ROHR2 training - individual and group training

Thank you for your interest in a ROHR2 pipe stress analysis training

We hope that you enjoy the training and we try to do our best for your successful and profitable information.

We recommend a 2-day training for an introduction into ROHR2 for standard handling, results documentation and discussion of customer related topics and the or 3-day course for enhanced knowledge .

The training groups are kept small to guarantee a maximum  learning succes. Most of your technical questions will be answered directly in context with the training examples.
