Design and engineering requires hands-on experience. The engineering calculations are difficult to assess without this experience. Although Red-Bag is a software company we believed this experience is crucial to giving adequate support to our customers. Red-Bag is finalizing the calculation software as per EN1591-2014. This calculation method is very detailed and complex. The Red-Bag software engineers together with engineers of Gasunie followed the course of flange management at Dijkgraaf-Support B.V. The images give an overview of the practical exercises supporting the theory as presented in the class room.
