VTT ProperScan

Avoid production losses at extreme conditions


VTT ProperScan® service ensures uninterrupted and economical operation of extreme condition (high temperature, high pressure) processes e.g. energy production, pulp production and heat generation. We provide accurate action plan just in time to prevent production losses. Our expertise of material science, data-analytics and risk management as well as supporting research facilities cover the processes at temperatures up to 1500 °C. ProperScan® helps to find solutions for aviation, energy and process industries.


VTT ProperScan® offers API RP 579/ASME FFS Fitness-For-Service - assessment of ageing equipment for continued service

We carry out lifetime assessment for power plant components. Our lifetime assessment goes beyond the design standards and calculations based on those standards. Our lifetime assessment projects often include the following methods;

  • Microstructural characterization
  • Creep calculations and experiments
  • Finite element analysis


Our experts have deep understanding of fracture mechanics, fatigue measurements as well as crystal plasticity and its role in creep.

 VTT ProperScan® offers services for uninterrupted operation


With our help you can;

  • extend lifetime of your critical components
  • operate safely without unexpected shutdowns
  • reduce techno-economical risks of investments


Facilities for material research at extreme conditions

VTT has several world class research facilities to do research on material performance including mechanical and fracture testing, exposure testing in hot gas environment, water chemistry and electrochemical corrosion research, tribocorrosion testing, mechanical testing in simulated coolant environments, mechanical testing of activated materials and materials characterisation. We also have decision support tools, such as ReliaSoft (reliability engineering, modelling and analysis software) and Life Cycle Cost (LCC) calculation tools.



​​​Material research

The research facility provides extremely broad coverage of different areas of material testing. The Research Hall houses autoclave laboratories, a non-destructive testing laboratory, a creep laboratory, a hot corrosion laboratory, and fatigue-testing equipment. 

​ ​​​


VTT holds strong expertise on corrosion phenomena and prevention in a wide variety of applications and environments. We offer our customers high-quality knowledge and facilities for corrosion research, monitoring, modelling and prevention methods.


 VTT offers its customers profound knowledge on tribology (friction, wear and lubrication), top-level testing equipment, a computer modelling approach and international networking opportunities.

How do we serve you?

We will form an expert team to discuss with you about the challenges at your plant and how to tackle them. After the content of the project has been agreed with you, we will prepare an offer and ask the information and samples needed for testing and characterization. If all information we need for analysis is not available we can carry out experiments at laboratory or your site. 

After we have analyzed the test results we will provide you a report with action points.

BALTICA conference

A series of Baltica conferences concentrating on power plant maintenance and life management have been organised initiating from the 1980’s. The latest Baltica XI was organised in June 2019. The Proceedings of the Baltica X (2016) conference are available: International Conference on Life Management and Maintenance for Power Plants.
Next BALTICA conference will take place in 2022.
