Red-Bag User Day May, 2019 took place in the new industrial location of RDM Rotterdam. We have had a successful start of the Technical Journey with a motivated group of participants.

Flange bolt unloading

Many of us have the impression that the bolt stress will go up when a flange pair in a pipe system is pressurized after assembly.

Invitation User Day 2016

Red-Bag is conducting a user day on April 5, 2016 in Rotterdam. The registration is open for users of the Red-Bag software. The registration is closed, 2016.

The main purpose is to meet other colleagues and to share experience.

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.
