using portable machining equipment, we perform precision repairs such as flange facing, bore machining, shaft restoration, and surface corrections directly at the power plant, reducing outage duration and overall maintenance costs
Rotating Equipment Maintenance

We provide maintenance, repair, and inspection services for pumps, compressors, fans, and other rotating machinery. Our approach focuses on mechanical integrity, alignment accuracy, bearing condition, and vibration behavior to ensure reliable operation and extended equipment life.
Low & High RPM Balancing

Coretech Energy performs low and high RPM balancing for rotors, fans, shafts, and turbine components. By applying precise balancing techniques, we reduce vibration levels, protect bearings, and improve overall equipment reliability during operation.
Vibration Analysis & On-Site Balancing

Our vibration analysis services identify root causes of mechanical issues such as imbalance, misalignment, looseness, and bearing defects. Combined with on-site balancing capabilities, we provide fast and effective corrective actions to prevent failures and optimize rotating equipment performance.
Steam Turbine Blade Manufacturing

We supply steam turbine blades according to original specifications or reverse engineered designs. Coretech Energy ensures material quality, dimensional accuracy, and aerodynamic performance through controlled manufacturing processes and quality inspections.
Steam Turbine Blade Replacement

Our field teams perform steam turbine blade replacement during outages with strict quality control. Services include blade removal, installation, clearances adjustment, and final inspection to ensure proper turbine performance and long-term operational safety.
Reverse Engineering

Coretech Energy offers reverse engineering services to reproduce turbine and rotating equipment components when original spare parts are unavailable. Our process includes detailed measurement, material analysis, design validation, and manufacturing support.
Sandblasting Works

We provide industrial sandblasting services to remove corrosion, coatings, and surface contaminants from turbine components, structures, and mechanical parts. Proper surface preparation ensures coating quality and long-term equipment protection.
Turbine Insulation Works

Our insulation works reduce heat losses, improve personnel safety, and protect turbine systems. Coretech Energy designs and installs insulation solutions suitable for high-temperature power plant environments.
Non-Destructive Testing (NDT)

We perform NDT services including ultrasonic testing, magnetic particle inspection, dye penetrant testing, and visual inspection. These methods allow early detection of cracks, material defects, and structural issues without damaging components
Spare Parts Supply

Coretech Energy supplies OEM and high-quality aftermarket spare parts for turbines, generators, and rotating equipment. Our logistics and technical support ensure fast delivery, correct part selection, and reduced downtime for power plant operations.
