Power Plant Overhaul
Zeros GmbH has been a reliable partner for power plant overhauls and non-destructive testing (NDT) worldwide for over 25 years. Using state-of-the-art testing technology and internationally trained specialists, we ensure the maximum safety and availability of your facilities.
Overhaul of a 12.5 MW steam turbo set with UT and PT inspections on valves, bearings, gear tooth volume inspections as well as MT inspections on turbine housings and blades.
A regular power plant overhaul is essential for operators to ensure operational safety, avoid unplanned outages, and detect potential damage early. With our non-destructive testing methods – including ultrasonic testing (UT), magnetic particle testing (MT), dye penetrant testing (PT), visual testing (VT), phased array as well as mobile X-ray inspections – we ensure that even complex components can be reliably assessed.
Inspections include turbines, rotors, generators, valves, housings, bearings, and blades. This secures the efficiency and longevity of key plant components.
In practice, we recommend an overhaul every 3 to 5 years, depending on plant type, operating conditions, and operator requirements. Through our global network, we can offer these services not only regionally but also internationally – including all logistical and regulatory requirements.
