The pipes in a district heat exchanger have to be replaced, because they leak due to corrosion damage. Maintenance is time consuming and expensive.  

Helsinki Energy contacted Helsinki University of Technology with the problem to investigate the source originating problem – How, when and what kind of corrosion is formed. The problem were distributed in the three entireness; drying the pipes in the heat exchanger before maintenance, conserving pipes in corrosion preventing solution and the optimizing pipes material.

The project ProTube produced the answers to questions – How, when and what kind of corrosion is formed in the pipes in a distributed heat exchanger. The project was done in cooperation with Helsinki University of Technology and Helsinki Energy. The results were able to define the best ways to ease the problem in a long term.

The research was executed in cooperation with Helsinki University of Technology at the Product development course.

The project is part of the Innovative City® Program.
