ADVANCED SOFTWARE
& TECHNIQUES
Combining Belman Groups’ extensive Expansion Joint know-how with use of advanced engineering tecniques and advanced and recognised softwares the engineering team is able to create, analyse and verify Expansion Joint designs, no matter how specialized the design is.
Softwares used:
- Rohr2
- ANSYS – Finite Element Analysis (FEA)
- VVD
- BelMaker® (inhouse developed software)
BELMAN IN ROHR 2
In some piping design softwares such as Rohr2 the user is allowed to select Expansion Joints from a manufacturers list. In the Rohr2 software you will find Belman Group on the manufacturers list. That enables you to implement Belman Group Expansion Joint data into your piping designs.
All Expansion Joint types can be created requiring data such as:
- Regulating powers
- Spring rates of bellows
- Mean Diameter of Bellows
- weight of the unit etc.
