The PSI Association

For the legacy of Piping Stress Engineering
The PSI Association was created to provide a platform for the Piping Stress Engineers professional growth.
The social responsibility of the correct design and construction of piping systems requires a professional learning, therefore The PSI Association will contribute to it organizing meetings, seminars, round tables, webinars and networking events.
The legacy of the Piping Stress Engineering has to be preserved for future generations and The PSI Association is fully engaged with this idea.
For the privilege of sharing and for the legacy of Piping Stress Engineering.
